Millersville Meteorology Celebrates 30 Years of Research
Millersville alumni, faculty, and students attend 106th ams conference
This year marked the 40th straight year that students in the Millersville Meteorology program had an opportunity to attend the Annual Meeting of the American Meteorological Society (AMS). The 106th Annual Meeting of the AMS took place in Houston, TX, from January 24-29, 2026. In addition to attending all other conference sessions and special symposia during the week, students had the opportunity to take part in the AMS Student Conference. Niko Omiridis, Melanie Jones, and Rebecca Butterfield presented their research as part of the student research poster session.

Additionally, Millersville University meteorology and emergency management programs hosted the MU Alumni and Friends reception on January 27th where over 200 students, alumni, and friends of the programs attended the celebration. Dr. Richard Clark (Professor of Meteorology, Emeritus and Past President of the AMS) and Dr. Sepi Yalda (Professor of Meteorology, CDRE Director) served as co-organizers for the event. The event was sponsored by generous donations from Integrated Systems Solutions, WeatherTrends, AccuWeather, Millersville University's Alumni Association, and the MU College of Science and Technology.
space weather activities
Millersville Meteorology remains quite active in the Space Weather (SW) Community. We are the only program in the U.S. to offer a Graduate Certificate in Space Weather and Environment: Science, Policy, and Communication that attracts professionals from a wide range of careers. Our graduates work in fields from solar physics research to space weather forecasting and occupy leadership positions across public, private, and academic sectors. A group of MU SW current students, graduates, instructors, and program coordinators (current and emeritus) attended the 2026 Space Weather Workshop in Boulder, CO (April 27-May 1, 2026).
Drs. Sepi Yalda and Rich Clark developed and co-chaired a panel presentation and discussion along with Dr. Mike Wiltberger (National Center for Atmospheric Research (NCAR)) on Building the Space Weather Workforce of the Future on May 1. The session featured Dr. Dan Welling (University of Michigan), Dr. Robert Steenburgh (NOAA, Space Weather Prediction Center), Dr. Barbara Thompson (NASA GSFC), Marissa Vara (NCAR), and Dr. Tamitha Skov (Space Weather Woman and Faculty Associate in Space Weather at Millersville University). The session also featured poster lightning talks where current student in the MU SWEN Certificate Program, Tanya Melnik, presented a talk titled "Bridging Space Weather Operations and Local News."
In addition, MU SWEN current students, Tanya Melnik, MaryBeth Kiczenski, and Vincent Ledvina along with other co-authors presented a poster titled "Initial Survey Results on Aurora Chasers' Use of Space Weather Forecasts and Uncertainty Information." Another poster titled "Bridging Space Weather Operations and Local News" was presented by Tanya Melnik and Vincent Ledvina. Two MU graduates, Mike Cook and Tony Williams were co-authors on these posters. A third poster was presented by current MU SWEN students, MaryBeth Kicsenski and Tanya Melnik, along with their co-author titled "From the Sun to Social Media: How Aurora Chasers Use Space Weather Data."

project tiltting created by Millersville METEORology students
Remember the group of Millersville meteorology students who chased the EF-3 tornado in Mullica Hill, NJ, during Hurricane Ida? Under the leadership of Weather Information Center Director Kyle Elliott, they created the Thermodynamic Investigation of LCL Thresholds at Tornadogenesis and its Influence in the Northeast and Great Plains (TILTTING) project. For details on the project and how to support the students, visit TILTTING (millersville.edu/tiltting). Nearly 20 students are involved in the project, and 7 of them deployed to the Great Plains for a two-week period during May 2024 to conduct tornado research. Under the guidance of Dr. Greg Blumberg, this "chase team" released balloons to obtain atmospheric profiles of temperature, pressure, humidity, and wind velocity near supercells to assess the storm environment. While in the Plains, the students visited the Storm Prediction Center (SPC) in Norman, OK, and talked with forecasters on the operations floor. They met with two of the senior leads at the SPC - John Hart and Rich Thompson - and toured the vehicle bays at the National Weather Center to see the mobile radars and mesonets. On chase days, the team shared the data collected with SPC and local National Weather Service (NWS) offices. Overall, four Intensive Observation Periods (IOPs) were conducted during the two-week period, and the team is aiming to present their findings at upcoming conferences.

The students have also designed their own probes that will eventually be used to penetrate and measure wind velocity and pressure perturbations within the condensation funnel of a tornado. IOPs have and will continue to be conducted in the Northeast, with teams of 6-10 students deploying on a rotating basis. Three IOPs took place in the Northeast during Summer 2022, with another three happening during Summer 2023. Incorporation of this data into numerical weather prediction models will increase accuracy of severe weather forecasts, improve tornado warning lead times and, most importantly, save lives.

VALIDATION OF SODAR/RASS MEASUREMENTS WITH RAWINDSONDE RETRIEVALS
From 2018-2023, Millersville faculty and students conducted a series of rawinsonde launches over the course of 2-3 days for the purpose of validating the wind and virtual temperatures measurements obtained by the Allegheny County Health Department (ACHD) using a Scintec Acoustic SODAR system with a RASS extension. Typically, three meteorology students from Millersville University assisted the ACHD with a research initiative involving Sound Detection and Ranging (SODAR) observations and Radio Acoustic Sounding System (RASS) retrievals with rawinsonde measurements in Clairton, Pennsylvania. Under the direction of faculty members Drs. Greg Blumberg and Richard Clark, as well as Weather Center Director Kyle Elliott, the students launched weather balloons to validate the on-site SODAR measurement - a requirement of the EPA. A radiosonde, or instrument used to transmit pressure, temperature, and relative humidity measurements at various levels of the atmosphere, was attached to each balloon. When a radiosonde is tracked so that wind speed and direction measurements are also provided, it is called a rawinsonde observation. The data was used to better understand the changes in the diurnal transition of the planetary boundary layer in the Monongahela Valley and its impact on the transport of pollutants.
