This year’s AMS Annual Meeting provided no shortage of memorable presentations. The focus on 2017’s hurricanes in particular yielded some of the most memorable moments, and now you can listen (again, or for the first time) for yourself. Recorded presentations are being uploaded gradually to the AMS meeting program site.

Richard Alley’s speech at the Presidential Forum was the first to go online, here including AMS President Roger Wakimoto’s introduction as well as questions from the audience:

Here’s a portion of Dr. Alley’s memorable riff on our semi-aware relationship to the science and technology we carry around in our pockets every day:

I’m a Newtonian physicist. I didn’t take quantum, I didn’t take relativity. But my understand is that the nice lady in the (cell) phone using the GPS is using both general and special relativity. Because down here, she is deeper in Earth’s gravity well and she is moving slower than the clocks on the satellite. And the correction from relativity is about 10 km a day. And she can do 10 km pretty easily. Which means if she didn’t have relativity, she would get lost in about two minutes. And that’s … We get where we’re going not only because of quantum mechanics but also because of Einstein. And, no, she will not fall for you because she’s canoodling with Einstein in the phone here.

But you know how these things work. Right? … I’ve been working on ice since 1977, the summer after my freshman year. My teachers, in geology and other things, I think if you were to ask them what is the most useless and esoteric science you can think of, they might have said relativity and quantum mechanics. And you’ve got relativity and quantum mechanics in your phone, in your pocket, and you can’t really think of living the life you now live if we didn’t understand relativity and quantum mechanics….

Climate science is not this new-fangled stuff you’ve got in your cell phone … it’s been with us for a long time. But I can tell you, and some of you out there know this as well, that there are people—good people, neighbors, people who pay our salaries—who will pull out their cell phone and send me a note saying, ‘You’re an evil liar. You should be fired.’ They go to my president and try to get me fired. Because I’m talking about this global nonsense. ‘These scientists are just trying to take away our pickup trucks.’ And they do it with a cell phone. And they are, I think, all across the board, good people. Some of them have been misled. And that’s something we have to come back to.

Also online now are the talks from the web-streamed Presidential Town Hall on the hurricane season.  Well worth a listen while you’re waiting for more talks to appear online, like this reaction to forecasting Hurricane Irma, from NBC-6 Miami Chief Meteorologist John Toohey-Morales:

In South Florida I’m known as the non-alarmist guy. I mean if you want a just-the-facts-and-he’s-not-at-all-that-excited-about-this-tropical-cyclone guy, I’m your person … But with Hurricane Irma … on Friday night … National Weather Service Key West … about to go into full-Katrina mode: catastrophic, life threatening, and those types of messages were about to go out … what does the non-alarmist guy do? (Plays video of his TV broadcast that Friday night.) ‘If you’re sitting on a Florida Key right now—What the heck are ya doing? Get out! Now!’

Or this zinger from FEMA’s Tony Robinson, while talking about Hurricane Harvey:

Working with our counterparts in the state of Louisiana a guy said, ‘I finally figured out your flood codes on when I should have flood insurance.’ And I said, ‘Oh, yeah? What’s that?’ He said, ‘Your driver’s license says Louisiana, you aughta have flood insurance.’ That’s a public service announcement right there. There’s 144 days to the start of the 2018 hurricane season.”

But it was Ada Monzon, WIPR TV/WKAQ Radio, San Juan, who drew a rare standing ovation after her heartfelt presentation on Hurricane Maria:

And I can tell you, that in my 30 years as a meteorologist in Puerto Rico, even going through Hugo and Georges and more than 10 other tropical storms … (I’m sorry) … For the first time in my life I was afraid. Not because of the wind or the storm surge or the rain. I was afraid [for] the future of Puerto Rico. … Still to this day there are great discrepancies on how many people died in Puerto Rico because of Maria. By government information, there were 64 dead. Our other entities have informed … of more than 1,000 dead. … The response and recovery efforts have been very slow and complicated. More than three months after the hurricane, near 45% of the island is still without power. Many are suffering. More than 100,000 people have left the island in the last three months, to Florida, New York, Texas. … Enduring two major hurricanes has been hard. But at the same time it has served a vast lesson to all our society: We need to find a way of living with natural disasters and other potential catastrophic events and we need to work harder as meteorologists and scientists to educate our public through all means of communication, especially social media.

