应用谱分析方法，讨论了云南省降水与赤道西太平洋（ １０°Ｓ～ １０°Ｎ， １２０°Ｅ～１６０°Ｅ）海表温度的关系。结果表明，云南省降水与赤道西太平洋海温 在３个月，５个月及１８．４月的振动周期上有很好的耦合关系。对于１８．４个月 的周期性振荡，云南省降水落后赤道西太平洋海温３个月，且降水对海温的响 应是由西向东传播。
The relationship between precipitation and the sea surface temperature in the western equatorial Pacific (10 ° S ~ 10 ° N, 120 ° E ~ 160 ° E) in Yunnan Province was discussed using spectral analysis method. The results show that there is a good coupling relationship between precipitation and the SST in the western equatorial Pacific during 3 months, 5 months and 18.4 months. For 18.4 months of periodic oscillations, precipitation in Yunnan Province lagged behind the equatorial Pacific SST for three months and the response of precipitation to SST was transmitted from west to east.
