Broadly, I am interested in tropical cyclone and mesoscale convective system structures, dynamics, and evolutions on scales ranging from the mesoscale to the climate-scale. I utilize theory in conjunction
with available observations and numerical modeling, particularly ensembles, to obtain physical and dynamical insight into these features. I firmly believe that the best way to advance the science is to actively follow the
weather on a daily basis, examine events and scenarios that occur that we do not fully understand, and rigorously analyze them using all available methods.
My current research focuses upon a wide array of related topics, including but not necessarily limited to the following:
- The extratropical transition of tropical cyclones, including the
structural evolution of the cyclone's thermodynamic profile & wind
field
- Atypical tropical cyclone evolutions, including the overland reintensification of Tropical Cyclone Erin (2007)
- Vortex dynamics on multiple scales, particularly associated with the development of mesolows with mesoscale convective systems
- Diagnosis and verification of tropical cyclone structures within real-time NWP models
- Evaluating the utility of physics- and initialization-based mesoscale ensembles
- The role of tropical cyclones in climate, particularly tropical-extratropical interactions
Past research topics and interests include the predictability of higher latitude impacts of tropical cyclones and diagnosis of weather features using GPS-based remote sensing retrievals. I actively collaborate
with a number of scientists at NCAR and elsewhere, including R. Hart (FSU), R. Schumacher (Texas A&M), T. Galarneau (Univ. at Albany, SUNY), M. Weisman (NCAR), K. Manning (NCAR), C. Davis
(NCAR), and G. Bryan (NCAR), and am always eager to work with other scientists on exciting new topics. Please feel to contact me if you are interested in any of these or other related topics.
