Lubchenco: Let's "Embed" Science in Society

In a “post-truth” world of contemporary politics and culture, “it’s easy to assume that science is really in trouble and everything is bad,” said Jane Lubchenco in her James R. Mahoney Memorial Lecture in Washington, D.C., last month.
In fact, science does have its image problems: most people don’t interact with science and don’t know scientists. A recent study showed that only 30% of Americans can even name one living scientist—and the most commonly cited name on that list last year, Stephen Hawking, no longer qualifies.
But the annual Mahoney lecture, hosted in part by AMS and NOAA, is now online, and you can see for yourself that even with a hard-hitting topic of “Science in a Post-Truth World,” Lubchenco was full of hope and practical advice about engagement, and ultimately about working toward a new paradigm of “embedding” scientists in society.

First of all, the vital signs of science are good. Public trust in scientific leaders has been stable for decades, even as it has plummeted for bankers and politicians. A majority believe science has been beneficial for society.
Lubchenco, a marine ecologist and now Distinguished University Professor at Oregon State University, has solid reason to think we can build on such durable trust. She has a history of commitment to communicating about science, as a former president of the American Association for the Advancement of Science and later as the NOAA Administrator. She’s been involved in efforts to help scientists communicate better—for example as a co-founder of COMPASS, a group that among other things provides a handy online workbook for scientists engaging the public.
In part Lubchenco argues for better understanding of the rift between scientists and the public. She cites inequities and “powerful vested interests promulgating a self-serving, anti-science agenda.” She also notes the decline of media business models that has led to citizens individually choosing their sources of information. Meanwhile, people also tune out scientists who seem to have ulterior motives, or are all “doom and gloom.”
Lubchenco says part of the solution is simply putting a real human face on science. The fact that people don’t know scientists means we have “an incredible opportunity. We need more scientists who are seen as scientists by the general public.”
Lubchenco argued that this doen’t mean every scientist is suited to being a celebrity or even a regular public messenger. Research shows that people are considered trustworthy when they are competent—but they also need to be “warm.” Teachers and nurses rated highly in both; professors and scientists rated highly in competence, but were seen as “cold.”
“Part of that is the way scientists are trained to talk to people,” said Lubchenco. It’s the downside of a facts-only, no-stories scientific culture. Lubchenco urges good analogies and metaphors and above all, making a connection with audiences.  “Finding common ground and creating a shared value experience enables you to then pursue things that might be particularly contentious.”
While Lubchenco offered many tips on better communication—understanding audience, keeping messages simple, offering hope, showing value and successes—she went deeper, arguing that scientists need to be “physically and psychologically integrated” with society. She urged scientists to show who they are by working with society. One avenue is to enlist citizen scientists as well as a broader public in observing and other projects.
Lubchenco also wanted her audience to see beyond the dichotomy of applied and basic science—that we need more of the middle way of “use-inspired science” that has immediate relevance as well as prospects for advancing basic knowledge.
What are impediments? Science itself needs to reward its people who are good at outreach, Lubchenco said. They need training and recognition for it. They need to get involved, including running for political office. “I don’t think all scientists should be engaging… but they should all support their colleagues that do.”
There may already be progress in this direction, Lubchenco noted, moving first from an “ivory tower” model of science to a post-World War II “social contract” with the public, producing great benefits. “Now, I think we’re seeing another innovation from social contract to science embedded in and serving society—maybe.”
If people generally don’t know any living scientists, there’s one whose recent example can be an inspiration for Lubchenco’s vision of science more fully “embedded” in society: That would be the late Jim Mahoney, the NOAA Deputy Administrator, AMS president, and public health scientist whose memory this annual lecture honors. Said Lubchenco,

Science is indeed facing some major challenges. Maybe it’s not quite as bad as we thought, but we have unparalleled opportunities to serve society better and this is only going to happen if scientists take the bull by the horns and step up and make things happen.
I’d like to think we can do this in a way that is inspired by Jim’s example in confronting challenging times and figuring out how to navigate those. I would suggest that maybe if he were here, he would say, “It’s time for us to take back the narrative.” It’s time to write a new chapter in the relationship between science and society and for us collectively to have a quantum leap in relevance.”

