Research Highlights

Research Interests

Dynamical processes involved in tropical cyclone vortex organization from the incipient stage to hurricane formation, particularly in environments where vertical wind shear is a significant dynamical forcing of the fluid system. 

Developing new ways of collecting and analyzing airborne radar observations of the convective-vortex flow during this critical, and often difficult to forecast, stage of a tropical cyclone’s life cycle.

“I really can’t remember a time when I didn’t want to be a scientist. I do distinctly remember as a kid reading some of the Faraday Lectures and thinking that it would be great fun to be a scientist! I suppose as I navigated through the various sciences, from geology to chemistry to physics, there was a natural curiosity about how things worked, and an excitement with finally understanding, that kept me motivated. But when I hit meteorology, I started to have great fun, and it was settled.”

Dr. Paul Reasor is a research meteorologist in the Hurricane Research Division of NOAA’s Atlantic Oceanographic and Meteorological Laboratory in Miami, Florida. His primary research falls under the division’s Hurricane Dynamics and Physics theme, and focuses on understanding the impact of vertical wind shear on hurricane structure and intensity change, using a combination of theory, numerical modeling and aircraft observations. He also works under the Observing Techniques theme on airborne Doppler-radar quality control and analysis techniques.
