Biography

Larry Berg conducts studies to investigate the behavior of the atmospheric boundary layer in rural and urban areas using both field measurements and regional weather prediction models. Specifically, Dr. Berg's research addresses questions related to the nature of turbulence in the atmosphere, boundary-layer clouds, and air pollution dispersion in urban areas. Results from these studies have led to the development of a new parameterization to represent fair-weather clouds in both global and regional scale models, and a modified regional prediction model coupled with an applied dispersion model for use in areas of complex terrain.

Research Interests

  • Atmospheric aerosols in global climate models
  • Processing and transport of atmospheric aerosols by clouds
  • Parameterization for fair-weather cumuli
