The 23rd Annual AMS Student Conference, which takes place 27–28 January (immediately prior to the AMS 104^th Annual Meeting in Baltimore), spotlights research by graduate and undergraduate students in the atmospheric and allied sciences, as well as offering networking and other career opportunities, presentations from leaders in the field, and the chance to hone important skills. We spoke with Conference Co-Chairs (pictured above, left to right) Melissa Piper of SUNY Albany, Angelie Nieves Jiménez of Colorado State University, and Dillon Blount of the University of Wisconsin-Milwaukee about what students will gain from the conference experience.

What’s behind this year’s Student Conference theme?

Melissa: This year’s Student Conference theme is “It’s Our Turn: Tackling Our Changing Environment.” We wanted to adapt the Annual Meeting theme (“Living in a Changing Environment”) to align with the rapid, multi-faceted changes students in the atmospheric sciences currently face. As students, our personal environments are constantly changing: we are going to school, moving for internships, and facing the unknowns of post-student life. On the flipside, our generation is entering adulthood in the face of a climate crisis. As we enter the workforce, we will be faced with developing solutions, conducting research, and adapting with our local communities to climate change. We hope that this year’s Student Conference can help prepare students to tackle these complex changes in all aspects of our lives.

What’s distinctive about the AMS 2024 Student Conference, and who should attend?

Melissa: The Student Conference is planned solely for students, by students from a variety of universities, backgrounds, and interests—so the conference is relevant to current students in the atmospheric sciences. There are professional development and networking sessions alongside research presentations constructed with students in mind (so no presentations that require you to have a PhD to understand!). Even better, the Student Conference Poster Session provides all students the opportunity to present their research at a reduced cost compared to the AMS Annual Meeting. A separate conference [also] gives students an opportunity to meet their peers from all around the world. This is especially important because we will all be each other’s colleagues in a few years!

While most tend to think of the Student Conference as being tailored to undergraduate students, we are making conscious strides in ensuring our conference is relevant to graduate students as well. We have sessions geared towards professional development, discovering lesser-known sub-fields in the atmospheric sciences, networking, jumping out of academia, and more!

Angelie: Additionally, the Career Fair on Saturday and Sunday nights is focused primarily providing students with information about internships and graduate school opportunities! We partner up with the Board of Early Career Professionals to bring professional development sessions for all stages.

The Student Conference takes place prior to the bigger AMS Annual Meeting, which can help students loosen up and prepare for the rest of the week and know what to expect. It also can serve as a trial of whether they wish to pursue the atmospheric sciences further.

Dillon: A conference geared towards students is a great way to get the students involved in the overall community of the American Meteorological Society. As students, we can often feel overwhelmed by the larger Annual Meeting and how to build a network throughout the week. This conference provides a great toolbox to use throughout the week to network and build community. This inclusion of students, and the resources gained at the Student Conference, allows students to help shape the future of the AMS.

What events at the conference are you most excited about?

Angelie: I am excited about the new Community Based Science Session which is inspired by what was previously known as the BRAID (Board on Representation, Accessibility, Inclusion, and Diversity) Session. This year we are focusing on presenting and highlighting the actions taken behind some of the amazing community initiatives.

Dillon: I am most excited about the Sunday keynote speakers! It is not often that students get the opportunity to hear from the top two leaders of the National Weather Service. Ken Graham and Michelle Mainelli’s leadership provides a great insight into what the future of that career field looks like. They are wonderful people, and I cannot wait to hear what they have to share!

Melissa: One of my favorite parts of the Student Conference is the Conversations with Professionals session. This year, we have an incredible lineup of 10 professionals from the private, public, and policy sectors for our students to have informal conversations with—including meteorologist-in-charge of the National Weather Service in Baltimore Mr. James Lee, director of the AMS Policy Program Dr. Paul Higgins, and broadcast meteorologist for WBAL-TV in Baltimore Ms. Ava Marie. It’s a fantastic networking experience!

In Short: Why Attend the AMS 2024 Student Conference?

Be There: The Kuo-Nan Liou Symposium

December 15, 2023December 14, 2023

Highlighting Key Sessions at AMS 2024

The Kuo-Nan Liou Symposium at the 104^th AMS Annual Meeting will celebrate Dr. Kuo-Nan Liou (1943-2021), a giant in the field of atmospheric physics who made crucial contributions in the areas of atmospheric radiation, remote sensing, and the greenhouse impacts of clouds and aerosols. Liou (pictured at right, image courtesy of Penny Jennings), received numerous accolades during his career, including the AMS’s Carl-Gustaf Rossby Research Medal and Charney Award, and he was part of the Intergovernmental Panel on Climate Change team who received the Nobel Peace Price in 2007.

We asked Symposium Co-Chair Ping Yang, University Distinguished Professor and David Bullock Harris Chair in Geosciences at Texas A&M University, about the Symposium and Dr. Liou’s impact. Here are some of his answers:

Dr. Kuo-Nan Liou (image credit: Penny Jennings)

Why are the areas of Dr. Liou’s research so important to understand right now?

As one of the most accomplished atmospheric scientists in the world, Dr. Liou made seminal contributions to atmospheric and climate sciences in many areas, particularly in atmospheric radiation. His radiative transfer model has been widely used in weather and climate models and satellite remote sensing implementations, and thus plays a central role in determining the radiation budget of the earth-atmosphere system and cloud-aerosol-radiation interactions and feedback in a changing world.

Radiative transfer is important because almost all the energy that drives the Earth’s atmosphere and ocean currents originates from the sun. Therefore, the climate of the Earth-atmosphere system is mainly determined by the radiation balance at the top of the atmosphere and the surface since radiation is the only mechanism by which the Earth-atmosphere system gains or loses energy.

What can attendees expect from the Symposium?

