| 摘 要： | 应用滑动Ｔ检验方法对北太平洋海温１０年际的气候跃变进行了研究，指出在７０年代末至８０年代初确实存在着一次明显的气候跃变，而跃变前后北太产洋海温结构，厄尔尼诺事件的发展过程都明显不同，进而讨论了北太平洋海温跃变前后对我国６－８月汛期降水量的影响，指出海温跃变前我国汛期降水量在东北地区偏少，华北偏多，长江流域偏水，华南偏多，而跃变后则相反。

| Abstract: | Studying annual climatological jump of SST in northern Pacific by means of the method of moving T test,an obvious climatic jump is indicated to be present late 1970's through early 1980's and there are significant difference befor and after the jump in terms of its SST structure and evolutionary processes of El Nino event.The discovery is then based to study the effect of the jump on rainfall in June-August floods season in China,concluding that the season precipitation is less(more) than usual in the northeast of China and Changjiang River Basin(north and south of China) before the jump and vice versa. |
