| 摘 要： | 为了解近50年来东南沿海地区降水与海温变化的关系，对该地区降水与全球海表温度进行了奇异值分解（SVD）。结果表明：印度洋、南海及赤道东太平洋地区是对东南沿海地区降水有影响的关键区域。东南沿海地区秋冬季的降水总体上来说对前期海温变化的响应不敏感，而东南沿海地区夏季降水受前期海温的影响较为明显，尤其是上年夏季北印度洋、南海地区海温的变化对当年降水有明显影响。因此，在预测东南沿海地区夏季降水时应该重点考虑上年夏季北印度洋及南海地区海温的变化情况。

| Abstract: | The precipitation variation over Southeast China during recent 50 years and its relationship with SST are analyzed by using the SVD (Singular Value Decomposition) method. The results show that the India Ocean, South China Sea and the eastern Pacific Ocean were key regions for influencing the precipitation over Southeast China. The autumn and winter precipitations over Southeast China were not strongly affected by the SST of previous months as a whole, while there is marked negative relationship between the summer precipitation and the previous summer SST, especially in North India and the South China Sea. |
