| 摘 要： | 本文分析了1983年江淮流域入梅前、梅雨期以及出梅后东亚地区各期平均的经向环流结构及其演变特征。在不同时期,印度热带季风环流和东亚热带及副热带季风环流具有显著差异。研究指出,江淮流域梅雨是亚洲夏季三个季风系统相互作用的结果,是东亚副热带季风系统中经向环流上升支中的产物,同时又与其它两个季风系统密切相关,梅雨结束则与印度热带季风环流减弱南撤、西太平洋高压加强西伸、东亚副热带季风环流北上有关。

| Abstract: | In this paper, the structure of the mean meridional circulation and its evolving features over East Asia before, during and after the Mei-yu season for the Changjiang and Huaihe River Basin in 1983, are studied. For different periods, the circulation of the Indian tropical monsoon and the East Asia tropical and subtropical monsoon differ significantly. The research shows that the Mei-yu for the basin results from the interactions among the 3 summer monsoon systems in Asia. Its onset is a consequence of the ascending branch of the meridional circulation in the East Asia subtropical monsoon system, closely related with 2 other monsoon systems. Its ending has something to do with the southward withdrawal of the weakened Indian tropical monsoon circulation, the westward extension of the increased West Pacific High, and the northward advancement of the East Asia subtropical monsoon circulation. |