This symposium honors the legacy of Dr. Kuo-Nan Liou by bringing together researchers to share knowledge, foster collaborations and address current challenges in the fields where Dr. Kuo-Nan Liou left a lasting impact. Attendees, both in-person and virtual, can benefit from gaining insights into the latest research and advancements in these areas. Session topics include “Interactions Among Climate, Radiation, Clouds, Aerosols, and Surface”, “Radiative Transfer Theory & Spectroscopy,” “Remote Sensing of Clouds, Aerosols, and Surface Properties,” and “Light Scattering and Applications.” The Symposium will provide a platform for networking and engaging with experts and a forum for disseminating cutting-edge research findings.

The Symposium will delve into the forefront issues within these research areas. Noteworthy presentation topics include the lidar remote sensing of snow depth and density, sub-millimeter-wave remote sensing of ice clouds, Tibetan Plateau snowpack loss and its connection to extreme events, and more.

The first session aligns with the central focus of the 2024 AMS Annual Meeting, “Living in a Changing Environment.” It features invited speakers Drs. Ruby Leung, Dennis Hartmann, V. Ramaswamy, Zhanqing Li, Jonathan Jiang, and Yongkang Xue.

How did Dr. Liou influence the fields of atmospheric and climate science?

Dr. Liou’s work left a profound mark on the atmospheric and climate sciences due to his seminal contributions to radiative transfer, atmospheric optics, cloud-aerosol-radiation-climate interactions, and remote sensing. He was a pioneering researcher who demonstrated that atmospheric radiation should no longer be consigned to the fringes of meteorology, but instead should take a central place in the new world of climate science.

His book, “An Introduction to Atmospheric Radiation,” now in its second edition (with the first edition published in 1980), has been an invaluable resource for students and researchers around the world studying atmospheric radiation and its applications in climate science and remote sensing. Accepting the Rossby Medal in 2018, Prof. Liou talked about how his own early-career exposure to books like Chandrasekhar’s “Radiative Transfer” and Born & Wolf’s “Principles of Optics” spurred his innovations. For example, his simplified solutions for understanding solar and heat energy transfer problems, and his application of geometric optics to understand the scattering, absorption, and polarization properties of soot aerosols and irregular ice crystals.

He also humbly thanked his graduate students at the University of Utah and UCLA, saying, “They deserve to share, in equal measure, any recognition I have received, including this great honor from AMS.” We, the organizers of the Symposium, in turn are grateful to Dr. Liou. Along with his exceptional impact on the atmospheric sciences, he was a true role model as a leader and educator.

The Kuo-Nan Liou Symposium will be held Tuesday, 30 January, 2024 at the AMS 104^th Annual Meeting, in Baltimore and online; it will feature invited presentations and a poster session, along with a special luncheon. Learn more about the Symposium and view the program.

Be There: The Daniel Keyser Symposium

November 28, 2023November 28, 2023

Highlighting Key Sessions at AMS 2024

The Daniel Keyser Symposium at the 104^th AMS Annual Meeting will advance the science of synoptic-dynamic meteorology and celebrate the contributions of Prof. Daniel Keyser, a multifaceted researcher and educator. Keyser (pictured at right), a Fellow of the AMS and recipient of the AMS Meisinger Award and Lorenz Teaching Excellence Award, is well-known for his seminal work on cold-front updrafts and for co-originating the Shapiro–Keyser cyclone model.

We spoke with Symposium Co-Chair David Schultz, Professor of Synoptic Meteorology at the University of Manchester, about why the AMS community is celebrating synoptic-dynamic meteorology and Daniel Keyser’s contributions to the field. Here are a few excerpts:

How has Daniel Keyser influenced the field of meteorology?

Dan is one of those people who don’t get the attention they deserve. He’s worked on so many things and worked with so many people. Yet he’s done so in a very humble way.

A lot of what we know about cold fronts is from the work that Dan did. Dan’s PhD was about understanding the circulation of cold fronts and the dynamics of that interaction with the boundary layer in driving the updraft air at the leading edge of the cold front. Later, he developed the concepts of vector frontogenesis and partitioning Q/F vectors into front-normal or front-parallel flows, which help us diagnose the frontal-scale circulations and the larger synoptic-scale circulations in which they are embedded. Also, the concept of the Shapiro–Keyser cyclone model is now commonly taught in meteorology programs. The region of high winds called the sting jet, which is common in North Atlantic cyclones that may impact western Europe, only occurs in Shapiro–Keyser cyclones.

Not only has Dan been a great researcher, but he’s a great teacher at all levels, undergraduate and graduate. Much of my teaching philosophy comes from my time at Albany, from Dan and Lance Bosart. All four of us on the program committee, and so many others, have been influenced by Dan’s education over the years.

*The Shapiro–Keyser Cyclone Model, image taken from Shapiro and Keyser (1990)*.

Give us a few highlights of the Symposium’s program.

The first session gives a perspective on Dan’s career, including Dan’s work on wildfires and how he’s influenced others. Wildfire enthusiasts will want to check that out. The second session is called “Jets and Cyclones,” the meat-and-potatoes of Dan’s work. There will be a number of talks about various aspects of fronts, on the frontal scale but also up to the planetary scale, and how things like predictability and planetary-scale circulations in different climates affect the relationship between things like precipitation and fronts. Then, the third session will feature prominent mid- and senior-career-level people speaking about fronts and frontal circulation, zooming in on the smaller scale.

Session four is about fronts and precipitation, and it closes with Dan’s own presentation. Sub-seasonal effects, precipitation extremes, convection—for anyone interested in severe, hazardous, or extreme weather (for example, the flooding in California), that will be an important talk.

Why is a symposium on synoptic-dynamic meteorology so important right now?

