摘要
本文通过相关分析和相关场的显著性检验,发现前一年夏季赤道东太平洋海温偏高(埃尔-尼诺持续或正在生成),次年夏季海温降至负距平(埃尔-尼诺结束),这时我国北方从河套向东直至渤海之滨的广大地区6～9月降水偏多,反之前一年夏季赤道东太平洋海温偏低,次年海温升高(埃尔-尼诺将生成),这时我国北方广大地区干旱少雨。同时发现印度夏季风雨量、春季西太平洋海温都与我国北方广大地区夏季降水量显著正相关。这表明埃尔-尼诺可能通过对西太平洋副高的作用及对印度夏季风的作用等多种途径影响我国北方夏季降水。
In this paper, the correlation of SST over equatorial East Pacific region with the rainfall during June-September in China has been made, and that of Indian summer monsoon rainfall with the summer rainfall in China has also been made.
The correlation fields have passed 95% significance test. It is shown that when SST over equatorial East pacific region is warmer(EI Nino), the rainfall during June-September over the vast area in northern China is less than normal;if the SST over equatorial East Pacific region becomes colder in the next year (El Nino ending) , the summer rainfall will be more than normal over the extensive area in northern China. And it is shown that Indian summer monsoon rainfall is significantly correlated with the concurrent rainfall over the most part of northern China.
