| 摘 要： | 利用卫星云图及柳州Doppler雷达等资料，对2010年6月17—18日发生在桂西北局地性的一次强降雨天气过程进行分析，结果表明：（1）高原有小槽不断东移、超低空西南急流的建立为此次暴雨发生提供了有利的大尺度背景。（2）地面静止锋附近有明显的上升运动区存在，非常有利于中尺度对流的发生发展。（3）高水汽、高对流不稳定能量...

| Abstract: | By using the satellite image, Liuzhou Doppler radar data, the strong rainfall weather happened on June 17-18, 2010 in north-west region of Guangxi is analyzed. The results show：（1） trough process A small moving eastward from plateau and south-west jet establishing in low altitude are both favorable to rainstorm in Large-scale background. （2）The upward motion near stationary front is conducive to the development of mesoscale convection. （3） High -moisture, strong convective instability energy, and weak convective inhibition energy and low uplift index help MCS maintain.（4）On the satellite images, there is TBB 〈-80 ℃ center area during MCS development. The heavy rainfall mainly occurs in the south of this center. |
