| 摘 要： | 利用ＭＭ４中尺度模式，模拟了１９９６年８月发生在太行山南段的一次特大暴雨过程。采用对比试验的方法，先后研究了减弱低空急流和减弱高空急流后，降水及物理量的变化。数值试验结果表明，低空急流和高空急流对本次暴雨过程的形成与维持均有促进作用；相比之下，低空急流对暴雨的影响更为显著。

| Abstract: | By means of MM4 model,the process of torrential rain over the southern Haihe River Basin during August 1996 was simulated.Through compared tests,the changes of precipitation and elements were studied after low and high level jets were weakened.The results demonstrate that the jets are favorable to the torrential rain occurrence and maintenance,the low level jet has more important effects on the rain compared with that of the high level jet. |

| Keywords: | torrential rain low level jet high level jet numerical simulation experiments |
