| 摘 要： | 根据云南省１９５１－１９９０年１８个站的降水资料，用正交函数展开，由方差贡献最大的前三个特征向量场分析了云南省降水距平均的典型分布，指出云南省全省范围内的降水距平同号较少发生，而是较多的发一降水距平异号。进而分析了四十年降水的年际变化特征，并分析了青藏高原积雪对云南降水的影响。

| Abstract: | According to the precipitation of 18 stations in Yunnan province during 1951 to 1990,the characteristic distribution of precipitation anomaly field was analysed by using the first three characteristic vector fields of orthogonal functions. It was pointed out that there were different anomalous signal in different precipitation region in many cases. The precipitation change chAracters in recent 40 years was analysed year by year. And it was discussed that the snow cover of Tibetan plateau influenced on the precipitation of Yunan province. |
