| 摘 要： | 本文详细地讨论了厄尔尼诺与我国汛期大尺度降水的关系。指出,厄尔尼诺东部型,北太平洋海温的三个主要正负距平区的结构具有PNA遥相关型;厄尔尼诺中部型,北太平洋海温的三个主要正负距平区分布在赤道东太平洋到千岛群岛一线上。进而指出,厄尔尼诺东部型峰期过后,我国汛期降水的大尺度特征是长江流域降水偏少,江南和华北地区降水偏多。在厄尔尼诺中部型峰期过后则相反,长江流域降水偏多,江南和华北降水偏少。

| Abstract: | In the paper, the relationship between ElNino and rainfall during the flood season in China is discussed. when the east-pattern of El Nino, the structure of three major positive/negative SST departure regions in Northern Pacific are very similar to the PNA-pattern, and the rainfall during the flood season is less than normal in Changjiang River Valley and is more than normal in north China and south of Changjiang Valley. When the middle-pattern of El Nino, the three major positive/negative SST departure regions are distributed over the line from the Equatorial Eastern Pacific to Kurile Islands, and the rainfall during the flood season is more than normal in Changjiang Valley and is less than normal in north China and south of Changjiang Valley. |