So many conversations at the 2018 AMS Annual Meeting started–and ended–on the same note, and Dakota Smith captures it just right in his “Weather Nerds Assemble” vlog:

Communication is a huge aspect in this field….If a forecast is a hundred percent accurate, but no one understands it, it’s not a useful forecast. That in a nutshell was what this meeting was about.

According to Smith, all that geeked out conversation amongst 4,200 weather, water, and climate nerds added up to at least these four lessons:

  1. The future is bright: “I talked with so many intelligent, bright, passionate students who are bound to make an impact on our community. Keep up the grind!”
  2. Meteorologists are incredibly strong: The communications workshop reflecting on the experience of Harvey, Irma, and Maria showed that  “meteorologists across the country used…love and passion to fuel them through this relentless hurricane season.”
  3. Austin has incredible BBQ.
  4. Meteorologists are awesome. “I already knew this before…we love weather, and we love science!”

The last two are obvious, right? The first two make our day. Share your own take-away points; meanwhile, you owe yourself the injection of enthusiasm–just in case you got lost in the trees since returning home:

Dear AMS Community,

I am delighted to send this letter to you after the wonderful Annual Meeting in Austin. You told us that the Presidential Forum with Richard Alley and the Presidential Town Hall on the recent hurricane season were the highlights of the week (both can be viewed online) and I am glad that our efforts to arrange for these two events were well-received. The latter was possible owing to our breadth as a scientific and professional society. It allowed us to assemble a panel of experts from the university and broadcast communities, NWS, FEMA, and Flood Control District that could tell a story that was quite engaging.

I was honored to have completed President Matt Parker’s vision for the Annual Meeting. I believe that he would have been very pleased with the program. Of course, the AMS staff, Executive Committee, and Council are an amazing and supportive group to work with and I owe them a deep debt of gratitude for supporting me during the past year.

I wanted to take this opportunity to highlight a couple of priorities that I will be working on in the coming months. I am deeply committed to diversity, equity, and inclusion. The AMS supports a number of programs that illustrate their commitment to diversity. However, I believe it is time to step back and review diversity, equity, and inclusion across AMS in a holistic manner and assess the collective effectiveness of its broadening participation efforts. What is our strategic vision on this important topic? With the support from Council, I appointed and charged a task force to review what the Society has accomplished to date in this area and to deliver a set of recommendations, including bold ones if necessary, to guide us as we rapidly approach our Centennial celebration. Susan Avery has kindly agreed to Chair this task force and I hope you contact her with your advice and suggestions.

There have been a number of events across the nation this past year that few of us could have predicted. The withdrawal from the Paris Climate Agreement (currently the only nation to do so), the March for Science, a proposed tax on graduate student tuition waivers, controversy at the EPA on the subject of membership on advisory committees and climate-related issues, and no Science Advisor for the Administration (the longest time this position has been left unfilled since it was created). These and other events beg the question whether AMS should alter the direction of its advocacy program or stay the course in this age of disruption. I have asked the Council to discuss this topic in the coming months so that we can define a path forward and communicate it clearly to all of you.

Finally, I would like to remind you of my vision for next year’s theme for the 2019 Annual Meeting in Phoenix, “Understanding and Building Resilience to Extreme Events by Being Interdisciplinary, International, and Inclusive.” It is the first time that extreme events, international and inclusive have been specifically highlighted in a theme and it is a timely subject owing to the natural disasters that impact our society and the need to build resilience. Xubin Zeng and Wen-Chau Lee are the overall program co-chairs and they are working with a great team that includes Julie Demuth, Rebecca Haacker-Santos, Sarah Jones, and Chris Schultz. The 2019 Annual Meeting will be the kickoff for a year-long celebration leading up the 2020 Centennial Meeting in Boston (will it snow or not??).

