Tropical CyclonesSecondaryeyewall

Accurate forecasts of hurricanes depend on an in-depth understanding of their underlying physical processes. I am interested in examining the processes that determine hurricane formation, structure, and intensity. My research focuses on the development of tropical disturbances, internal features of mature storms (e.g. spiral rainbands, concentric eyewalls), and interactions with the surrounding environment.

Radar Meteorology

Airborne radars can collect observations of storms in remote locations
such as over the open ocean waters. These radars can utilize scanning techniques that are designed for Global_hawkretrieving the full 3D wind structure of any precipitating region within range. The bulk of my research uses airborne Doppler radar for examining the structure of storms. I am also interested in improving wind retrieval techniques for various airborne radars.

In addition to airborne radars, my research interests include using spaceborne radars for examining storm precipitation structure. These observations come from the recently launched NASA Global Precipitation Measurement (GPM) Core satellite’s Dual-frequency Precipitation Radar (DPR). Like its predecessor TRMM-PR, this radar will provide continuous observations across the globe that will be important for understanding storm structures and precipitation climatology.

Mesoscale Processes

My interests are in connecting kinematic and microphysical observations to determine the precipitation processes of various mesoscale storms. I am involved in NASA projects that use a combination of land-based, airborne, and spaceborne (GPM DPR) radars to learn more about precipitating systems ranging from squall line convection to storms modified by complex terrain.
