| 摘 要： | 本文应用四川盆地23个站的年降水资料、太阳黑子相对数与西北太平洋副高强度指数资料,分析太阳黑子活动的异常与四川盆地降水的联系,认为:四川盆地东西部降水量呈振荡型、这种振荡型可能是太阳活动通过西北太平洋副高的作用而激发的、时间上有滞后一年以上的特性,即太阳黑子活动的强弱、引起西北太平洋副高强度的变化,进而影响四川降水的东西分布特征。反映为太阳黑子偏多年分,第二年的西北太平洋高压偏强、相应四川盆地降水呈西涝东旱型、反之亦然。

| Abstract: | A statistical analysis of the lag correlation among the sunspot action, the North-West Pacific subtropical high intensity index and the precipitation in Sichuan basin is performed in this paper.
According to the statistical analysis, it may be noted that: The precipitation distribution in Sichuan basin has a osillation pattern. The sunspot action first effects the North West Pacific subtropical high, the lag time is one to two year. Then the subtropical high effects the precipitation distribution in Sichuan basin at the same time, the lag time is also one to two year. In the lag correlation fields between the sunspot and precipitation, there exist two correlation centers, Emei is positive value center and Jiangjin is negative center. |
