摘　　要：通过对贵阳多普勒雷达和独山TWR01小天气雷达资料在一次强降水天气过程中四个时段的观测资料和四个时段的自记降水资料进行分析对比,得出新一代多普勒天气雷达由于贵州地形影响等原因,存在一定的探测盲区,而TWR01小雷达对小范围的对流云层观测更清楚、更接近当时天空的实际情况,是多普勒天气雷达很好的补充。Basing Doppler radar of Guiyang City and TWR01weather radar data of Dushan County, four times observations recorded rainfall data and Self-recording precipitation data during a heavy precipitation process were comparative analyzed. The results show that there is a certain blind spot detection of the new generation Doppler weather radar caused by Guizhou topography. The TWR01 radar observes the small-scale convective clouds more clearly, more closer to the actual situation, which is a good complement to Doppler weather radar.
