| 摘 要： | 本文从分析阿拉伯海至南海海温距平场为东暖西冷和东冷西暖两种不同纬向分布型时热带大气环流不同的特征中讨论了该区海温异常对长江中下游梅雨影响的物理过程。指出不同类型的海温距平纬向分布,可能导致印度季风和东亚季风位置和强度不同的变异,并通过这两支季风的相互作用和调整,影响西太平洋热带辐合带、副热带高压和我国降水的分布。

| Abstract: | In this paper, the difference of tropical circulations is analyzed for the two different types of zonal distributions of sea surface temperature (SST) anomaly in the Arabian Sea and the South China Sea. The physical processes for the effect of zonal difference of SST anomalies in that oceanic area on the summer rainfall over the lower and middle reaches of Yangtze River are discussed. It is suggested that different types of zonal SST anomaly distributions may result in different variations in position and intensity of main components of the Indian and the east Asian monsoon systems, and lead to different distributions of the ITCZ and subtropical high over the western North Pacific, the summer rainfall in East China, through the interaction and adjustment between the two monsoon systems. |
