| 摘 要： | 采用海温、降水、OLR和NCEP／NCAR40a再分析资料，利用REOF方法，研究了夏季北半球海温异常(SSTA)的变化特征，结果显示：第4个REOF空间型是黑潮海温异常的典型形态。相关、合成分析表明，夏季黑潮海温正异常年时，长江流域降水偏多，洞庭湖流域显著偏多；负异常年时则反之。

| Abstract: | Based on the data of SST,rainfall in China,OLR and NCEP/NCAR 1958-1997 reanalysis data,the spatial/temporal variations of SSTA in the Kuroshio current region and its relation to summer precipitation in China have been analyzed by using the REOF method in this paper.Results show that there is an striking interdecadal change in SSTA,and the 4th-REOF spatial mode is a typical pattern for SSTA in the Kuroshio region.Correlation and composite analysis both show that there is more(less) rainfall in the Yangtze River in the positive(negative) anomaly year,especially in the Dongting Lake Region. |
