EFFECTS OF THREE-DIMENSIONAL STRUCTURE OF HEATING FIELD ON THE SUMMER MONSOON CIRCULATION IN ASIA

In this paper,a primitive equation linear wave model is used to examine the effects of three-dimensional structure of heating field on the behavior of stationary planetary waves in summer and to compare the roles of different heating functions for the formation and maintenance of summer monsoon circulation in Asia.It is shown that the aloft heating connected with the latent heating,especially the deep condensation heating associated with the cumulus convection in low latitudes,plays a crucial part in the Asian summer monsoon and the structures of planetary wave responses are quite sensitive to the vertical distribution of heating.
