The Geography Colloquium Series presents Dr. Jill Coleman on “Hydroclimatic Variability in the Eastern U.S. Associated with Atmospheric Teleconnection Patterns” on Friday, Sept. 21, at 3:05 p.m. in Clippinger 119.
Dr. Jill Coleman
Coleman is Professor of Geography at Ball State University, specializing in atmospheric science and applied geography. Her current research interests include the areas of synoptic climatology and hydroclimatic variability, particularly the relationship between atmospheric teleconnections (e.g., the Southern Oscillation) and Midwest flood and drought patterns. She also investigates topics in the areas of human biometeorology, tropical cyclone climatology and atmospheric hazards.
Abstract: Teleconnections describe how atmospheric or oceanic circulation changes occurring at one location are linked to changes at other locations that are widely separated geographically. On the order of weeks to years, these global associations are recognized by an atmospheric circulation disturbance occurring at select locations or “centers of action,” thereby producing oscillations affecting weather patterns downstream. The strength, phase, and location of the teleconnection pattern establish the geographical extent and severity of the climate impacts. This presentation will focus on teleconnection patterns that influence precipitation, streamflow and atmospheric circulation variability in the Midwest and Eastern United States.
