I am Lei Wang, an Assistant Professor of Atmospheric Science in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. 

My research group focuses on the large-scale jetstream dynamics, and more specifically on the phenomenon of atmospheric blocking and high-impact extreme weather events. Sub-seasonal to seasonal variability poses a forecast gap between medium-range and seasonal timescales. High-impact extreme events such as heatwaves, cold spells, and heavy precipitation episodes often occur on this key timescale, and are challenging to predict.

Group Research Goal: 

What are the effects of changing climate on weather events? And vice versa.
