| 摘 要： | 对2005年8月20日和2006年6月13日发生在桂西的两次强降雨并伴有强对流天气过程的影响系统、物理量场和FY-2C红外云图及雷达回波特征进行对比分析。结果表明：造成桂西两次强降雨都是在充足的水汽条件和强烈的上升运动条件下发生的；主要影响系统来自低层切变线、高空低槽和地面静止锋；强降雨过程发生在强烈的不稳定层结区域和K指数高值区。

| Abstract: | This paper conducts the comparison analysis of the influence system, the physical quantity field and the FY-2C infrared cloud chart and the rador echo characteristic of the two strong rainfall with the strong convection weather processes occurred on June 13, 2006 and August 20, 2005 in the west of Guangxi. The resalt indicates that the strong rainfalls occur in the conditions of the sufficient water vapor and the intensive lifting movement. The major systems come from the shear line of low-layer, the low trough of upper air and the ground stationary front. The strong rainfall processes occur in the intensive unstable level-knot zone and the high value zone of K index. |