Your AMS Community Online

by Jordan Stillman, AMS Community Coordinator
After a successful soft launch to AMS board and committee members this past winter, the AMS will be opening up our new online platform, AMS Community, to all AMS members as a new member benefit this May.
The goal of the AMS Community is to enhance communication and improve member engagement. We want to give our members a place to network, communicate, and collaborate, where members can reach out to their colleagues and peers to discuss what’s really important to them, from actual challenges they’re facing in their work to greater issues affecting the weather, water, and climate community. We envision a space where members can troubleshoot problems, solicit advice, seek feedback, and share with one another, creating a vast and thriving pool of communal knowledge.
Those involved in the Community will be the first to know about new AMS resources, like webinars, podcasts, briefings, conferences, and centennial activities. Simultaneously, the Community will also provide improved methods and transparency for connecting with AMS staff and allow volunteers and staff to make members aware of the various opportunities for greater engagement (for example, in policy issues, in local or regional educational opportunities, in statements, in committees, and so on). Already, this new tool is allowing for improved communication among boards and committees and will leave room for even more possibilities with the full member launch.
An intuitive platform, AMS Community includes an easy-to-use discussion board, resource library, and a comprehensive member directory as well as the administrator ability to post announcements and events for the use of all membership. Community members can be tagged with the @mentions functionality (just like Twitter!), participate in discussions, and upload and download useful documents, files, and other handy resources. All active AMS members will automatically be subscribed to the AMS Community and begin receiving notifications once we launch, allowing them to immediately engage with their colleagues at any time, from any location. No need to wait until the next conference!
Keith Seitter described the AMS Community in his January 2018 letter in BAMS, and he sums it up perfectly: “As powerful as this new technology can be, it is really just a tool to connect people. And that is what AMS has always been about—fostering connections among members to serve the broader community and support our science and services. We are all very excited to take those connections—and with them our members’ success—to new levels.”

Mentoring365 and You!

by Tanja Fransen, AMS Councilor and Mentoring Program Ad-Hoc Committee Chair
AMS has a wealth of talent and we’d love to see more of our members signed up for the Mentoring 365 program as mentees, mentors–maybe both!  We should never stop learning. When I started in college and early in my career, I hadn’t even heard of the term mentor, let alone thought of myself as a mentee.  Looking back now, there are so many people who I can count as someone who had a positive influence in my decisions and the path my career took. Coaches, mentors, professors, classmates, co-workers, bosses, supervisors, leaders: they all had a hand in shaping my career because they invested their time in me.  Who are you investing your time in?  Who is investing their time in you?

About ten years ago, through various leadership programs, I learned more about formal mentoring, and I couldn’t help but wonder, “Why doesn’t everyone have a mentor?”  It’s a logical step for anyone who is excited about their careers and looking for guidance. Everyone can benefit from having a non-coworker or non-supervisor to talk with, who will be honest with them, encourage them, celebrate their successes, and help them get to the next levels in their careers.  I’ve participated in several formalized programs, and it always puts a smile on my face to see these mentees doing well.  One of the most amazing moments for me was having a mentee whose son was murdered while we were working together.  We went from my mentoring someone in sciences and government, to learning one of the most amazing lessons about grace and forgiveness, and I’ll never forget that experience.  Not all benefits are apparent when you start a program!
When I was nominated to run for the council of the AMS, it was an obvious niche that was needed. I made it one of my priorities to bring a formal program to all of our AMS members.  With the help of others within AMS who also had our people as their passion, including Matt Parker, Keith Seitter, Wendy Marie Thomas, Wendy Abshire, Maureen McCann, and Donna Charlevoix, we were able to connect AMS with the American Geophysical Union’s (AGU) Mentoring365 program through a signed MOU.  AMS members can join this program as either a mentee, a mentor or both.  You also have access to mentors across the geophysical sciences, including members of the AGU, the Society of Exploration Geophysicists (SEG), Association for Women Geoscientists (AWG), and the Incorporated Research Institutions for Seismology (IRIS).
I’ve met the most amazing people thanks to AMS, from the enthusiastic students, to the eager early career professionals to the mid- and late-career professionals who have the most amazing resumes and curricula vitae!  Let’s tap into all of that energy out there and build Mentoring 365 for the benefit of all!  Join today!

A Letter from AMS President Roger Wakimoto

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

Building AMS Community, Maximizing Value of Our Information

Untitled
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.

