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

本文利用原始方程线性波模式考察了加热场的三维结构对夏季定常行星波特性的影响;比较了不同加热方式对亚洲夏季风坏流的形成及维持所起的作用。指出与低纬深厚积云对流相联的凝结加热对亚洲夏季风环流所起的重要作用和大气定常行星波响应对加热场的垂直结构的敏感性。

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 healing functions for the formation and maintenance of summer monsoon circulation in Asia. It is shown that the aloft heating connected with latent heating, especially the deep condensation heating associated with cumulus convection in low latitudes, plays a crucial part for the Asian summer monsoon and the structures of planetary wave responses are quite sensitive to the vertical distribution of heating.
