摘　　要：应用谱分析的方法,讨论了东南亚降水分别与热带印度洋和太平洋海温的关系.得出热带印度洋和太平洋海温变化对东南亚降水影响的最佳落后时间长度.同时找出了上述2片海域对东南亚降水影响的几个关键区,它可以作为东南亚旱涝预报的强信号因子.The calculation method of spectrum analysis,the correlation analysis between the sea temperature on tropical Pacific and Indian Ocean and the rainfall in Southeast Asia is discussed.The results indicated the best lasted time and the key sectors that the rainfall in Southeast Asia influenced by the sea temperature on tropical Pacific and Indian Ocean.The strong signal phenomena of SSTA over tropical Pacific and Indian Ocean were revealed and it showed that the precipitation may be forecasted by analyzing the key sectors.
