中文摘要:
      分析了1983年江淮流域梅雨期及其前后亚洲季风区平均散度风环流和垂直积分水汽输送的辐散分量。在入梅前强水汽辐合中心位于华南,出梅后则位于印度季风区,梅雨期这两地区都存在着强水汽辐合中心,并且强水汽辐合区和中国东部雨带的位置变化及热源分布有着密切关系。同时指出,江谁流域梅雨与大尺度辐散环流的变化、热源的配置及水汽辐合的位置有着较好的对应关系。
英文摘要:
      In this paper, the mean divergent circulation and the divergent component of the vertically integrated moisture flux over the Asian monsoon region before. during and after raining season(Mei-yu) in 1983. are analysed. Before Mei-yu the stronger convergence center of the moisture flux is located over southern China and after Mei-yu period over the Indian monsoon regions. During the Mei-yu period two strong moisture convergence centers over the Indian and East Asian monsoon regions could be observed. The strong convergence zones of the moisture flux are closely related to the variation of the rainaera over the eastern China and the distribution of the heat source. Also, the results show that there are fairly good corresponding relationship between Mei-yu over the Changjiang and Huaihe River Basin and the change of large scale divergent circulation. disposition of heat source and the distribution of the moisture flux convergence.
