摘要
根据1979~1998年中国夏季(6~8月)逐月降水资料和同期的印度洋海温资料,分别运用经验正交函数和奇异值分解的方法,分析了我国夏季降水的时空分布及其与同期印度洋海温之间的联系。结果表明,我国夏季逐月降水存在着几种相对典型的空间分布形态;夏季印度洋海温与同期江淮流域降水之间呈正相关,而与我国其他大部地区降水之间呈负相关。
Using the monthly mean summer ( June to August) precipitation in China from 1979 to 1998,and the SST in Indian Ocean of the overlapping periods,the empirical orthogonal function and singular value decomposition methods were used respectively,the relationships between the precipitation in China and the SST in Indian Ocean were analyzed. The results showed that several canonical anomalous summer precipitation patterns had been identified.The summer SST in Indian Ocean had positively correlated with the simultaneous precipitation in the Yangtze River and Huai River Basin,while negatively with that in other parts of China.
