In the past my research interests have
involved topographically forced boundary layer flows, storm-coast interactions,
snowstorms in the Pacific Northwest, satellite signatures of maritime
cyclones, and tropical-extratropical interactions. Some publications
on these topics are listed below.

Another project that I am involved with
concerns moisture transport in precipitating weather systems.
Latent heat release associated with precipitation can impact the dynamics
of the lower troposphere. This can lead to feedbacks between moisture
transport, precipitation, and storm structure. I am hoping to continue
research in this area over the next several months. This research was
initiated during my postdoctoral appointment at
McGill University in collaboration with Professor John Gyakum.
Some of my publications on this topic are listed below.
During my stint as a postdoc at
McGill University, I assisted with a project that investigated the
utility of using quasigeostrophic potential vorticity inversion to
diagnose hurricane track errors. By decomposing hurricane motion
into pieces associated with various synoptic features, it is possible
to quantify forecast errors. For Hurricane Opal, the errors were
mostly in the downstream ridge, which is consistent with the fact that
the eta model does not resolve the inner-core region of hurricanes
and the deep convection therein. A paper reporting these findings,
written by John Henderson, is currently in review:
Other
research interests and projects include study of lake-effect snow,
signatures of local Rochester-area thunderstorms and snowstorms, and
planetary-scale signatures associated with severe flooding. Stay tuned
for more information, and contributions from the undergraduate
meteorology students who are helping with the research.
