The Expressions for the Wind Profiles of Free Convective and Stable Boundary Layers and the Pumping Velocity at the Top of the Planetary Boundary Layer
|
Abstract:
Based on recent studies of the turbulent transfer in free convective and stable boundary lay -ers , analytic expressions for wind profiles in these two cases are obtained , the profiles and boundary layer parameters are in agreement with observational characteristics . Furthermore, the analytic expressions for the pumping velocity at the top of the PBL and their relations to some parameters are also derived . The results show that the pumping velocity is connected with stratification and may be explained physically.