Synoptic-dynamic meteorology is where meteorological research started, and weather forecasts are better because of our research. Now more than ever, people need to understand the dynamics of extreme weather and take a more interdisciplinary approach to weather systems. There’s a lot of hazardous weather out there, losses from weather events are increasing, and of course many people will experience climate change through its impacts on certain weather events. So synoptic-dynamic meteorology still lies at the heart of the problems that humanity faces and learning how to mitigate them. Yet, despite its importance, we’re at this point where we synoptic-dynamic meteorologists have to fight for recognition and institutional support.

That’s one of the things that Dan really wanted to emphasize in his talk at the end of the day: “A Personal Perspective on the Continuing Importance and Value of Doctoral Education in Synoptic-Dynamic Meteorology.” His talk will help people outside synoptic-dynamic meteorology see how these talks all day during the Symposium relate to the importance of synoptic-dynamic meteorology and to societal resilience in general.

The Daniel Keyser Symposium will be held Monday, January 29, 2024 at the AMS 104^th Annual Meeting, in Baltimore and online; it will feature invited presentations, a poster session, and a dinner with Keyser as the guest of honor. Learn more about the Symposium and view the program.

Irrigation and Storms in the Inner Mongolian Desert

A Research Spotlight from 32WAF/20Meso/28NWP

An irrigation oasis in Inner Mongolia, China, is providing unusual, real-world evidence about the effects of sharp vegetation contrasts on local and regional weather. Several presentations at the 32nd Conference on Weather Analysis and Forecasting, the 20th Conference on Mesoscale Processes, and the 28th Conference on Numerical Weather Prediction (32WAF/20Meso/28NWP) discussed findings from the 2022 DEsert-oasis COnvergence line and Deep convection Experiment (DECODE).

In Bayannur City, on the north side of a bend in the Yellow River, sits one of China’s largest irrigated areas: the 2,200-year-old, 769,333 hectare Hetao Irrigation District (HID), which was recognized as a World Heritage Irrigation Structure in 2019. All around this irrigation oasis is arid and semi-arid land, including the Kubuqi Desert to the south. We know that borders between land and water influence weather patterns, but there has been less real-world evidence gathered about the effects of differences in vegetation—and you can’t find a sharper divide than this one.

In the center of the photo is a dark green area of vegetation which contrasts sharply with the otherwise brown/tan landscape. A road runs to one edge of the green area. At the very right of the image, in the middle distance, is a large, wide building with a bright blue roof.

When cooler air from the Irrigation District meets warm wind from the desert, an atmospheric boundary line can sometimes be seen on radar. During the summer, convection often initiates at this boundary—sometimes leading to impressive storms that can travel long distances. DECODE researchers used a comprehensive set of observations—from radar and satellite to balloon sondes to flyovers—to examine this phenomenon. Their mission was to understand how the boundary forms and under what circumstances it might create unusual weather.

On average, in the three months of summer each year from 2012 to 2016, 60 days produced a boundary, and 44 percent of those boundaries resulted in convective initiation (CI), noted Zhiyong Meng, of Peking University, in her July 20 presentation during Session 16 of 32WAF/20Meso/28NWP. The DECODE field experiment itself lasted 36 days in 2022, from 5 July to 9 August. With two field stations located on the oasis side, and four on the desert side, the teams were able to observe 23 boundaries and 11 occurrences of deep convection initiation, and even one case of a tornado.

Yipeng Huang, of Xiamen Key Laboratory of Straits Meteorology, outlined the most common conditions leading to a boundary/CI in a 21 July presentation. The researchers found that a boundary is most likely on warm summer days, when synoptic forcing is relatively weak, with dominant southerly winds opposing the oasis breeze, and a temperature over the desert that is apparently warmer than over the oasis. They found that along the boundary line between the two masses of air, convection initiation may occur when enough moist air advects north at the west edge of the subtropical high, moves out over the dry desert, and converges with a cool oasis breeze in an environment with large enough instability. Hongjun Liu of Peking University presented the mechanism for this process in a case study on 21 July.

*Diagram of boundary formation and convection initiation near Hetao Irrigation District. Image courtesy of Zhiyong Meng.*

Meng described “The most beautiful case, on July 29 [2022, when] the boundary produced a CI and the storm became very strong; it actually produced five-millimeter hail in the eastern part of the oasis.” They were also able to observe another storm as it split into two separate supercells. On July 25, a preexisting storm that passed over the area dissipated somewhat, likely due to sinking air over the oasis, then re-initiated strongly once it reached the boundary/convergence line over the desert. On occasion, the boundary would extend over the oasis and strongly increase the precipitation there.

In the presentation immediately following Meng’s, Murong Zhang of Xiamen University noted that the team’s real-time forecasts were able to predict the formation of the boundary line in 21 out of 23 cases, although predicting convection initiation was more difficult. They were only able to predict 6 out of 11 CIs, as the numerical model tended to over-predict surface temperature, but under-predict moisture. The observations obtained from DECODE have been used to effectively improve the surface heat flux over the irrigated area, as shown in a presentation by Xuelei Wang of Peking University on the first day of the conference. You can see more from the DECODE team in this video created as part of the project:

With researchers from many institutions* participating, DECODE is an epic undertaking to study a unique natural phenomenon. As field research pioneer Prof. Edward Zipser of Utah University noted after Zhang’s talk, it’s “a program that we want to hear more about.”

Building Community to Solve the Big Challenges in Weather, Water, and Climate

October 27, 2023

Some thoughts following the AMS Summer Community Meeting

By Isabella Herrera, AMS Policy Program

How can the weather, water, and climate enterprise better collect and use socioeconomic data to keep vulnerable populations safe from environmental hazards? What are the challenges of establishing a national network to monitor the planetary boundary layer? How are we dealing with radio frequency interference that hampers weather monitoring and forecasting? These questions can be answered only through collaborative efforts across the weather, water, and climate enterprise. One of the most important roles of the American Meteorological Society is to convene meetings where WWC professionals can delve into these vital topics.

