选取2003-2013年黄河中游地区16场致洪暴雨过程,将其分为以副热带高压影响为主形成的暴雨过程和以西风带低压槽为主形成的暴雨过程,同时对暴雨过程中的物理量场进行了分析。结果表明:以副热带高压为主形成的暴雨过程物理量指标值明显大于以西风带低压槽为主形成的暴雨过程的;盛夏7-8月的暴雨物理量指标明显大于9月的;暴雨容易出现在物理量场的几个典型区域内,如高能舌区、等值线密集区、闭合高中心附近等。

Sixteen flood-causing rainstorms in the middle Yellow River from 2003 to 2013 were classified into two categories:one was caused direct-ly by the subtropical high and the other was associated with the westerly trough. The physical quantity fields were analyzed. The results show that the physical quantity indexes values of the rainstorm caused directly by the subtropical high are significantly higher than the rainstorm associated with the westerly trough;the physical quantity indexes values of the rainstorm occurred in July to August are significantly higher than that occurred in September;the rainstorms can easily appear in several typical regions of the physical quantity fields,such as the areas of high energy tongue,in-tensive equivalent line,nearly by the closed high values and so on.
