Virtual Northeastern Storm Conference a Success

The 46th annual Northeastern Storm Conference was held virtually April 23-25, 2021, and was a resounding success!

The Friday evening Ice Breaker Speaker was meteorologist and Lyndon State College alumnus Pete Bouchard (’92). He is currently a broadcast meteorologist for NBC 10 in Boston, Massachusetts.

The virtual conference featured career-focused panel discussions to workshops on topics like science communication.

Saturday night’s Banquet Dinner Speaker was Bryan Norcross. Currently, Bryan is a Hurricane Specialist at WPLG in Miami, FL. This happens to be where he began his television career almost 40 years ago!

Bernadette Woods Placky closed out the conference as the Sunday Keynote Speaker. Bernadette is the Chief Meteorologist and Director for Climate Central’s Climate Matters program.

We look forward to the 47th annual Northeastern Storm Conference in March 2022, to be held in Burlington, Vermont! Check out for later details.

NVU claims their first Max University Challenge title

The goal of the Max University Challenge is to help future meteorologists tell better weather stories by equipping them with the latest Max Ecosystem technologies.

Rob Koenig (left) and Bobby Saba (right) from Northern Vermont University earned the 2021 Max University Challenge title by building scenes that are clever, engaging and easy to understand.

When severe weather is approaching, it’s critical to deliver important information to your audience as clearly as possible to help them make potentially life-saving decisions.

The team from Northern Vermont University achieved this goal with a simple grid that illustrates the projected severity levels of an oncoming storm during a five-hour period. The judges complimented the team on creating a graphic that can tell the full weather story, even if a presenter is not on camera.

The team’s second graphic demonstrates a high skill level with Max tools by first showing a region that is currently under a tornado watch, then zooming in to highlight a specific area for which a tornado warning has been issued. The graphic also includes a simple explainer on the meanings behind tornado watches and tornado warnings.

The Weather Company, an IBM Business, strives to offer meteorology students an opportunity to better understand what they can be and where they can go in their careers. We also hope that unfettered access to Max technology helps develop their skills beyond their expectations.

Agency of Transportation and Northern Vermont University Celebrate 15 Years of Partnership

Students produce weather forecasts for AOT Maintenance Districts

Lyndonville, Vt. – The Vermont Agency of Transportation (AOT) and Northern Vermont University (NVU) are celebrating 15 years of working together to manage Vermont’s winter road conditions with public safety in mind.

Students in NVU’s Atmospheric Sciences program provide daily weather forecasts for AOT maintenance districts from November through April. AOT uses this tailored weather forecast information to help with workforce management and strategies to tackle winter weather.

“All of our districts rely on the students’ weather forecasts to plan their winter highway maintenance activities every time there are conditions that potentially require us to plow or treat the roads,” said Maintenance Bureau Director Todd Law. “The forecasts from the NVU meteorology students are reliable, professional, and a vital source of information for our maintenance planning throughout the winter.”

Each district receives a forecast that is specific to its area of the state, enabling maintenance staff to plan for impending weather.

Atmospheric Sciences students forecast for 9 AOT maintenance districts

“AOT reached out to NVU [Lyndon State College at the time] because of our expertise in weather forecasting. They wanted better information to make better decisions to make roads safe and manage their workforce,” said Jay Shafer, NVU professor of Atmospheric Sciences who created the project with AOT. Jay has managed more than 130 students in these forecaster roles. “The value of this program for the students is learning how to work together as a team. Learning to collaborate and communicate is more of an art than a science, and the only way to learn this is to jump in and do it.”

The NVU-Lyndon student meteorologists apply for the jobs each year during their junior and senior years. The students are paid for their work, which helps to make college more affordable. The students forecast weather conditions every day, including weekends and holidays when inclement weather is anticipated.

Working in teams of three, each student is assigned to three districts to forecast during their shift and will rotate through all nine districts during the season. Students work from one to three days each week, creating their forecasts with information gleaned from a variety of information sources between 11 a.m. and 1 p.m.; all forecasts are due to AOT at 1 p.m.

Rosemary Webb, who will graduate in May with a degree in Atmospheric Science, is one of the lead forecasters, a perfect role for a student looking to land a position as a weather forecaster. “It’s real-life experience actually forecasting for a client who uses it to make decisions,” she said. Webb leads her group of three and is responsible for writing a summary of statewide weather based on the group’s discussion. “In my first year it was a little stressful figuring out how to forecast in a short amount of time, but then you get into a routine.”

