A surface mesoscale wind model for complex terrain



A mesoscale model of the surface wind distribution over complex terrain is described. It is designed to simulate the time as well as the geographical variations of the wind field. The model equations incorporate the effects of nonuniformities in surface temperature, roughness, and terrain elevation. Initial integrations of the model equations have been made to simulate flow patterns in the vicinity of an isolated hill and over coastal regions during the occurrence of a sea breeze. The results of the integrations indicate that the model is potentially useful for studying flow over complex terrain.
