A challenge for meteorologists is to accurately forecast mesoscale precipitation patterns for periods of 12 to 24 hours. Banded, heavy snowfall regions in coastal storms and summmertime deep convective precipitation over the Great Plains are prime examples. Our skill in forecasting these systems leaves much to be desired. My research aims at providing forecasters with practical tools that enable them to anticipate these events.

Research Interests:
Meso- and synoptic-scale dynamics, climate dynamics.
Teaching Interests:
Atmospheric dynamics and the use of computer technology to enhance conceptual understanding.Dr. Clark investigates how mesoscale atmospheric waves are excited and subsequently develop, with particular emphasis on their roles in cyclone evolution, squall line evolution, and boundary layer turbulence.
