| 摘 要： | 2007年9月下旬中期-10月上旬，晋西北地区出现了过程雨量最大、持续时间最长的秋季连阴雨天气过程，致使气温持续偏低，日照寡缺，地表积水严重，给当地的工农业生产造成严重影响。本文利用2007年9月下旬-10月上旬的气象观测资料，从高低空形势、风场特征、水汽条件等方面对2007年9月26日-10月10日秋季连阴雨进行初步分析发现，2007年我国北方秋季发生长时间的连阴雨与赤道中东太平洋海温有重要关系。2007年秋季北方降水异常型表现出了典型的La Nina的影响。

| Abstract: | duration in late There was September once autumn continuous rain which had maximum process rainfall and produced longest beginning October 2007 in northwest Shanxi. It caused the continued low temperature, little sunshine and serious surface water. It seriously impacted on industry and agriculture. This continuous rain was analyzed based meteorological data in upper and lower situation, wind characteristics and moisture conditions. The results show that the continuous rail in autumn 2007 related with SST in the tropical central eastern Pacific. The anomaly precipitation in autumn 2007 showed typical La Nina impact. |
