摘要
该文利用自动站降水资料统计出金沙县近10 a的两次极端暴雨天气过程(2007年7月30日和2015年8月18日)。利用常规实况观测资料和NCEP/NCAR每6 h一次再分析全球格点资料(水平分辨率1°×1°)对金沙县出现的两次极端暴雨天气过程进行对比分析,发现两次暴雨过程的区别如下:主要影响系统不同,水汽的主要源地不同,水汽辐合的集中抬升高度不同,物理量垂直分布特征不同。
The precipitation statistics data was used to study the two extreme rainstorms of Jinsha County in re- cent ten years - 730 and 818, and conventional observational data and NCEP/NCAR 6 h reanalysis data（ horizontal resolution of 1°×1°） were used to make a comparative analysis of two major rainstorms in Jinsha County. It is found that two procedures have different major storm affecting system, the main source of water vapor is different, the focus lifting height of moisture convergence is different, the Vertical distribution of physical quantities is differ- ent.
