| 摘 要： | 本文利用多年月平均印度洋海表温度资料和我国160站点降水资料,通过奇异值分解(SVD)方法,分析了印度洋东西海温信息区温度差值与我国同期降水场之间的耦合关系,得到奇异向量分布型及相互作用的耦合周期信号。在对第一主模态的分析中发现印度洋海温分布对我国降水分布和降水强度有很大影响,且对各季影响存在一定差异。

| Abstract: | Based on the monthly data of SST of the Indian Ocean and the rainfall data from National Climate Center, the relationship of rainfall in China and differences of SST of western and southeastern India Ocean is analyzed by singularity value decompose(SVD) method. The distribution of the singularity vectors and the coupling cycles are obtained. It is found that the distribution and the intensity of rainfall in China is greatly affected by the distribution of SST of the India Ocean, and the effect is different in different seasons, according to the analysis of the first mode. |
