摘要
本文通过滑动相关普查方法，对山西30个代表站点的夏半年(6～11月)降水与前期74个环流特征量及北太平洋海温月平均资料作逐点逐月普查相关分析。结果表明：上年7～10月的南方涛动指数及赤道东太平洋(EL nino区)海温与我省夏半年降水分别有很好的相关关系，它们的出现对山西夏半年降水影响是非常强的，同时还发现前期多个环流指数如太阳黑子、西太平洋副高与我省夏半年降水也有很好的相关关系。
In this Paper, We made a monthly correlation analysis between precipitation at 30 stations of Shanxi province in summer half year and prophase 74 circulation indexes and Pacific SST monthly mean value per point with generally running correlation method. The result shows that the southern oscillation index from July to October last year and the eastern equatorial Pacific SST have distinct correlation with the precipitation at Shanxi province in summer half year. Their influence to our province's precipitation is very strong and so are many circulation indexes, sunspot and the western pacific subtropical high.
