对陕西2000年7月13日紫阳和镇巴暴雨、2002年6月8日佛坪暴雨及2003年8月23日～10月4日渭河流域(二华夹槽地区)的连阴雨中的暴雨从环流形势场进行了对比分析,认为,在不同天气气候背景下都有可能出现大的洪涝灾害,只有提高防范意识,才可以减轻灾难造成的结果。

The comparative analysis is made on the circulation pattern fields of the three rainstorms occurred respectively on July 13th, 2000 in Ziyang and Zhengba, on June 8th 2003 in Fuping and in the period from August 23rd to October 4th in 2003 in Weihe valley where cloudy and rainy weather lasted. The results show that the great flood and waterlogging damages may take place in the different synoptic and climate background. Only improving the preventive consciousness can lessen the damages from the rainstorm.