The AMS Summer Community Meeting is a perfect example of that convening ability in action. Professionals from the private, public, and academic sectors come together, both in person and virtually, to share their visions for the future of the weather, water, and climate enterprise(s).

Having now worked for the American Meteorological Society for just over a year, I was very excited to have the opportunity to attend the AMS Summer Community Meeting for the first time in Minneapolis this August. At this two-day conference, attendees immersed themselves in discussions about current challenges, opportunities, and efforts throughout the AMS community and related fields.

A conduit for collaboration

As an in-person attendee this year, one thing that struck me was how the Summer Community Meeting served as a conduit for conversation. Information and ideas flowed easily between the various presenters, panelists, and the audience. For example, sessions focused on commercial radar services and NOAA research allowed the public and private sectors to share their perspectives. They presented pressing issues, opportunities for potential collaborations, and the work currently being done across the enterprise.

*Summer Community Meeting attendees listen to a discussion of NOAA’s Next Generation Weather Radar (NEXRAD) system.*

Some of the topics covered at this meeting included: updates on national policy; the NOAA Precipitation Prediction Grand Challenge; pressing issues in radar and forecasting, such as moving the national radar network beyond the WSR-88Ds; and the operations of the National Severe Storms Laboratory. My colleagues from AMS discussed the new and ongoing initiatives of the AMS Policy Program, such as: enhancing the effectiveness and potential of the weather enterprise over the next decade and beyond (see page 823 of the October issue of BAMS), the 2024 Summer Policy Colloquium, and the role of the AMS in enabling the future of both the climate and ocean enterprises.

Hurricane prediction gets personal

I was fascinated by some of the discussions about extreme weather and the increasing frequency of Billion-Dollar Weather and Climate Disasters. Attendees from the National Weather Service highlighted the widespread efforts to improve our forecasting and modeling of extreme weather events.

Discussions about major tropical storms particularly resonated for me, especially with Hurricane Idalia making landfall in Florida during the Meeting. I was born, raised, and currently reside in the Sunshine State, so I’m well-attuned to hurricane season and planning for impending storms. Hurricane Idalia is a perfect example of how advancements in hurricane models and forecasting have allowed meteorologists and WWC professionals to more accurately predict and communicate extreme weather hazards (such as the rapid intensification of the storm right before it made landfall), thus saving lives. I was able to witness some of this behind-the-scenes work.

Compared with being at home refreshing the National Hurricane Center’s webpage and listening to advisories on the local news, as I had during previous hurricane seasons, this was an invaluable experience.

Reunions

I was delighted to see fellow AMS Summer Policy Colloquium alum Larry Hopper presenting on current and emerging radar technologies as part of a Panel Discussion on Weather Radar Research. Reconnecting with Colloquium alumni is something that I’m looking forward to at the AMS Annual Meeting in January, and although the dates have yet to be announced for next year’s Summer Community Meeting, I’m already excited to hear about the initiatives across the WWC enterprise for 2024.

I saw so many others reunite with their colleagues, too (from graduate school, from years of working in the field together, or from previous AMS meetings). It reminded me that, in addition to creating connections, collaborations, and conversation across the weather, water, and climate enterprise, the AMS has another integral part to play in this space: building community.

“Once in a Generation”: The 2022 Buffalo Blizzard

October 12, 2023

A Research Spotlight from 32WAF/28NWP/20Meso

On 23 December, 2022, David Zaff of the National Weather Service’s Buffalo office walked out into a blank white world of howling wind. He headed to his car to get supplies, knowing there was no way to get home. He and his coworkers were trapped at the office, in the middle of one of the most deadly and disastrous blizzards Buffalo has ever seen.

Video by David Zaff, showing whiteout conditions outside NWS Buffalo office, December 23, 2022.

At the height of the 2022 holiday travel season, the four-day blizzard and lake-effect snow event knocked out power for more than 100,000 people, paralyzed emergency services and holiday travel, and left at least 47 dead. New York Governor Kathy Hochul described it as “the most devastating storm in Buffalo’s long, storied history.” Yet days earlier, Zaff and colleagues encountered skepticism from the public as they worked to warn the region.

Presenting at the J3 Joint Session at the 32nd Conference on Weather Analysis and Forecasting, the 20th Conference on Mesoscale Processes, and the 28th Conference on Numerical Weather Prediction, Zaff talked about the disaster and how the NWS countered accusations of hyperbole to get the word out.

Sounding the Alarm

The December 2022 snow was shocking, but not surprising. The pattern was easy enough to recognize, even 7–10 days earlier: a large high-pressure ridge forming over the western U.S., with a major trough in the east. “We knew something big was coming,” said Zaff. Five days before the storm, even low-resolution models suggested a major event. Four days ahead, the NWS started ringing the alarm bell. “We started saying, ‘A powerful storm will impact the region heading into the holiday weekend.’”

Three days out, the NWS issued an unusually emphatic Area Forecast Discussion (AFD):

“Some of the parameters of this intense storm are forecast to be climatologically ‘off the charts’ … One could certainly describe this storm system as a once in a generation type of event.”
NWS Lead Forecaster Robert Hamilton, Tuesday, December 20, 2022

That caused a stir, but many on social media dismissed it as hype. “People started saying, ‘There goes the weather service again,’” says Zaff.

He tried to find a way to show the science graphically, highlighting the forecast as “‘outside’ the climatology” for the time of year.

The graphic and its accompanying description got attention. By then, NWS Buffalo was communicating in earnest, including on social media. A tweet with a text-filled screengrab of the Winter Weather Message received 485,000 views. “A picture is worth a thousand words,” Zaff said, “except when people actually read the words, and see how impressive this event might be.”

