| 摘 要： | 通过对2012年夏季一次局地暴雨天气过程发生时的主要天气形势、影响系统、各物理量场特征、卫星云图和雷达回波的演变等综合分析,得出贝加尔湖冷涡东移加深且移动缓慢是此次局地暴雨的关键;低空急流的存在,对降水量有增幅作用;由于大兴安岭地形阻挡造成迎风坡水汽辐合造成暴雨天气。

| Abstract: | By means of comprehensive analysis of the main weather situation, effecting system, physical fields quantity, satellite cloud image and radar echo evolution of rainstorm weather process in the summer of 2012, it concluded that the key to local heavy rain was eastward shift and deep and slow moving of Lake Baikal cold vortex;The existence of low level jet stream was the role of increasing precipitation; the windward slope water vapor convergence caused rainstorm weather because of the Greater Khingan Range terrain blocking. |
