I am primarily interested in atmospheric dynamics, mesoscale numerical modeling, vortex dynamics,
high latitude meteorology and physics, climate modeling, and Arctic climate.
Recent work has sought to understand the physical mechanisms leading to vortex intensity changes in high-latitude,
sub-synoptic vortices, which we call tropopause polar vortices (TPVs). Generally located poleward of the midlatitude jet stream, these vortices are based on the
tropopause, can have lifetimes of over one month, and are observed to have nearly moist adiabatic atmospheric
lapse rates in the vicinity of the vortex core.
These vortices can ultimately have a significant impact on midlatitude weather when
they interact with the jet stream.
