Using the data observed by the new generation Doppler weather radar in 4 years, the moving characteristics of radar echo are analyzed. It is found that: (1) the echo moving speeds are between 10.0 km·h-1 to 95.0 km·h-1, and the peak value is 45.0-50.0 km·h-1. The echo moving speeds are different in different months. The radar echoes have larger movement speed in late spring (May) and early autumn (September). The echo moving directions are between 120° to 360°, of which 80.6% concentrates betweem 210°-315°, and the moving directions mainly point to southwest, west and northwest; (2) The echo motion characteristics in the precipitation process can be summarized as four types: simple linear type, composite linear type, complex moving type and other types. The proportions of these types are 69.6%, 19.4%, 25.2% and 4.7% respectively. These studies can provide references for the scheme design of weather modification and nowcasting services.