Surviving the Storm

Before noon on 23 December, visibility dropped to near zero, and it remained that way until around midnight on 25 December. 500 Millibar heights were “extraordinary” as the pressure trough moved into the Ohio Valley, and surface-level pressure was similarly unbelievable. A top wind speed of 79 mph was measured in downtown Buffalo at 10:10 a.m. on the 23^rd, and winds in the 60–70 mph range lasted for 12 hours. “[It was] just an incredible bomb cyclone,” Zaff said. “An incredible storm.”

Zaff and some colleagues slept at the office; others attempted to drive in whiteout conditions using GPS alone, while some got stuck in drifts near the office and had to leave their cars to hike the rest of the way. Meanwhile, firefighters and airport employees worked to rescue motorists trapped nearby.

On December 24, the City of Buffalo issued “the scariest tweet I’ve ever seen,” said Zaff. The tweet stated that there were “no emergency services available” for Buffalo and numerous other towns.

“We knew by this time that there were fatalities occurring,” Zaff said. “And it just got worse and worse.”

Blizzard conditions lasted a full 37 hours–and lake effect snow wouldn’t stop for another two days. Three power substations shut down, frozen solid. Hundreds of power poles fell, and a significant percentage of locals were without power during the storm’s peak (some for days afterwards).

The 47 fatalities included people stranded outside, others who died from hypothermia in their homes, and some deaths due to delayed EMS response, according to Erie County. Hundreds of motorists were stranded on roadways during the storm. The Buffalo Niagara International Airport, with a proud legacy of operating under even the most horrific conditions, was closed for six days.

Zaff didn’t return home until late afternoon on the 25th, 18 hours after official blizzard conditions were over and having clocked 50+ hours at the office. On the drive, he saw iced-over buildings and trucks buried in snowdrifts. “It reminded me of [the movie] The Day After Tomorrow. … The impacts were tremendous.”

In his AMS presentation, Zaff compared the 2022 event to disastrous storms in 1977 (20+ fatalities, 69 mph winds, only 12” of snow yet drifts swallowed homes) and 1985 (5 fatalities, 53 mph winds, 33” snow), as well as the “Great Christmas Storm” of 1878, one of the first well-documented lake effect snow events, though lake-effect processes weren’t understood at the time. “This will likely be the storm of comparison now,” he says. “Once-in-a-generation” turned out to be right.

Future Lessons

Moving forward, said Zaff later, “Our intention is to further our relations with our Core Partners, including elected officials, emergency management, and the media [and] provide more probabilistic information that supports our ongoing Impact Decision Support Services. We hope to improve our outreach as well, instilling more confidence with the public.”

NWS will continue to provide improved decision support for partners, which may lead to more proactive road and school closures that could save lives in the future.

CalFiDE: Observing Large-Scale Fires from the Air and the Road

August 22, 2023

A Research Spotlight from the 14^th Annual Fire and Forest Meteorology Symposium, 2–4 May, 2023

Through the smoke of record-setting Canadian wildfires–which continue to burn millions of acres in the north–the importance of understanding huge, landscape-scale fires has never been clearer. In a 4 May presentation in the ninth session of the 14^th Fire and Forest Meteorology Symposium, Brian Carroll discussed recent efforts to gather scientific observations on these types of landscape-scale wildfires in California and Oregon through CalFiDE, the California Fire Dynamics Experiment. His team looked at the behaviors of these fires and the winds they create and interact with, as well as the impacts of smoke plumes on air quality.

Field observations of wildfires this large are very rare. The CalFiDE team (including scientists from NOAA, CIRES, San Jose State University, the University of Nevada Reno, and NASA) used airborne and ground-based vehicles and a satellite to take measurements of five fires in August–September 2022. That included the Mosquito Fire, the largest in California that year, which burned more than 76,000 acres and prompted evacuation orders for 11,000 people.

Carroll described the difficult and potentially dangerous process of conducting continuous observations of huge fires, without getting in the way of firefighters and emergency managers.

“There’s an aircraft exclusion zone that’s dedicated for the firefighters,” he notes. “The pilots have that information and avoid those areas but the pilots’ own decisions to keep our aircraft safe against the strong fire-generated winds and smoke are also a big driver. Even at a safe distance from the strong updraft produced by the fire, the wind convergence into the smoke column had to be compensated for by angling the plane away.”

They were aided by state-of-the-art mobile Doppler lidar systems that allowed them to map air and fire behaviors over large distances in complicated terrain. “There are few lidars in the world capable of making these wind measurements while moving, and that mobility is important when dealing with wildfires that are constantly evolving,” Carroll says. “The lidars also provide real-time information on the winds and location of smoke layers, and we use that information to optimize sampling patterns and target layers for sampling trace gases.”

The CalFiDE team conducted surveys with a NOAA Twin Otter airplane, using Doppler lidar, infrared imaging, and trace gas measurements. They also drove an instrumented pickup truck (known as PUMAS, the Pick-Up-based Mobile Atmospheric Sounder) on the outskirts of the fire with additional Doppler lidar and temperature measurements, getting a 3-D picture of the winds above the truck as they drove. Meanwhile, the Multi-angle Imaging SpectroRadiometer (MISR) instrument aboard NASA’s Terra satellite provided a broad swath of smoke distribution information from space.

Above image: Fires observed during the 2022 CalFiDE campaign. Aircraft bases of operation with 1-hour flight range ring are shown in black, and platforms involved are on the right. The Twin Otter and PUMAS both had scanning Doppler lidars capable of profiling winds while underway.

The airborne lidar provided cross-sections of fire updraft cores (areas of hot, rising air) and smoke plume motions, complemented by the infrared imagery capturing the fire’s shape and evolving intensity. These are some of the first measurements of their kind, and will provide important ground-truth comparisons for fire and air quality modeling.

