In the paper,we have developed a 2-D physical-dynamical coupled climate model.Some sensitive experimentshave been done by use of this model.First of all,we have studied the effects of different results by two radiational calcu-lation schemes on circulation variation.The calculated results have shown that the different radiation parameterizationschemes give different results,therefore the variational effects of wind,temperature,and humidity field are presented onthe medium-range circulation variation.Besides,we have also studied the role of the meridional eddy momentum fluxes in formation of the monsoon overEast Asia.The results of study have shown that on the average,the roles of meridional eddy flux of momentumformative processes of monsoon which is added to momentum equations by using the scheme of moist processparameterization with plateau are manifest.
