江淮流域夏季降水与全球海温异常关系分析

利用1951 ～2009年中国160站降水资料和1951 ～2009年NCEP/NCAR再分析资料月平均的海温格点资料,拟通过一元线性回归、相关分析方法、合成分析方法研究江淮流域夏季降水与全球海温异常的关系.结果发现,西北太平洋、北大西洋、印度洋南部海区为海温关键区,江淮流域夏季降水异常与这3个关键区的海温异常存在良好的正相关关系,尤其西北太平洋前期冬季、北大西洋前期冬季、印度洋南部前期春季在3个海区中最为显著.

Analysis on the Relationship between Changjiang and Huaihe River Basin Summer Rainfall and Global Sea Surface Temperature Anomalies

Using the monthly precipitation data from 160 stations of China from 1951-2009 and the NCEP/NCAR reanalysis monthly mean sea surface temperature point data from 1951-2009,applying the way of simple linear regression,correlation analysis method and composite analysis method to study the relationship between Changjiang and Huaihe River basin summer rainfall and global sea surface temperature anomalies.The results showed that the Northwestern Pacific,the North Atlantic and the south of Indian Ocean are the key areas of sea surface temperature.There are good positive correlations between Changjian and Huaihe River basin summer rainfall anomalies and the sea surface temperature anomalies of the three key areas.Especially the early winter of the Northwestern Pacific,the early winter of the North Atlantic and the early spring of the south of the Indian Ocean are the most significant.