Bobby Saba, who is working to complete a bachelor’s degree in Atmospheric Sciences and an associate’s degree in Broadcast and Digital Journalism in May 2022, joined the program this year. “I got involved as soon as I could!” he said. As a weather broadcaster, Saba will have to do his own forecasting. “Being able to do this for a state that has some pretty wild weather will help set me apart from others applying for the same jobs.”

“It’s close to what a real field job feels like, and the students see the application of what they are learning,” Shafer said. “This experiential learning helps to make our atmospheric science program strong and greatly benefits the State of Vermont.”

AOT looks forward to continuing the partnership with NVU next winter.

“The program has been a great success, and we are grateful to the students and their professors for their ongoing work to support Vermont winter highway maintenance and safety,” said AOT Chief Engineer and Highway Division Director Ann Gammell.

Successful 45th Annual Northeast Storm Conference

Students and Faculty at AMS 2020

Last week, 35 Atmospheric Sciences students and faculty attended the American Meteorological Society’s Annual Meeting and Centennial Celebration in Boston, MA.

Dr. Ari Preston presented a poster on lightning cessation characteristics between severe and nonsevere storms using polarimetric radar data. Total lightning data for the storms are obtained from the Washington, D.C., Lightning Mapping Array (DCLMA). Storms are tracked using the Warning Decision Support System–Integrated Information (WDSS-II) software, producing time series of radar- and lightning-derived parameters. Trends in polarimetric radar parameters, such as graupel characteristics, at different temperature levels are compared between severe and nonsevere storms near the end of their lightning activity.

Seniors Sarah-Ellen Calise and John Drugan presented posters on their individual research projects. Sarah-Ellen is looking into improved forecasts of incoming solar radiation using machine learning and ensemble weather model output. Sarah-Ellen used output from a 15-member WRF ensemble combined with deep learning techniques to improve predictions of incoming solar radiation at surface stations in Vermont. Employing deep learning techniques on the ensemble output results in up to 30% improvement in forecast accuracy of incoming solar radiation over that of the equivalent raw ensemble forecasts. John superimposed polarimetric radar data and total lightning data from the Washington, D.C. Lightning Mapping Array (DCLMA) using the Warning Decision Support System-Integrated Information (WDSS-II) software to develop lightning cessation guidance algorithms. The goal of this project is to analyze the presence of graupel at different temperature levels in the mixed phase region of a storm (-20 to 0C) to determine a correspondence to the last detected lightning flash.

We hosted an alumni gathering on Tuesday evening. This was a great time for networking and catching up with many atmospheric sciences alumni!

Dr. Jay Shafer presented a talk on Predicting Wet Snow Icing Risks on the Grid Edge. He highlighted a successful research-to-operations effort to improve the prediction of power outages caused by wet snow icing. Wet snow icing is poorly understood, with no existing electric distribution engineering standards for wet snow loading, and no widely accepted meteorological standards to identify conditions when wet snow icing occurs. This work presented a method to identify wet snow icing potential using surface wet bulb temperature, in addition to an outage prediction method.

Dr. Jay Shafer gives a talk on his research.

Dr. Janel Hanrahan facilitated a Town Hall Meeting with titled “Getting creative with climate change outreach: promoting scientific engagement, improving science literacy, and building community.” Panelists were Atmospheric Sciences students (seated, from left to right): Jonathan Hutchinson, Maison DeJesus, Lillie Farrell, and Patrick Wickstrom. In this Town Hall session, student and faculty members of The Climate Consensus, an outreach group at Northern Vermont University-Lyndon, will share their experiences with community engagement on this important topic. They will discuss creative ways they have prompted discussion about climate change within the local community and important lessons learned.

Fall Break Adventures

This past week (October 7-11) was Northern Vermont University’s Fall Break. Despite not holding classes, Atmospheric Sciences students, faculty, and staff were quite busy!

