Monte-carlo Model simulates the Influence of Complex Terrain on Diffusion

Tian Ruiming(Institute of Atmospheric Physics, Chinese Academy of Sciences. Beijing 100029)  
Not considering the stratification, using the mean flow pattern over complex terrain obtained byKao and the turbulence statistics parameterization derived from the experiment and theory in the PBL,the innuence of complex terrain on diffusion is simulated with a Monte-carlo model in this paper.Theresults are:the main influence of terrain is lifting and sinking motion over the windward side andleeward side of the terrain,respectively;the abrupt the terrain,the larger the closed concentrationcenter, the influence of a larger terrain may override that of a smaller one.
