Air-sea interactions, satellite meteorology and oceanography, atmospheric boundary layer and ocean mixed layer dynamics.
Currently I am working on characterizing the divergence variability from scatterometer observations. I also am working with colleagues at the Naval Research Laboratory to use numerical weather prediction models to better understand what physical processes shape the observed divergence variability. We are also continuing research into understanding how sea surface temperature variability affects the surface wind field, including the divergence field. Finally, I am also continuing work to understand how clouds and rainfall are affected by variability in the near-surface divergence field.
