Impact of the Atmospheric Boundary Layer on Mountain Waves

摘要: Abstract Interaction between mountain waves and the atmospheric boundary layer (BL) has been investigated using a mesoscale model with BL parameterizations analytical models. The impact of diagnosed from simulations is in qualitative agreement In general, for stratified flow over ridge, influence tends to shift wave patterns upstream, decrease drag by up 60% momentum flux above top 80%, significantly delay onset breaking. It demonstrated that effect governed four nondimensional parameters, namely, depth, shape factor, nonhydrostatic parameter, frictional adjustment parameter. stronger rougher surface, which creates deeper smaller factor (i.e., slower flow). scale dependence parameters.
