Research Interests
Primary research interest: intraseasonal and subseasonal climate variability, particularly tropical-extratropical interactions and teleconnected modulation, of: tornadoes and severe convection, precipitation and local circulation, upper-ocean currents and thermal variability, sea ice, terrestrial snow, air quality (ozone, PM10, CO, etc). Also interested in tropical cyclones and tropical convection on multiple time scales. Influence of mountain topography (particularly the Sierra Madre of Mexico and Andes of Chile) on precipitation and air flow, examined through surface in-situ and a broad range of remote-sensing platforms (including TRMM, AIRS, MSU, QuikSCAT, TOMS, AVHRR, and OMI), and upper-air observations and numerical experiments with the WRF community model.
