Professional Interests

My current research interests involve the atmospheric boundary layer and its interaction with the surface and clouds; and the structure of deep precipitating convection and its effect on momentum. In my early career, I combined numerical models and observations to study the structure of and transports through the fair weather planetary boundary layer and its interaction with clouds.Starting around 1980, I became interested in the generation and transport of momentum by lines of deep convection, using aircraft and Doppler-radar observations, and comparing the results of these and other case studies to idealized models. Most recently, I have returned to boundary-layer research, with an emphasis on the effects of surface properties (vegetation, soil moisture, soil properties, terrain) on the evolution of the atmospheric PBL. I have extensive experience in field programs, having participated in GATE, PRESTORM, TAMEX, STORM FEST, and TOGA-COARE, CASES-97, CASES-99, and IHOP. I am a Fellow of the American Meteorological Society, the American Association of the Atmospheric Sciences, and a member of the National Academy of Engineering. In addition to my scientific activities, I have written several popular articles on weather, including a booklet on clouds published by the AMS and the weather portion of a high-school textbook, and have been involved in educational outreach for over 30 years.
