Description
Summary:Numerical simulations of four mountain wave events over the Colorado Rockies were carried out with a two-dimensional hydrostatic model including a turbulent mixing parameterization in order to investigate the effect of surface friction. Surface friction was found to play a major role in modulating and even in some cases preventing the wave amplification mechanism from producing severe downslope windstorms.
