Summary

Atmospheric science, mesoscale and synoptic meteorology. Research on coastal low-level jets, coastally trapped wind reversals, and the marine atmospheric boundary layer.

Research

My research areas reflect my interest in mesoscale features including low-level jets, coastally trapped wind reversals, and coastal lows. I also investigate the synoptic and large scale influences on the lower atmosphere with special attention to the response of the marine atmospheric boundary layer. These topics are explored through observations (including several field campaigns that involved aircraft and radiosonde measurements) in conjunction with numerical simulations.
