中文摘要:本文对东太平洋海温异常(SSTA)与西太平洋副高活动及中国夏季台风降水的关系进行了相关分析。结果表明:前期东太平洋海温异常增暖时,我国夏季台风降水量呈“南多北少”,反之,则是“北多南少”。台风降水量分布型对SSTA的这种关系,可认为是厄尔尼诺事件引起的大气环流变化,从而影响西太平洋副高和台风发生源地及移动路径的结果。

RESPONSE OF SUMMER TYPHOON RAINFALL IN CHINA TO SST VARIATION OF THE EAST PACIFIC
Abstract:The correlation of the sea surface temperature anomaly (SSTA) of the East Pacific with the activities of subtropical high pressure in the West Pacific and the tythoon cyclonic precipitation in China is analyzed in this paper. Results show that summer typhoon rainfall in China is plentiful in the south and scarce in the north when the sea surface tem-perature (SST) of the East Pacific increases anomalously, and reverse situation occurs when the SST decreases. The dependence of the typhoon rainfall distribution pattern on the SSTA can be attributed to the variation of the atmospheric circulation caused by the E1 Nino event, thus influencing the activities of subtropical high pressure and tropical cyclones.
