Description
Summary:Colle utilizes the fifth-generation Pennsylvania State University-National Center for Atmospheric Research mesoscale model in a two-dimensional configuration at 4-km horizontal grid spacing in order to better understand the relationship between orographic precipitation and the height and width of a barrier, as well as the ambient flow, uniform moist static stability, and freezing level. He focuses on how these parameters affect the orographic precipitation by changing the circulation and microphysical structures over the barrier. He points out that the precipitation distribution is highly dependent on how the terrain-induced gravity wave modifies the circulation aloft.
