THE NUMERICAL SIMULATION OF TWO-DIMENSIONAL DYNAMICAL CLIMATE MODEL WITH MOUNTAIN FORCING

In order to investigate the effects of trace gases on climate variation in the atmosphere,we have developed a primitive equation two-dimensional dynamical climate model with five levels.A series of simulation results and discussions are shown in this paper,indicating that the model is useful and can comectly reproduced the main feature of the general atmospheric circulation and its seasonal changes.In addition,we have discussed the role of the Qinghai-Xizang Plateau on the formation process of summer monsoon in South Asia and found that the thermal effect of the Qjnghai-Xizang Plateau may not be the main factor controlling the onset and the variation of the summer monsoon in South Asia.