Plots of airborne Doppler lidar measurements show a side-view cross section of smoke plumes over fire. These are vertical profiles of upward/downward winds (vertical velocity) from the Mosquito Fire on 8 September, 2022, taken at 7:03 pm (top) and and 7:17 pm (bottom). Darker red indicates faster upward air movement, and the black lines correspond to the smoke plume. Black arrows show wind speed and direction at different heights. Colored dots show the altitude of the ground surface and the “brightness temperature” (intensity of the fire heat) at each location based on longwave infrared imaging.

PUMAS observations also allowed the team to generate a high-resolution picture of smoke behavior in nearby areas—for example, the ways smoke lingered in valleys during calm conditions, and how rapidly air quality improved when sea breezes disrupted the smoke layer.

“Driving around these local valleys, in a few kilometers you could have a huge change in how much smoke there was, and a large change in temperature. And there’s a major change in boundary layer dynamics as you move in and out of those regions.”

Brian Carroll, Research Scientist at CIRES/NOAA

PUMAS data showing smoke-filled valleys. Very high concentrations of smoke in the morning, confined in the lowest 500 meters (top panel), transitioned to cleaner air (bottom panel) with the introduction of a sea breeze that traveled through the valleys. Data curtains (colored vertical stripes) depict lidar attenuated backscatter, which correlates with smoke concentration, along a 56 km driving route. Arrows show wind direction, with size and color indicating wind speed.

“The West Coast of the United States has experienced terrible fire seasons recently, with smoke impacting the lives of millions and fires themselves displacing many others. People across the U.S. and Canada have gained additional insight this year into what that’s like. We need more comprehensive information about how these fires grow, how the smoke moves, and the atmospheric conditions that interact with the fires, as we face a future that will likely see even more extreme fire seasons. The CalFiDE team’s efforts will help meet those needs,” Carroll says.

An article providing an overview of CalFiDE has been submitted for publication in the Bulletin of the American Meteorological Society.

About 14Fire

Meteorology and wildfires are intimately interconnected—and wildfires are becoming increasingly severe and frequent in many parts of the United States. From local residents and firefighters on the ground to planners and insurers, to people hundreds of miles away breathing wind-driven smoke, society relies on our ever-improving ability to understand and forecast fires and the related atmospheric conditions. The American Meteorological Society’s 14^th Fire and Forest Meteorology Symposium brought together researchers and fire managers to discuss the latest science. All conference presentations are now publicly available.

New data from the past ten years reveal increased prominence of freshwater floods and indirect fatalities in hurricane deaths

Guest post by Dr. Michael Brennan, Director, National Hurricane Center; Daniel Brown, Warning Coordination Meteorologist, National Hurricane Center; and Leah Pope, Hydrologist, Northwest River Forecast Center

The National Hurricane Center’s mission to “save lives and mitigate property loss” is not just achieved by issuing effective watches, warnings, and forecasts of tropical cyclones. We also spend a large portion of the “offseason” educating the public, emergency managers, and our media partners about the risks that tropical cyclones (TCs), including hurricanes, pose to life and property in the United States. Those include natural hazards such as storm surge, wind, and rip currents, and also includes dangerous conditions in the aftermath of a landfalling tropical cyclone, which may lead to “indirect” fatalities. These are deaths which are not directly due to the forces of the storm, but which would not otherwise have occurred. NHC routinely compiles and assesses TC-related information through vehicles such as our Tropical Cyclone Reports (TCRs). Data from the most recent decade reveal that fatality trends may be changing.

Note: The fatality data presented here do not include any fatalities from Hurricane Maria in Puerto Rico, since there was no specific, definitive cause provided for those deaths.

Direct Fatalities

Previous studies by Rappaport (2014) and Rappaport and Blanchard (2016) summarized direct and indirect fatality data from Atlantic basin tropical cyclones in the United States for the 50-year period 1963–2012. During that period, nearly 9 out of 10 tropical cyclone-related direct deaths in the United States were due to water. Storm surge was responsible for nearly half (49%) of the direct deaths, and over one-quarter (27%) were due to rainfall-induced freshwater flooding.

In response, the National Weather Service (NWS) and NHC worked to improve outreach, education, and communication of storm surge and rainfall hazards. We introduced new real-time storm surge maps in 2014, and in 2017 introduced a storm surge watch/warning that highlights the risk of life-threatening storm surge inundation.

New Data Suggest Changing Trends

Since 2012, the United States has experienced 21 hurricane landfalls, including 8 major hurricanes, and more than 20 tropical storm landfalls. Eighteen of these hurricane landfalls, including all of the major hurricanes, occurred during 2017–22 after a relatively quiet period. Given the significant number of tropical cyclone landfalls in recent years, and increased deployment of warnings around the storm surge hazard, NHC examined and compared fatality data from the most recent 10-year period (2013–22) to the earlier studies.

Hazard	% of direct fatalities from this cause (1963–2012)	% of direct fatalities from this cause (2013–2022)
Storm Surge	49%	11%
Freshwater Flooding	27%	57%
Wind	8%	12%
Surf/Rip Currents	6%	15%
Offshore Marine Incidents	6%	3%
Tornadoes	3%	2%
Other	1%	1%

Note: Due to rounding, numbers may not add up to 100%.

During the most recent 10-year period in the United States, about 57% of direct tropical cyclone deaths were due to drowning from freshwater (rainfall) flooding. Surf and rip current fatalities have become an increasing threat, making up about 15% of direct fatalities in the past decade. These fatalities often occur one or two at a time from distant storms hundreds of miles offshore. Florida, North Carolina, and New Jersey experienced the highest number of TC-related surf and rip current fatalities. Storm surge and wind-related deaths account for 11% and 12% of the direct fatalities, respectively.

Every hurricane is different, however. Hurricane Harvey in 2017 had the largest number of direct deaths—68, 65 of which were due to freshwater flooding in Texas—in the past decade. Hurricane Ian (2022) was the second deadliest with 66 direct fatalities, 41 of which were due to storm surge in Florida. More than 65% of those who died from direct causes were men, with about 60% of the victims over the age of 60.