AMS has been a great organization that has supported me personally throughout my long scientific and professional career. In the bigger picture, AMS has endeavored to remain relevant and has adapted to change when necessary. Of course, AMS only exists because of you and the enormous number of hours that you volunteer to the organization. It is the primary reason that I know that the Society will continue to be strong and impactful for years to come. I hope to both meet and interact with as many of you as possible this year.

Roger M. Wakimoto, President, American Meteorological Society

The all-star panel comprising Monday’s special Town Hall Meeting on the 2017 hurricane season provided a riveting discussion of the science, communication, and impacts of Harvey, Irma, and Maria, highlighted by Ada Monzón’s emotional talk about the devastating effects Maria has had on Puerto Rico. The session created a buzz among #AMS2018 attendees.

The entire session has now been posted to the AMS YouTube channel, and you can also watch it below.

A good writer inevitably is also a good listener, always mining every conversation and interaction for the next gem that could be used in their work. Authors of AMS books are no exception, and this week in Austin you could be the person to provide one of them with a new idea or angle. A collection of authors will be reading from their works and participating in Q&A sessions with meeting attendees, providing you with an opportunity to discuss your interests with them and learn more about the writing process.

The events will take place on Tuesday and Wednesday at the AMS Resource Center in the Exhibit Hall. The Tuesday session will feature historical topics, with Bob Reeves exploring the history of long-range forecasting (4:oo PM), Jen Henderson speaking about Ted Fujita (4:20), Paul Menzel (4:40) and John Lewis (4:55) discussing Verner Suomi, and Lourdes Avilés looking back at the Great New England Hurricane (5:10).

Wednesday’s event will focus on science and society: Matt Barlow will speak about his forthcoming handbook for atmospheric dynamics (4:00 PM), Bob Henson will discuss climate change science and policy (4:20), and Bill Hooke (4:40) and Bill Gail (5:00) will consider the human relationship to climate.

A unique aspect of AMS books is the collegiality between the authors and their readers, and with this event we invite you to get to know some of them better and perhaps even help them with their craft. It’s the collaborative process at work!

From his book and PBS-TV series, “Earth: The Operator’s Manual,” to his renowned lectures at Penn State, Dr. Richard Alley is known for his humorous descriptions about serious science. Today he is the featured speaker as the 98th Annual AMS Annual Meeting begins in Austin, Texas.  Richard Alley

At the 18th AMS Presidential Forum  (4 pm, Ballroom D) Dr. Alley will use his unique brand of communication to discuss why communicating science to the public is no longer optional, but rather an imperative.

Dr. Alley, a renowned glaciologist and climate scientist, has a way with words. His colorful metaphors–like The Two-Mile Time Machine, the title his award-winning popular book about ice cores–put complex scientific issues into a comfortable perspective for perplexed audiences.

Last May, a couple months before a large piece of Antarctica’s Larson C ice shelf broke off,  Rolling Stone published an article about  potential catastrophic collapse of West Antarctica ice. In it, Dr. Alley explained that the Larson C breakage would not necessarily be an “end-of-the-world screaming hairy disaster conniption fit.”

And here, transcribed from a 2012 talk at the Smithsonian in which Dr. Alley explained the impact of burning fossil fuels and releasing CO2:

“You fill up a car and it’s a fairly big tank–you’re putting in a hundred pounds of gasoline. If you had to bring it home in gallon jugs it’d be a different world. But you drive off with it. And when you burn it — you add oxygen — and that makes CO2, and it goes out the tailpipe and you don’t see that 300 pounds per fill-up. Now, our students really get a kick out of it: at this point you say okay, suppose that our transportation system packaged the CO2 in a way we could see it … as horse ploppies…It’s a pound per mile driven for a typical vehicle in the fleet at this point. Ya know … Nnnnn — thffft. Nnnnn — thffft …. Our CO2 turned to the density of horse ploppies and spread over the roads of America would cover every road in America an inch deep every year. On average. Okay. In a decade … there are no joggers. We’d all be cross-country skiers. If we saw this it would be a completely different world. But it just drifts away and we don’t even see it.”

