Aaron (Ari) Preston, Ph.D.

Assistant Professor, Atmospheric Sciences

Dr. Preston joined the Atmospheric Sciences faculty in 2017 after earning his Ph.D. in Meteorology from Florida State University (FSU). During his time at FSU, Dr. Preston taught seven meteorology classes and participated in the nationally recognized Preparing Future Faculty program. He looks forward to engaging students in the Lyndon community and getting them excited about the weather by implementing classroom activities that make them apply concepts from the classroom to the real world.

He is currently interested in two aspects of deep convection—convective transport and atmospheric electricity. His dissertation research examined the atmospheric and chemical transport associated with tropical cyclones (TCs) using numerical modeling. The contribution of TCs to upper atmospheric chemistry is valuable to both the atmospheric chemistry and climate modeling communities, especially in the context of increasing emissions and a changing climate. He also has considerable experience conducting lightning-related research. For his M.S. thesis, he developed lightning cessation guidance using polarimetric radar data that improved lightning warnings for America’s space program at NASA Kennedy Space Center and Cape Canaveral Air Force Station.