Faculty Attend UCAR Annual Meeting

Atmospheric Sciences faculty attended the 2019 UCAR Annual Members Meeting in Boulder, Colorado. Dr. Hanrahan and Dr. Preston participated in workshops and breakout sessions to learn about and provide guidance on the directions of UCAR (University Corporation for Atmospheric Research) and NCAR (National Center for Atmospheric Research). They also toured some NCAR facilities including the NCAR-Wyoming Supercomputing Center and the Marshall Field Site.

Students Visit NWS Offices

Five students spent their fall break traveling around the southeast U.S. They visited three National Weather Service offices: Peachtree City/Atlanta, Georgia, Huntsville, Alabama, and Jacksonville, Florida. While at the NWS Jacksonville, they met up with Matt Zibura (wearing the bright blue shirt in the photo below), an LSC alumnus (’87).

Equipment Upgrades

Back at NVU-Lyndon, Dr. Jay Shafer finished installing a wireless Davis Instruments Vantage Pro2 Plus weather station next to our research-grade weather station. This new weather station will assist Northview Weather LLC in creating an intercomparison of solar radiation data between the research-grade Kipp and Zonen solar radiation sensors and the Davis solar radiation sensor. This is useful because our Lyndon Mesonet of weather stations around Vermont mostly uses the same Davis Vantage Pro2 Plus weather stations (which Northview Weather is using to create an incoming solar radiation climatology). We will also now be able to conduct comparisons among the Davis Instruments rain gauge, the research-grade Texas Electronics rain gauge, and the manual CoCoRaHS rain gauge. Jason Kaiser, the Atmospheric Sciences Data Systems Administrator, also completed a much-needed replacement of a projector in one of Atmospheric Sciences classrooms during the fall break.

Atmospheric Sciences Faculty Publish in BAMS

Two Northern Vermont University Atmospheric Sciences faculty had their work published in the July 2019 Bulletin of the American Meteorological Society (BAMS). BAMS is the flagship magazine of the American Meteorological Society (AMS). The peer-reviewed article, Improving Climate Change Literacy and Promoting Outreach in an Undergraduate Atmospheric Sciences Program, outlines the recent implementation of innovative curricular and extracurricular activities related to climate change within the Department of Atmospheric Sciences at Northern Vermont University. The NVU Department of Atmospheric Sciences is at the forefront of improving climate change literacy among the general public through undergraduate education and public outreach.

In the paper, Dr. Hanrahan and Dr. Shafer discuss the importance of improved communication between experts and nonexperts for meaningful climate action to be realized. To achieve this, we expose all Atmospheric Sciences students, regardless of their career pathway, to the science of human-caused climate change. Then, the department encourages students to engage with nonexperts through public events, school visits, and a department-run website, As a result, we have observed a higher level of interest in climate change among students over the past few years. More students have demonstrated a heightened sense of responsibility to engage the public about this challenging topic, and some have expressed an interest in pursuing climate-change-related careers.  

The department thanks Jason Kaiser, Ari Preston, David Siuta, George Loriot, and Dawn Kopacz for productive conversations and helpful feedback. We also thank the faculty and staff at NVU-Lyndon for their enthusiastic support of our efforts. We are appreciative of the work by student recipients of the recently-established Climate Courage Award and Scholarship, Jonathan Hutchinson, Andrew Westgate, and Francis Tarasiewicz, and the donors who made the Climate Courage Award and Scholarship possible, Carl Bayer and Sheila Reed. Finally, we thank all of the former and current Lyndon Atmospheric Sciences students who have demonstrated courage by speaking out about climate change science, especially Arianna Varuolo-Clarke and Kayla St. Germain, who prompted the creation of the Climate Consensus Group in 2014.

Upward Bound & BREE Students Launch Weather Balloons

Upward Bound and BREE students recently visited the Northern Vermont University-Lyndon Department of Atmospheric Sciences and had the opportunity to launch weather balloons! Students in both of these groups are interested in STEM (Science, Technology, Education, and Mathematics) fields.

About Weather Balloons

Every 12 hours, hundreds of people in places around the world launch huge, white balloons into the sky. The balloons float upward, each tethered to a box of instruments that collects data about the temperature, humidity, and winds in the atmosphere. These are weather balloons. The boxes of instruments are called radiosondes. The data that radiosondes collect is used in weather models to improve weather forecasts. The Department of Atmospheric Sciences at NVU-Lyndon launches weather balloons to gather data during hazardous weather situations (for example, severe thunderstorms, freezing rain, etc.). This data is also used in several Atmospheric Sciences courses. We also welcome the opportunity to launch weather balloons for visitors, like the Upward Bound and BREE students.

