中文摘要：
热带西方的太平洋(TWPO ) 的海表面温度(SST ) 显示出在 1990 年代末的显著温暖。用一个地区性的气候模型(RegCM ) 的数字实验，我们分析了这在 Meiyu 时期期间在中国的 Yangtze-Huaihe 河山谷上在降雨上温暖的影响(JuneJuly ) 。模型结果表明自从 1990 年代末，在 Meiyu 降雨的观察十的变化能被观察 SST 强迫的一个控制实验复制。另外，敏感实验建议在 TWPO 的温暖的趋势起了一个实质的作用在向北方在 1990 年代末 Meiyu 带变。
英文摘要：
The sea surface temperature （SST） of the tropical western Pacific Ocean （TWPO） showed a pronounced warming in the late 1990s. Using numerical experiments of a regional climate model （RegCM）, we analyzed the impact of this warming on rainfall over the Yangtze-Huaihe River valley of China during the Meiyu period （June July）. The model results revealed that the observed decadal changes in Meiyu rainfall since the late 1990s can be reproduced by a control experiment forced by the observed SST. Additionally, the sensitivity experiments suggested that the warming trend in the TWPO played a substantial role in the northward shift of the Meiyu belt in the late 1990s.
