Projects:
Tropical Cyclone Intensity and
Structure:
Current research efforts are
directed toward better understanding the
various mechanisms that control the timing, location, and
intensity of convection in the tropical cyclone core.
Our primary approach is through extensive analysis of a wide
variety of aircraft-based observations (e.g. Doppler radar, GPS dropwindsondes, and traditional flight-level data). The
observational results will then be compared to any theoretical
expectations or previous numerical simulations of tropical
cyclones.
This research is funded through a
grant from the National Science Foundation (NSF ATM-0652264) in
collaboration with Dr. Paul Reasor at Florida State University,
Dr. David Nolan at the University of Miami, and Dr. Frank Marks
at the NOAA Hurricane Research Division.

Tornado
Formation in the Outer Rainbands of Landfalling Tropical Cyclones:
Current research efforts are
also directed toward better understanding the
various mechanisms and conducive environments that lead to
tornado formation in the rainbands of landfalling tropical
cyclones. Our primary approach is through extensive analysis of aircraft
and land-based observations (e.g. Doppler radar, GPS dropwindsondes,
rawindsondes, and traditional flight-level data). This
project is in its preliminary stages.

Surface
Observations in Outer Rainbands
of Tropical Cyclones:
Current research efforts are
also directed toward better understanding of the frequency and
magnitude convective downdrafts and outflow boundaries associated
with tropical cyclone rainbands. Such events may promote the
baroclinic enhancement of miniature supercells and the tornadoes
they often spawn during a landfalling tropical cyclone. Our primary approach is through extensive analysis of
coastal surface and radar observations. This
project is in its preliminary stages.
This research is primarily funded through a
grant from the University of North Carolina at Charlotte (UNCC)
with additional support from the Renaissance Computing Institute (RENCI)
and the communities of Brunswick County, North Carolina.