The Upward Bound program is a national college-preparation program that offers free educational, cultural, and social activities for eligible high school students from low- or modest-income families who will be the first in their family to attend college. The Upward Bound students got a chance to launch a weather balloon. These students are specifically interested in STEM fields and/or attending Northern Vermont University. A couple of students said that Atmospheric Sciences especially interested them.

Atmospheric Sciences student and NVU-Lyndon Admissions Student Office Professional Peter Kvietkauskas led a tour of the NVU-Lyndon campus, including stopping by the News7 studio. Dr. Hanrahan and Dr. Preston then talked with the students about the Climate Change Science and Atmospheric Sciences degrees, as well as describing experiential learning opportunities and storm observation field experience that Atmospheric Sciences students have.

Three undergraduate students, Ann Marie Matheny from Indiana University Bloomington, Connor Zwonik from the University of Vermont, and Giorgio Sarro from the University of Wisconsin-Milwaukee, recently visited NVU-Lyndon and had a chance to see what goes on in the Department of Atmospheric Sciences. This included launching a weather balloon. As the weather balloon rose, they also discussed the weather data from the radiosonde. These students are working with faculty and graduate students on the transdisciplinary BREE (Lake Champlain Basin Resilience to Extreme Events) research program. These three students are summer interns through the Vermont EPSCoR (Established Program to Stimulate Competitive Research) Center for Workforce Development and Diversity, which works to cultivate and prepare students in science, technology, engineering and math (STEM) fields.

Storm Forecasting and Observation

Storm Forecasting and Observation Program Overview

Dr. Preston and four Northern Vermont University-Lyndon Atmospheric Sciences students participated in the SUNY Oswego Storm Forecasting and Observation Program earlier this summer (May 27-June 15). This program is designed for students to apply concepts from the classroom to the forecasting and observation of thunderstorms. The first two weeks were spent in the field, forecasting severe weather and observing storm structure. This involved launching weather balloons to collect data about the environment, as well as using programs like RadarScope and Baron Mobile Threat Net® to examine radar data and track storms. For the last week of the program, students completed a research project related to their storm observations. Some of the research projects this year used GR2Analyst, IDV, SHARPpy, and BUFKIT for analysis.

Observed Weather

During the 2019 Storm Forecasting and Observation Program, students saw three visible tornadoes (and one rain-wrapped), over a dozen wall clouds, dust devils, 0.25-inch hail, mammatus clouds, cloud iridescence, and incredible lightning activity. Students traveled through 10 different states (see trip log below), including Pennsylvania, Ohio, Indiana, Illinois, Missouri, Kansas, Oklahoma, Texas, New Mexico, and Colorado.

“Down” Days

During the “down” days, students got to visit the Big Well Museum in Greensburg, KS, as well as the Twister Museum in Wakita, OK. They also got to tour the National Weather Center in Norman, OK, which houses the Storm Prediction Center (SPC). Bill Bunting, Chief of Forecast Operations at the SPC, talked about the Storm Prediction Center right outside of the SPC’s forecast room.

Daily Logistics

Overall, 13 students participated in the Storm Forecasting and Observation program. This required two separate vans with ham radio communication (like in the movie Twister). On a typical “chase” day, the forecast team would lead a weather briefing around 8:00 am. The vans would then drive 5-6 hours (on average) to the target area. This would get them to their destination by 3:00 pm, which provided enough time to launch a weather balloon before the main period of thunderstorm development at 5:00 pm. Then, the students would observe the severe storm(s) for the next several hours before losing daylight. After sunset, faculty and students would decide where to stay that night to put them in the best position to chase again the next day. With this in mind, it usually meant driving late into the night.

Trip Log Summary

6/7Oklahomadown day; toured the University of Oklahoma campus, and visited the National Weather Center
6/8ColoradoThis was the most exciting day of the Storm Forecasting and Observation trip! The group observed two landspout tornadoes in Kanorado, KS at 20Z. Each lasted 5-10 minutes and occurred one after the other. Two condensation funnels were both visible for a short period as one dissipated and a new one formed. Following this, the group observed three supercells with well-defined hook echoes near Denver. These storms were associated with breathtaking mammatus clouds. At this point, the third tornado of the day briefly formed (occurring for about 10 seconds) in the southern-most supercell. Afterwards, some of the students spotted a brief rain-wrapped tornado in the middle supercell.