Sunday’s keynote talk at the Presidential Forum is likely to be just as, ummm, vivid. Simple but powerful. Definitely memorable.

It’s exactly the way Alley envisions engaging the public: by building the broad understanding necessary to make science actionable.

Perhaps no one thought that Game 5 of the World Series would end the way it did. It started with two of the game’s best pitchers facing off; a low-scoring duel seemed likely. But the hitters gained the upper hand. In the extra-inning slugfest the score climbed to 13-12.

If you started that game thinking every at-bat was a potential strike-out, and ended the game thinking every at-bat was a potential home run, then you’ll understand the findings about human expectations demonstrated in a new study in the AMS journal, Weather, Climate and Society. University of Washington researchers Margaret Grounds, Jared LeClerc, and Susan Joslyn shed light on the way our shifting expectations of flood frequency are based on recent events.

There are two common ways to quantify the likelihood of flooding. One is to give a “return period,” which tells (usually in years) how often a flood (or a greater magnitude flood) occurs in the historical record. It is an “average recurrence interval,” not a consistent pattern. The University of Washington authors note that a return period “almost invites this misinterpretation.” Too many people believe a 10-year return period means flooding happens on schedule, every 10 years, or that in every 10-year period, there will be one flood that meets or exceeds that water level.

Grounds et al. write:

This misinterpretation may create what we refer to as a ‘‘flood is due’’ effect. People may think that floods are more likely if a flood has not occurred in a span of time approaching the return period. Conversely, if a flood of that magnitude has just occurred, people may think the likelihood of another similar flood is less than what is intended by the expression.

In reality, floods that great can happen more frequently, or less frequently, over a short set of return periods. But in the long haul, the average time between floods of that magnitude or greater will be 10 years.

One might think the second common method of communicating about floods corrects for this problem. That is to give something like a batting average–a statistical probability that a flood exceeding a named threshold will occur in any given time period (usually a year). Based on the same numbers as a return period, this statistic helps convey the idea that, in any given year, a flood “might” occur. A 100-year return period would look like a 1% chance of a flood in any given year.

Grounds and her colleagues, however, found that people have variable expectations due to recent experience, despite the numbers. The “flood is due” effect is remarkably resilient.

The researchers surveyed 243 college students. Each student was shown just one of the three panels below of flood information for a hypothetical creek in the American West:

FloodBlog1

Each panel showed a different method of labeling flooding (panel A showed return periods; panel B percent chance of flooding; panel C had no quantification, marking levels A-B-C). The group for each panel was further subdivided into two subgroups: one subgroup was told a flood at the 10-year (or 10% or “A”) marker had occurred last year; the other subgroup was told such a flood last occurred 10 years ago. This fact affected the students’ assessment of the relative likelihood of another flood soon (they marked these assessments proportionally, on an unlabeled number line, which the researchers translated into probabilities).

Floodblog2

Notice, the group on the right, who did not deal with quantified risks (merely A-B-C), assessed a higher imminent threat if a flood had occurred last year. This “persistence” effect is as if a home run last inning made another home run seem more likely this inning. The opposite, “flood due” effect, appeared as expected for the group evaluating return period statistics. Participants dealing with percentage chances of floods were least prone to either effect.

This test gave participants a visualization, and also did not quantify water levels. Researchers realized both conditions might have thrown them a curve ball, skewing results, so the researchers tried another survey with 803 people (gathered through Amazon.com) to control test conditions. The same pattern emerged: an even bigger flood-is-due effect in the group evaluating return-period, a bigger persistence effect in the group with unquantified risks, and neither bias in the group assessing percentage risks.

In general, that A-B-C (“unquantified”) group again showed the highest estimation of flood risk. The group with percentage risk information showed the least overestimation of risk, but still tended to exaggerate this risk on the scales they marked.

Throughout the tests, the researchers had subjects rank their concern for the hypothetical flood-prone residents because flood communication stops not at understanding, but at concern that motivates a response. Grounds et al. conclude:

Although percent chance is often thought to be a confusing form of likelihood expression…the evidence reported here suggests that this format conveys the intended likelihood information, without a significant loss in concern, better than the return period or omitting likelihood information altogether.