Washington Forum to Explore Working with the New Administration

by Keith Seitter, AMS Executive Director
The AMS Washington Forum, held each spring, is organized by the Board on Enterprise Economic Development within the Commission on the Weather, Water, and Climate Enterprise. It brings together leaders from the public, private, and academic sectors for productive dialogue on issues of relevance to the weather, water, and climate enterprise in this country. Compared to our scientific conferences, it is a small meeting with typically a little more than 100 participants. This allows for a meeting dominated by rich discussion rather than presentations. The Forum takes advantage of being held in Washington, D.C., with panel discussions featuring congressional and executive branch staff, as well as agency leadership. It is no secret that this is one of my favorite meetings of the year, and for many in the atmospheric and related sciences community, the Washington Forum has become a “can’t miss” event on their calendar.
The 2017 Washington Forum will be held May 2–4, 2017 at the AAAS Building, 1200 New York Avenue, Washington, DC. (Note that this year’s Forum occurs later in the year than usual.) The organizing committee has put together an outstanding program again this year under the timely, and perhaps provocative, theme: “Evolving Our Enterprise: Working Together with the New Administration in a New Collaborative Era.” The transition to a new administration is bringing changes in department and agency leadership that directly impact our community. The Forum will provide a terrific opportunity to explore how the community can collaboratively navigate these changes in ways to ensure continued advancement of the science and services for the benefit of the nation. I am expecting three days of very lively discussion.
We have a special treat this year in conjunction with the Forum. On the afternoon before the Forum formally begins, Monday, May 1, the Forum location at the AAAS Building will host the second Annual Dr. James R. Mahoney Memorial Lecture. The lecture honors the legacy of Mahoney (1938–2015), AMS past-president and a leader in the environmental field in both the public and private sectors, having worked with more than 50 nations and served as NOAA Deputy Administrator in addition to other key government posts. The Mahoney Lecture is cosponsored by AMS and NOAA, and the annual lecture is presented by a person of stature in the field who can address a key environmental science and/or policy issue of the day. We are very pleased to announce that Richard H. Moss, senior scientist at Pacific Northwest National Laboratory’s Joint Global Change Research Institute and adjunct professor in the Department of Geographical Sciences at the University of Maryland, College Park, will deliver the second Mahoney Lecture. The lecture will begin at 4:00 p.m. and will be followed by a reception. The lecture is free and does not require registration to attend.
If you have ever thought about attending the Washington Forum but have not yet done so, this would be a great year to give it a try. We do limit attendance because of space constraints and the desire for this meeting to have a lot of audience participation and discussion, so I would encourage you to register early. You can learn more about the Forum, and register to attend, at the Forum website.

AMS Journals—Better than Ever

by Keith Seitter, AMS Executive Director, and Michael Friedman, AMS Journals Production Manager
It is interesting how quickly bad news travels, isn’t it? Conversely, good news seems to barely propagate at all if left to its own devices. Changing long-held impressions is even harder, and in some cases, even overwhelming evidence can barely make a dent. As an example, let’s turn to the terrific news coming out of the AMS Publications Commission meeting last May that seems to be taking a long time to filter effectively into the community.
The news at the meeting was universally positive and record setting on nearly every front—from the 3,436 manuscript submissions received in 2015, to the 65-day average time to first decision for those submissions, to the time to publication of accepted manuscripts, which has gone from an all-time low of 95 days in 2015 to the 2016 average (so far) of just 74 days. This is a huge improvement (~72%) from the dark days of 2008, when that metric was well over 200 days.
The dramatic recent drop in time to publication is due in large part to the 2016 transition to a continuous publication model in which each individual article is published online when it reaches final form, instead of waiting until there is a whole issue’s worth of material. The AMS Publications staff tries to take advantage of every potential efficiency improvement it can to drive the time to publication even lower.
These records are just the latest data points mapping a trajectory of continued growth and improvement on all fronts over the past several years, thanks to the efforts of many dedicated volunteers and professional staff, along with effective implementation of technological advances. Meanwhile, AMS publications have maintained the very high quality that has always been their hallmark.  AMS journals continue to rank among the best in the world in our subject areas, and their impact also increased as measured by several objective metrics.
We are doing our best to let the author community know about the excellent performance of the AMS journals on all fronts so that they will not avoid publishing their work with AMS due to concerns based on incorrect impressions. As noted above, however, this can be a frustratingly slow process, and overriding long-held impressions is not easy (we still hear from authors who complain about color charges even though those were eliminated three years ago).
Help us spread the good news. If it has been awhile since you have published in AMS journals, you will be pleased with the improved work flow and speed to publication that we currently provide. If you are considering doing so for the first time, know that along with the prestige and quality that have always been associated with AMS publications, we are able to offer a path to publication much faster than ever before.
(A version of this post appeared in AMS Executive Director Keith Seitter’s 45 Beacon column in the August 2016 BAMS)
 

