南方涛动与赤道太平洋海温和信风的耦合振荡

本文采用多维谱分析方法，用南方涛动指数与赤道东太平洋海温、信风指数分别进行计算分析，从中揭露了南方涛动和赤道太平洋海温的耦合振荡过程。它们的变化不仅基本上是反位相，而且存在着明显的时间差异。此外，本文还分析了南方涛动与信风的相关性。

The Coupling Oscillation Between the Southern Oscillation and the Sea Surface Temperature and Trade Wind

In this paper, by using multi–spectral analysis, some factors such as the southern oscillation index, sea surface temperature and trade wind index have been calculated, and the coupling oscillation between the southern oscillation and the sea surface temperature over the equatorial Pacific is revealed. It is found that their variations are seemed to be out of phase, and there is a few months phase difference between the sea surface temperature and the southern oscillation. In addition, the correlation between southern oscillation and the trade wind over the Pacific is analysed.
