60年代我国夏季气候跃变及其与海温的相互联系

根据气候跃变概念，结合主相关型和经验正交函数（ＥＯＦ）的分析，揭示了６０年代我国汛期降水、夏季气温和海表水温大规模变化的主要时空分布特征。指出不同地区和不同要素的气候跃变在时间上和强度上不太相同，海表水温的跃变先于气温和降水的跃变；夏季气温、汛期降水与１月海表水温落后两年相关密切，呈正相关关系。

SUMMER 1960s CLIMATE JUMP IN CHNA WITH ITS RELATION TOSST

Following the concept of climate jump based on the principal teleconnection patternand EOF analysis,salient temporal and spatial features are revealed of the wet-season rainfall andsummer temperature on a large scale over China in relation to SST in the 1 9 6 0s,Results showthat the jump is somewhat different in time and strength from region to region and from elementto element;jump of SST preceded that of air temperature and rainfall;the summer temperatureand rainy-period precipitation bore a close positive correlation to January SST on a twoyear-lagbasis.