Distinguished Guests

by Gwendolyn Whittaker, AMS Publications Coordinator & Peer Review Support Manager
In October 2015 an AMS delegation that included a number of AMS Publications staff and AMS Publications Commissioner Bob Rauber took part in a symposium in Tianjin, China, on  “The Latest Developments in Atmospheric Science and Meteorological Journals,” hosted by staff from the journals publishing program of the Chinese Meteorological Society (CMS).
The symposium was an opportunity for AMS and CMS staff to share information on their respective  programs, and to share ideas on the common challenges we face: attracting good manuscripts, supporting volunteer editors and reviewers, maintaining rigorous standards for peer review while making that process as efficient as possible, improving the production time to allow accepted papers to appear quickly, and keeping expenses as low as possible to allow a sustainable business model. There was agreement that such exchanges were extremely useful and should continue.
Despite their myriad other duties (the symposium took place during the CMS Annual Meeting), our hosts took marvelous care of the AMS delegation, including making sure we got to The Great Wall, had endless amounts of good food, and had a tour of the CMS campus in Beijing.
The AMS delegation left China looking forward to a chance to return the favor, and during the week of May 23 we had the pleasure of hosting two guests from CMS who attended the annual meeting of the AMS Publications Commission in Boston: Dr. Lan Yi, executive chief editor of CMS’s Journal of Meteorological Research, and Ms. Aidi Liu, executive chief editor of the Chinese Journal of Atmospheric Sciences (published by the Institute of Atmospheric Physics, Chinese Academy of Sciences).

Groupat45Bcaptioned

While the week’s activities did not quite reach the fever pitch of either society’s Annual Meeting, it was full enough. In addition to sitting in on the Publications Commission presentations and deliberations, Dr. Yi and Ms. Liu had in-depth meetings with AMS journals and BAMS staff on topics ranging from business models to technologies management to the strategies the various teams within AMS Publications use to manage productivity, priorities, and resources. AMS Librarian Jinny Nathans gave an overview of AMS’s involvement in ASLI (Atmospheric Science Librarians International) and gave a tour of AMS headquarters at historic 45 Beacon Street. She also described the project to digitize the entire run of BAMS (back to 1920) in commemoration of the AMS’s Centennial in 2020. While the formal meetings ended with lunch on Friday, the conversations continued during a boat tour of Boston Harbor.

New Survey Shows AMS Members' Positions on Climate Change

The vast majority of members of the American Meteorological Society agree that recent climate change stems at least in part from human causes, and the agreement has been growing significantly in the last five years.
According to a new survey of AMS members, 67% say climate change over the last 50 years is mostly to entirely caused by human activity, and more than 4 in 5 respondents attributed at least some of the climate change to human activity.
Only 5% said that climate change was “largely or entirely” due to natural events (while 6% said they “didn’t know.”)
The findings are from the initial results of a 2016 national survey of more than 4,000 AMS members just released today by George Mason University. The joint GMU/AMS study was conducted in January with support from the National Science Foundation.
Four in five respondents say their opinion on the issue has not changed over the last five years, but of the 17% who did shift, 87% said they feel “more convinced” now that human-caused climate change is happening. Two-thirds of them based this change on new scientific information in the peer-reviewed scientific literature, although in general respondents report basing these changes on multiple sources of information, such as peers and personal observation. Indeed, 74% think that their local climate has changed in the past 50 years.
AMS membership is largely constituted of professionals in the weather, water, and climate fields. One-third of the respondents hold a Ph.D. in meteorology or the atmospheric sciences, and overall just more than half have doctorates in some field.
Yet, while highly educated, the AMS membership represents a different selection of the profession than the climate-expert community commonly cited in statistics about the scientific consensus on climate change. Only 37% of AMS respondents self-identified themselves as climate change experts.
As a result, despite the growing agreement among the membership, there are differences in the results of the new survey compared to the position of climate scientists reflected in the reports of the IPCC.
On one key basic point the difference between the climate expert community and the AMS community as a whole is nearly negligible: AMS members are nearly unanimous (96%) in thinking that climate change is occurring and almost 9 in 10 of them are either “extremely” or “very” sure of this change. Only 1% say climate change is not happening.
However, the AMS Statement on Climate Change, which basically reflects the IPCC findings, not only says “warming of the climate system now is unequivocal” but also says, “It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases.” The new survey shows the AMS community as a whole is still moving toward this state of the science position. Furthermore, the new GMU/AMS survey does not probe members’ views on specific mechanisms of human-caused climate change.
Full results of the survey, including what members think of the future prospects for climate change, are posted here.