Indirect Causes

The recent study revealed that over the past 10 years there has been nearly an equal number of indirect deaths as direct fatalities. Indirect fatalities are due to a wide range of causes, including traffic accidents (16%), preparation/cleanup accidents (15%), carbon monoxide poisoning (12%), lack of medical care (11%), power problem/electrocution (11%), post-storm heat deaths (9%), unknown causes (9%), cardiac-related deaths (7%), and evacuation-related deaths (5%).

The largest number of indirect deaths in the past decade occurred in association with Hurricanes Ian (90), Irma (82), Michael (43), Harvey (35), and Laura (34). Most (75%) of the indirect deaths are associated with major hurricane landfalls, which leave communities very vulnerable and often with long-duration, widespread power outages. More than half (57%) of the victims were over the age of 60. Younger victims tended to die in vehicle accidents; for older victims, medical-related issues, heat, evacuation, and other accidents were more likely causes of death.

Improving Warnings and Public Understanding

The results of these most recent studies have led the NWS and NHC to increase messaging on the hazards and causes of both direct and indirect fatalities. We continue to highlight rainfall flooding and storm surge risk through the Weather Prediction Center’s Excessive Rainfall Outlook, Flood Warnings from local NWS offices, and increased emphasis on the Storm Surge Warning. These warnings are the loudest “bells” that the NWS can ring during life-threatening flooding. We encourage our media and emergency management partners to work with us to encourage timely public response and personal preparedness ahead of these threats.

Additionally, with the increased percentage of rip current fatalities associated with high surf and swells from distant hurricanes, the NWS has created new infographics to explain this deadly beach hazard, and is working on graphics to better highlight the threat in real time.

During the highly impactful 2020 hurricane season in the United States, there were more fatalities associated with carbon monoxide poisoning from the improper use of generators than there were from storm surge. After that season, NHC and the NWS developed infographics and worked with media and emergency management partners to highlight that threat. While it is difficult to determine the effectiveness of that messaging, it is encouraging to know that there were no carbon monoxide related-fatalities in the aftermath of Hurricane Ian in 2022 in Florida, despite its devastating impacts and widespread power outages in that state.

NHC relies on relationships with media, emergency management partners, and the entire weather enterprise to help reach the public before, during, and after tropical cyclone threats. These efforts undoubtedly increase awareness, encourage preparation, and save lives. We hope to continue to improve our messaging and understanding of the threats and causes of injuries and fatalities to better meet our collective mission.

Lessons from Longtime Broadcast Meteorologists

In the third of three posts celebrating the 50th Conference on Broadcast Meteorology, we asked longtime broadcast meteorologists about what it means to do what they do, and their advice for others in the field.

What are some historic weather events you’ve covered, and what did you learn?

“It’s easy to joke with the news anchors and talk about a beautiful 75-degree day. But when severe or extreme weather approaches, the true essence of a broadcast meteorologist’s role is public safety. The first two weeks of 1999 was one of the harshest stretches of winter weather the Detroit area has ever seen, and I was out reporting live [when] people were struggling to get to work… [It was so cold] that roads salted the previous afternoon had an overnight refreeze … I cautioned people [that] if they were the first car at a stop light and it turned green, to pause a moment to make sure that nobody was skidding through the intersection before proceeding through. Later in the day, a viewer e-mailed to tell me that I had directly saved her life … that she was stopped at a light and, when it turned green, was about to hit the accelerator like normal, then remembered what I had said. She put her foot back on the brake. At that moment, a panel truck came barreling across the intersection from the left. Had she proceeded without pausing, she likely would have been broadsided and killed.

No matter if it’s a severe winter storm, thunderstorm, tornado, hurricane, flash flood, or any other significant natural hazard, our job as broadcast meteorologists is to take the viewers by the hand and help them make informed decisions that could save their lives. Nobody [else] in broadcast media has this responsibility on a daily basis. And there is no greater compliment than when somebody says ‘you saved my life.’”
Paul Gross, AMS Fellow, CCM and CBM

“There have been many historic weather events from Hurricanes Andrew, Fran, and Floyd to numerous tornado outbreaks in Middle Tennessee. The one event that stands out the most is the Great Flood of 2010 that impacted Tennessee with record rainfall totals and historic flooding. Interstates became raging rivers; neighborhoods were submerged in water and even downtown Nashville was flooded with several feet of water coving streets. Over 30 people lost their lives.

From all these events I have learned how much people in my community rely on me for critical information to help them prepare, survive and recover. It’s so important for me to deliver that information in a calm but urgent tone.”
Lisa Spencer, Chief Meteorologist, News4, Nashville, Tennessee

“The Barneveld F-5 Tornado in June 1984 was an early event that I covered. Nine people lost their lives in that terrible storm and it hit at 1 a.m. It had a major impact on me in terms of staying late into the night if necessary to issue warnings. In my St. Louis years, there were often times that I would stay after the late news to cover thunderstorm complexes and not get home until 5 a.m. In Denver, our thunderstorms tend to be in the afternoon and evening – but I have spent many nights here covering blizzards!

Most recently, we had a massive wildfire in December 2021 that destroyed nearly 6,000 buildings just south of Boulder, Colorado. The Marshall Fire was a huge firestorm caused in part by very warm and dry weather – related to climate change. I try to incorporate the climate change connection into my weather reports as often as possible.”

What does being a Certified Broadcast Meteorologist mean to you?

“I find great value in the CBM program. I served on the committee to develop the seal program. In addition, I also helped develop the first test and testing guide.