Questions & Answers About the Storm Forecasting and Observation Program

What was the most enjoyable part of the trip?

This whole trip was an unbelievable experience, but if I had to pick what I enjoyed the most it would clearly have to be the storms. Before coming out, I had never seen anything compared to what we saw in the plains. Being able to see an entire supercell and admire its structure and watch as it tries to produce a tornado is something special that I don’t think I’ll ever experience again.

Bobby Saba – sophomore, Broadcast Concentration

Why did you choose to storm chase this summer?

I chose to chase this summer because severe weather has been a dream of mine since I was five years old. I remember sitting through a particularly bad thunderstorm and hearing the rain approach my porch.  It was torrential rain with severe lightning and booming thunder. Being able to finally chase this dream has been one of the most gratifying experiences I’ve ever had and I am so grateful that I was able to do this. Between the people I’ve met, the memories I’ve made, and the weather I’ve seen, this has been one of the most exhilarating things I’ve ever been able to do.

Catie McNeil – sophomore, Broadcast Concentration

What have you learned on this trip?

I now know how to analyze data to figure out where severe weather is likely to occur. This is very important to know as an aspiring meteorologist so I will be able to share my knowledge with the public. I have seen a lot of clouds in textbooks and pictures, but seeing mammatus clouds and wall clouds in person are so much different; it is amazing. Although I want to broadcast the weather, I love learning about severe weather. I have only completed one year of college so I am glad that I decided to do this program because there are quite a few people here who really know what they are doing and are doing a great job explaining things to me.

Camryn Kruger – sophomore, Broadcast Concentration

 Why did you choose to storm chase this summer?

It is something that I’ve always wanted to do. I remember one of the small thunderstorms with my dad in Maine just so I could hear thunder. I grew up watching Tornado Hunters and I was absolutely obsessed. Twister is also my favorite movie so storm chasing just felt like something I needed to do.

Maddie Degroot – junior, National Weather Service/Military & Private Industry Concentrations

Student Research

Bobby Saba, Canton, TX Storms
Bobby analyzed two storms that moved through Canton, TX on 29 May 2019.  He was looking to find common radar signatures between storms producing multiple tornadoes.

Camryn Kruger, Cloud Iridescence
Camryn examined the colorful iridescence that occurred around the anvils of supercells in New Mexico on 2 June 2019. Specifically, she looked for signatures of iridescence in radar and satellite fields.

Catie McNeil, High Instability/Low Shear Tornadoes

Catie studied common characteristics that produced tornadoes in high instability (i.e. Convective Available Potential Energy, CAPE), low vertical wind shear environments. Specifically, she compared the environment for the Jarrell, TX tornado (CAPE greater than 8000 J/kg) on 27 May 1997 to the 9 June 2019 tornado near Fort Worth, TX.

Maddie Degroot, Mysterious Mammatus

Maddie examined the stunning mammatus clouds associated with the three supercells near Denver, CO on 8 June 2019. This study showed the difficulty in identifying mammatus clouds using the standard WSR-88D S-Band radar.

Coriolis Effect Demonstration

The American Meteorological Society defines the Coriolis effect as “an apparent force, relative to the earth’s surface, that causes deflection of moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the earth’s rotation.”

Every couple of weeks, students in Dr. Hanrahan’s Atmospheric Dynamics class present important concepts to their peers during Content Reviews. For one Content Review, Jonathan Hutchinson and Alex DaSilva took the group out to the Weather Deck to help the class better understand the Coriolis effect.

In this Coriolis effect demonstration, Alex is at the center of rotation and Jonathan is throwing a ball toward him. When they rotate counterclockwise (cyclonically) as viewed from above, like in the Northern Hemisphere, the ball appears to be deflected to the right. When they rotate clockwise (anticyclonically) as viewed from above, like in the Southern Hemisphere, the ball appears to be deflected to the left.

This is an important concept for atmospheric sciences students in order for them to understand and predict atmospheric motion. For example, the Coriolis effect is what causes storm systems like hurricanes and nor’easters to spin counterclockwise in the Northern Hemisphere.
