这研究在华中上调查了在澳大利亚的夏天季风(ASM ) 和夏天降水之间的连接。它被发现那,跟随 weaker-than-normal ASM,东方亚洲夏天季风和西方的向北和平的副热带的高度趋于更强壮,让步异常向北方从西方的太平洋要搬运到华中的潮湿。而且,异常 upwelling 运动超过 3037.5 出现
This study investigated the connection be- tween the Australian summer monsoon (ASM) and sum- mer precipitation over central China. It was found that, following a weaker-than-normal ASM, the East Asian summer monsoon and western North Pacific subtropical high tend to be stronger, yielding anomalous northward moisture to be transported from the western Pacific to central China. Besides, anomalous upwelling motion emerges over 30-37.5°N, along 110°E. Consequently, significant positive summer precipitation anomalies are located over central China. Further analysis indicated that the boreal winter sea surface temperature (SST) in the Indian Ocean and South China Sea shows positive anomalies in association with a weaker-than-normal ASM. The Indian Ocean warming in boreal winter could persist into the following summer because of its own long memory, emanating a baroclinic Kelvin wave into the Pacific that triggers suppressed convection and an anomalous anticyclone. Besides, the abnormal SST signal in the South China Sea develops eastward with time because of local air-sea interaction, causing summer SST warming in the western Pacific. The SST warming can further affect East Asian atmospheric circulation and pre- cipitation through its impact on convection.
