Simulation of the Land Surface Processes in the Western Tibetan Plateau in Summer

WANG Cheng-hai,SHI Rui (Key Laboratory of Western China's Environmental Systems,College of Atmospheric Sciences,Lanzhou University,Lanzhou Gansu 730000,China)  
The observational data from 1 May to 18 September 1998 collected by Automatic Weather Station installed in Shiquanhe of the Western Tibetan Plateau are analyzed.The land surface processes on the Tibetan Plateau are simulated by an improved land surface model(Common Land Model),which can present the surface thermal condition tendency under observation data forcing.In the Western Tibetan Plateau,the sensible heat flux dominates the heat energy balance in summer,followed by the latent heat fluxes.But during the rain season,the latent heat flux can not be ignored.Phase change of surface soil water takes place often,resulting in soil absorbing and releasing latent heat frequently.Moreover,surface-released effective thermal fluxes(sensible and latent heat) follow the change in precipitation,freezing and thawing,and so does their Bowen ratio.As a result,the situation of atmosphere heating and transportation of atmospheric vapor will be affected.In return,the changed atmosphere will affect the soil water content due to the variation of land surface evapotranspiration and soil water containing capacity.
