Our primary interests are in tropical, mesoscale, and radar meteorology. A central focus of our research is studying the mesoscale structure and intensification of tropical cyclones throughout their life-cycle from genesis to extratropical transition. This research is accomplished through the collection and analysis of research quality observations from aircraft and Doppler radars, in conjunction with high-resolution numerical modeling. A significant component of our research effort is also aimed at improving mesoscale and radar analysis techniques and open source software tools.
