This is a regional (mesoscale) weather simulation model developed for the Western United States. This model was developed to specifically examine airflow and precipitation over mountainous areas in California (Kim and Soong, 1994). It is used to predict future precipitation, cloud cover and evapotranspiration. The model requires as input either the output from a GCM or regional weather values of pressure, wind speed and direction, temperature and water vapor. Two related models comprise the mesoscale model; a hydrostatic model and an atmospheric convection model. The hydrostatic model also contains a simulation component that includes soil and boundary layers.