The New Capital of Lightning

Imagine being awoken late one night by the near constant glow of lightning overhead—often flickering silently but occasionally rumbling deeply with a strike nearby. Then it happens the same time the next night—and the next, and the next, sometimes lasting for many hours at a time.
Now imagine the nocturnal fireworks happening nearly 300 days per year.
Welcome to Lake Maracaibo, Venezuela.
Based on a scientific paper just released by the Bulletin of the American Meteorological Society (BAMS), the Lake Maracaibo region is the newly crowned lightning capital of the world, taking the throne from a celebrated thunderstorm-prone region of Africa.
Lake Maracaibo, the largest lake in South America, is already well known for its lightning. Boats take tourists onto the water to watch the storms, and the flag of the region—the State of Zulia—features a lightning bolt in honor of the lake’s prolific displays.200px-Flag_of_Zulia_State.svg
Nonetheless, Africa’s Congo Basin had previously been identified by scientists as the world’s lightning hotspot. It stayed that way for several years until the new BAMS article (available online) recalculated rankings based on a new, high-resolution dataset of satellite observations of the lightning flash-rate density.
Lake Maracaibo’s pattern of convergent wind flow–mountain–valley, lake, and sea breezes–occurs over warm lake waters nearly year-round and contributes to nocturnal thunderstorm development 297 days per year on average, with a peak in September. These thunderstorms are very localized and their persistent development anchored in one location accounts for the high flash-rate density. While practically the whole lake is averaging 50 flashes per year, only a small portion qualifies as the world leading hotspot, with more than 232 flashes per square kilometer per year (including cloud-to-ground and cloud-to-cloud lightning).
The BAMS article, “Where are the Lightning Hotspots on Earth?” by Rachel I. Albrecht, Steven J. Goodman, Dennis E. Buechler, Richard J. Blakeslee, and Hugh J. Christian, is derived from 16 years of observations by the Lightning Imaging Sensor aboard the now defunct NASA Tropical Rainfall Measurement Mission satellite.
The team—representing the University of Maryland, Universidade de São Paulo (Brazil), NOAA, NASA, and the University of Alabama in Huntsville—cites several factors for the new lightning champion, including its unique geography and climatology. Storms mostly form during the nighttime hours, after the tropical heating of the day allows warm Caribbean air to mix with colder Andes Mountain air. According to the article, “Nocturnal thunderstorms over Lake Maracaibo are so frequent that their lightning activity was used as a lighthouse by Caribbean navigators in colonial times.”

lightning hot spots

The authors noted that previous studies, using the same satellite capabilities, missed the localized peak at Lake Maracaibo for several reasons. Coarser resolution was one problem (the new study partitions the lake into 20 times more sectors than earlier studies), but so were filtering of high-density outbursts of lightning and calculations made to compensate for limited samples of sparse lightning areas. Where the previous studies were aimed at getting the first useful global overviews, the new study is calibrated to identify hotspots.
Located near the border of the Congo and Rwanda, the now second-ranked Kahuzi-Biéga National Park in Kabare has its own mountainous geography that allows five different locations in the region to rank in the top 10 for lightning flash-rate density. Previous research had shown that the Congo basin boasted the largest flash rate per thunderstorm, and the region still has the world’s largest average flash rate density for any particular part of the day. It averages 5.5 flashes per hour at about 5:30 p.m. local time within a 1° latitude x 1° longitude box. That rate is nearly matched by Lake Maracaibo averaging more than 5.4 flashes per hour at about 3 a.m., when nighttime winds descending the mountain valleys converge over the ever-warm lake waters.
Both of the top two hotspots have lengthy lightning “seasons” but neither had a peak spell matching the 90 flashes per day in early August in the 1° x 1° region of Majagual, Colombia.
Before satellite observations were available, scientists estimated that the whole Earth at any one time experienced about 100 flashes per second. Satellite evidence has reduced that estimate to about 44 to 46 flashes per second, which means Earth experiences nearly 1.4 billion lightning flashes per year. The rate is 20% higher during Northern Hemisphere summer. This variation is in part due to the larger amount of land north of the equator, which lends itself to the surface heating that fuels thunderstorms.
The new BAMS study confirms previous findings showing that lightning activity tends to happen at night in areas closer to mountain ranges and/or coasts but continental-wide lightning activity peaks during the afternoons. And yet the new king of lightning is over water and peaks at night.
The new list of the world’s top 10 lightning flash-rate density hotspots (shown below) includes no sites from North America. Four locations, in Guatemala, Cuba, and Haiti, had more than 100 flashes per square km per year (led by 117 in Patulul, Guatemala). The most lightning prone U.S. location, ranked 122nd globally, was in the Everglades not far from Ft. Myers, Florida, with 79 flashes per square km per year.
