| 摘 要： | 采用天气学及动力学方法,对沿祁连山两次典型的区域性大—暴雨天气从环流背景、中小尺度天气系统、动力机制以及地形特征、增雨过程等方面进行了对比分析,找出了两次过程的相似点与不同之处,结果表明:"东高西低"切变辐合、低空急流及相对稳定的环流形势是沿祁连山区域性强降水产生的关键,特殊的地形地貌及人工增雨作业为增加祁连山区降水量提供了有利条件。 |
| 关 键 词： | 祁连山区 强降水 人工增雨 |

| Abstract: | Using the synoptic meteorology and dynamics methods,the circulation background, mcro-and small-scale weather systems,dynamic mechanisms and orographic features,as well as artificial precipitation stimulation of two typical region heavy-rainstorm weathers along Qilian Mountain were compared and analyzed.It is found that there are similar and different at two rainstorm processes,namely,shear convergence,low-level jet,and relative and stable circulation situation are a key of regional rainstorm occurring along Qilian Mountain,the special orography and geomorphology,artificial precipitation stimulation provided the favorable conditions for increasing precipitation of Qilian Mountain region. |
| Keywords: | Qilian Mountain region Heavy precipitation Artificial precipitation stimulation |