How concerned these participants felt watching the flood of hits in the World Series…well, that depended on which team they were rooting for.

While the ranks of women weathercasters are growing slowly, they continue to lag behind their male colleagues in job responsibilities.

A new study to be published in the Bulletin of the American Meteorological Society shows that 29% of weathercasters in the 210 U.S. television markets are female. This percentage has roughly doubled since the 1980s.

Despite this progress, only 8% of chief meteorologists are female. Meanwhile, 44% of the women work weekends while 37% work mornings. Only 14% of the women work the widely viewed evening shifts.

WeathercastersTime

Last year, 11% of evening or primetime weathercasters were female. That’s only about one-third the percentage reported in a study published in 2008, suggesting a possible decline in female representation in this high-profile broadcast slot.

Educational levels were gender dependent, as well. While 52% of the women had meteorology degrees, 59% of the men did.

Alexandra Cranford of WWL-TV in Slidell, Louisiana, the author of the new study, gathered her data in 2016 from TV station websites. The biographical information was compiled for 2,040 weathercasters, making the study the largest of its kind. Because it relied on self-reported, publicly available information, Cranford suggests that there may be some underrepresentation of various factors: online bios tend might tend to omit information that makes broadcasters look less qualified or experienced. The bios on males were somewhat less likely to omit their exact position at the a station, while the bios on females were somewhat less likely to omit education information.

Previous studies have shown that viewers tend to perceive men as more credible and thus more suited for a variety of broadcast roles, from serious news situations to commercial voice-overs. This perception was one of the motivations for Cranford’s study and may be weighing on hiring and assignment practices for weathercasters. In the article, Cranford notes that past research had indicated,

Constructs including the “weather girl” stereotype and gender-based differences in perceived credibility could potentially contribute to the percentage of women in broadcast meteorology remaining low, especially in chief and evening positions.

Based on the new data, Cranford concludes,

Additional research should explore if factors such as persistent sexism in hiring practices or women’s personal choices could explain why fewer female weathercasters have degrees and why women work weekend shifts while remaining underrepresented in chief meteorologist and evening positions.

In carrying out its mission, AMS provides a broad range of support for the science and services making up the atmospheric and related sciences. As a part of this support, AMS has a long history of being a voice on behalf of science and the scientific method—as do most other scientific societies such as AAAS, AGU, Sigma Xi, and many, many others. This past year has been especially challenging for all of us as pressures and outright attacks on science have become far more prevalent. AMS has always been careful to be nonpartisan, to avoid being policy prescriptive, and to really focus on science. We have not, however, shied away from taking strong positions on behalf of the integrity of science.

The hope is that the community and society will view AMS journals, statements, and other material as reliable sources of information on the scientific disciplines AMS covers. AMS statements, in particular, are developed with the goal of being broadly accessible to those seeking credible summaries of current scientific knowledge and understanding on various topics. Beyond being a resource, however, it is vital that AMS proactively stand up for the integrity of science and the scientific process—especially when it is mischaracterized in ways that might impact policy decisions or mislead the public.

There is an extraordinary amount of misinformation being disseminated through many outlets on a variety of topics (but perhaps most notably those associated with climate change)—far more than one can effectively monitor or hope to address. With so many incorrect or misleading statements out there, it can be hard to know when to jump into the discussion. Recognizing that we cannot address all instances of misinformation, AMS has focused instead on taking a more public stance when policy makers in leadership positions make statements that mischaracterize the science. Thus, this past year for example, AMS has sent letters to the EPA administrator and the Secretary of Energy (see the “AMS Position Letters” for an archive of all letters that have been sent by AMS).

Protecting the academic freedom of researchers, and the freedom to present their scientific results broadly and without censorship, intimidation, or political interference, has also been important to AMS for many years. These fundamental precepts upon which scientific advancements depend have come under attack before, and AMS has maintained a strong “Statement on the Freedom of Scientific Expression” for a number of years to make the Society’s position clear.
Scientific advance requires that all data and methodologies leading to research results be openly and freely available to others wishing to replicate or assess that research. That said, AMS has spoken out to protect the confidentiality of discussions among researchers as they develop ideas and critically assess the work of others. These candid discussions are essential and must be able to happen without fear among those involved that comments might be taken out of context to attack the research or the researchers.

