Associate Professor, Department of Atmospheric Science Ph.D.,
Atmospheric Sciences, My work addresses the mesoscale dynamics of precipitating systems, boundary-layer circulations over flat and complex terrain, cloud dynamics, and cloud and precipitation radars. The main tools have been the Wyoming Cloud Radar and the UW King Air aircraft. |

fine-lines in the pre-convective continental boundary layer (since 2002): IHOP (International Water Vapor Experiment, May-June
2002) brought together the latest technologies to document the detailed
4-D water vapor structure and its impact on convective initiation. Our work
focused on the interpretation of a vertical velocity bias found in radar data
of the optically-clear convective boundary-layer, the dynamics of coherent
eddies in the convective boundary-layer, the fine-scale structure of cold
fronts and drylines, and convective initiation mechanisms. In a future campaign,
we hope to study
the formation & fine-scale dynamics of drylines in

towering cumuli over the Santa Catalina Mountains in Arizona, and of the
interaction of cumulus convection with the topographically-controlled mesoscale
circulation. soundings, surface stations,
digital photogrammetry, profiling remote sensors, numerical modeling.
Boundary-layer circulations over relatively warm water
(since 2004): In early 2004 we examined cloud streets over Lake
Michigan during cold-air outbreaks associated with downstream lake-effect
snow. We characterized the vertical velocity and buoyancy characteristics of the
convective cells that make up cloud streets. We hope to examine BL circulations over
warm water and downstream land areas further as part of OWLES (Eastern Great
Lakes Lake Effect Snow Project).
