Research Interests
In general, I am interested in dynamic meteorology at all scales
and the mathematical and computational tools used to study such
motions. My research projects have included sea and
lake breeze circulations, mountain meteorology, boundary conditions for numerical models, and numerical model development.
My current research is an investigation into the boundary conditions used for nested grids in mesoscale models. I am looking to determine whether the standard boundary conditions used are indeed appropriate for all situations, and if not, whether suitable alternatives can be found. A hierarchy of models is proposed to study this problem.
My prior research involved the observation and modeling of
shedding lee vortices ("Von Karman vortex streets") and the determination of
the atmospheric conditions which would make shedding more likely. These factors
include the presence of an inversion layer and the existence of lower
tropospheric wind shear. The role of flow evolution and kinematics was also studied, as well as what factors favor the development of
cyclonic or anticyclonic vortices.