AMS membership is diverse and not all members have been supportive of these efforts. I can appreciate the concerns some may feel, and know there is a danger of acting out of bias, despite our putting a lot of time and energy into avoiding biases. I know, as well, how easily inherent biases can color the way one might read these statements or letters. I also know, however, that to remain silent in the face of clear mischaracterization of science or to fail to defend the scientific process is wholly inconsistent with the AMS mission of “advancing the atmospheric and related sciences, technologies, applications, and services for the benefit of society.” I’m proud to be part of an organization that has such a strong history of standing up for the integrity of science.

(Note: This letter also appears in the September 2017 issue of BAMS.)

by Douglas Hilderbrand, Chair, AMS Board on Enterprise Communication

Early August seems forever ago. Hurricanes Maria, Irma, and Harvey were only faint ripples in the atmosphere. The nation was getting increasingly excited for the solar eclipse of 2017; the biggest weather question was where clear skies were expected later in the month.

During this brief period of calm in an otherwise highly impactful weather year, leaders and future leaders from the Weather, Water, and Climate Enterprise gathered together at the AMS Summer Community Meeting in Madison, Wisconsin, to better understand how “The Enterprise” could work in more meaningful, collaborative ways to best serve communities across the country and the world. Consisting of government, industry, and the academic sector, the Enterprise plays a vital role in protecting lives, minimizing impacts from extreme events, and enhancing the American economy.

The AMS Summer Community Meeting is a unique time when the three sectors learn more about each other, about physical and social science advances, and discuss collaboration opportunities.  Strengthening relationships across the Enterprise results in collaborations on joint efforts, coordination in ways that improve communication and consistency in message, and discussion of issues on which those in the room may not always see eye-to-eye. Every summer, one theme always rises to the top — the three sectors that make up the Weather, Water, and Climate Enterprise are stronger when working together vs. “everyone for themselves.”

This “true-ism” becomes most evident during extreme events, such as the trifecta of devastating hurricanes to impact communities from Texas to Florida to Puerto Rico and the U.S. Virgin Islands. The AMS Summer Community Meeting (full program and recorded presentations now available) featured experts on weather satellites, radar-based observations, applications that bring together various datasets, communications, and even the science behind decision making. As Hurricanes Harvey, Irma, and Maria formed, strengthened, and tracked toward land, relevant topics discussed at the Summer Community Meeting were applied under the most urgent of circumstances. GOES-16 images, though currently “preliminary and non-operational,” delivered jaw-dropping imagery and critical information to forecasters. As Harvey’s predicted rainfall totals created a dire flooding threat, the entire Enterprise rallied together to set the expectation that the flooding in eastern Texas and southwestern Louisiana would be “catastrophic and life threatening.”  This consistency and forceful messaging likely saved countless lives — partially due to the Enterprise coming together a month before Harvey to stress the importance of consistency in messaging during extreme events.

If you are unfamiliar with the AMS Summer Community Meeting, and are interested in participating in the summer of 2018, take some time and click on the recorded presentations over the past few years (2017, 2016, 2015).  In 2016, the Enterprise met in Tuscaloosa, Alabama, home of NOAA’s National Water Center, and discussed recent advances in water forecasting and the launch of the National Water Model.  A year earlier, in Raleigh, NC, future advances across the entire end-to-end warning paradigm were discussed.

We don’t know when or what the next big challenge will be for the Weather, Water, and Climate Enterprise, but a few things are certain… The state of our science — both physical and social —  will be tested. Communities will be counting on us to help keep them safe. And to maximize the value chain across the Weather, Water, and Climate Enterprise, we will need government, industry, and academia continuing to work together and rely on each other. These certainties aren’t going away and provide the impetus for you to consider participating in future AMS Summer Community Meetings.