When I see that someone has earned the CBM seal, I know that they have gone through a rigorous test to demonstrate their expertise in the field. Additionally, I am confident in their communication skills knowing their work has been reviewed by a group of experienced peers. CBM seal holders have gone the extra mile to make sure they are equipped to deliver critical weather and science information to their communities.”
Lisa Spencer, Chief Meteorologist, News4, Nashville, Tennessee

“I am CBM number 50, so I have had the designation for a while. The CBM represents the highest level of certification that the AMS can provide to a broadcast meteorologist and it should be held with high esteem. It takes a lot of work to achieve and should merit respect from the TV stations, networks and – most important – the viewer. As CBMs, we have a unique opportunity and responsibility to educate our viewers about weather, science and climate change.”
Mike Nelson, Denver7 Chief Meteorologist, KMGH, Denver, Colorado

What are some lessons you’d like to share with other broadcasters?

“Be active in the community, visit schools, answer all your email, educate the public about climate change. Also, the years go by faster than you will imagine – be sure to plan for your financial future as this business is not getting easier and will never pay as well as it did during my career (sorry)!”
Mike Nelson, Denver7 Chief Meteorologist, KMGH, Denver, Colorado

“Be yourself, be humble, stay focused, set goals and have fun!”

“From my over-35-year career as a broadcast meteorologist, I have learned the one thing you can count on is change… change in management at all levels, change in responsibilities, and change in the technology and the way we present the weather. But with all those changes we have to remember what we are there for… to serve our communities with the most accurate, informative weather information especially in critical times. When someone recognizes you in public and acts like they know you personally… that’s a good thing. You have made a connection and are welcomed in their home, on the TV or whatever device they are using to watch you. I try to always be gracious.”

Celebrating the 50th Conference on Broadcast Meteorology

We’re back with the second of three posts highlighting memories from longtime broadcast meteorologists, as we celebrate last month’s 50th Conference on Broadcast Meteorology! Today’s post highlights how the field of broadcast meteorology has evolved over the decades since these meteorologists started out.

“If you told me in 1983 at the beginning of my career that, forty years later, I would hold a portable little computer in my hand that dwarfs the computing capacity of what was in the spacecraft that took astronauts to the moon, watch live radar on that little computer, and then send personal messages with those radar images and warnings to large groups people in seconds, I would have laughed at you. Everybody talks about model and radar improvements that have occurred during this time period, but the development of instantaneous communication of weather information is mind-blowing and has truly benefited the public.”
Paul Gross, AMS Fellow, CCM and CBM

“During my first internship at WMC in Memphis in the early 1980s, the station was still using a magnetic surface map during their weathercast. Of course, now we use augmented reality graphics. Forecasting in the 1980s when I started my career consisted of large printed surface maps and spaghetti charts; we would use colored pencils to make analysis. Now everything is available online and from multiple sources.

“When I first started attending AMS Broadcast Conferences in the early 1990s, Bryan Busby (KMBC-TV) and I had a running joke where we greeted each other as “the other Black guy,” because we were the only two African-Americans there. I am thrilled to see the growth in diversity in our field and our conferences over the decades, to where we can’t say that anymore!”

“I can remember having 5 p.m., 6 p.m., and 10 p.m. newscasts. I was responsible for one 3 ½-minute weathercast during each news show and maybe updating a phone line forecast. Now, I have a 3 p.m., 4 p.m., 5 p.m., 6 p.m., 6:30 p.m., and 10 p.m. newscasts with not only a generally 3-minute weathercast, but usually a first weather and teases. In addition, I am responsible for updating weather forecasts on a phone line, for radio, multiple social media platforms, the website and streaming service.”

“I started in Seattle in 1971… the satellite images used on the air at KING-TV were single 4×5-inch B&W Polaroids taken at the local NWS office, a 10-minute drive downtown.

Stumping Bryan Gumbel and Jane Pauley with weather science on NBC’s TODAY in the ’80s was always fun, especially demonstrating the shape of rain drops by creating air bubbles in a 6-foot-tall clear plastic tube of Karo syrup (a sticky clean-up.)”
Joe Witte, Climate Outreach Specialist, Aquent, Pasadena, California

“I started my career at WKOW-TV in Madison, WI in 1976. … My first job was to erase the weather boards and help draw weather maps that would be used [by Terry Kelly, President of Weather Central, in his] weather reports. These maps were hand-drawn on lightweight cardboard and were then taped to the wall of the studio in a series of 5-6 maps. The cameraman (there were few women camera operators back then) would pan from left to right across the series of maps to help tell the story. If the masking tape let go, the map would fall to the floor – the viewers were certainly startled to see that! Making these maps took many hours and it was nearly impossible to change the map if the weather changed.

In 1979, Terry Kelly teamed up with some computer scientists at The UW Space Science and Engineering Department to create the Apple II Weather System which became one of the first TV Weather Computer Systems. … My job in the late 1970s through the mid-1980s was to travel around the country to install the various generations of these computers and train the meteorologists in this new technology. I installed over 50 units during this time and had the honor of meeting and training many of the legends of our industry such as Al Roker, Don Kent, Gary England, Bruce Schwoegler, Bob Copeland, Harry Volkman, Dick Albert, George Winterling, and Valerie Collins. It was truly an amazing time as the computer systems were rapidly changing and the competition between computer companies was intense!”

“[My] first TV job was with the old WGAN-TV in Portland, Maine, as the first meteorologist on staff… [It] entailed washing down the regional and national weather maps–floor-to-ceiling and made of linoleum, and covered with the tempera-marker info from the night before. Mop-and-bucket work was just part of the shift. Paper weather maps, magnetic suns and moons, and air-brushed clouds followed before actual digital graphics arrived.

As a broadcast meteorologist back then, one had to be proficient in more than forecasting. Changing out helixes in the fax machine, repairing the teletype (without sending 72 volts through your body), changing toner in the satellite receiver, and unending paper cuts were all part of your day.”
