| Abstract: | By numerical integration of the ecluation of the atmospheric boundary layermotion,a study is conducted of the influence of the horizontally nonhomogeneous, non-stationary disturbance of the free atmospheric (at the top of the boundary layer)wind onthe internalparameter u. /G (u. is the friction velocity and G the wind velocity of thefree atmosphere). Results indicate that in the parameterization of the large-scale modelboundary layer, owing to the non-stationariness and horizontal non-homogeneousnessof the large-scale wind pressure field there exist errors when the classic stationary,horizontally homogeneous resistance law is directly used. It is, therefore, necessary toconsider a revision of non-stationariness and non-homogeneousness as well as topo-graphic forcing. |
