Using the radar data of CINRAD/CD in Guiyang, Guizhou Province, in the period from May to August in 2014-2016, the spatial and temporal distribution characteristics of convective precipitation in Guiyang area were analyzed. First, 551 cases of convective precipitation echoes were selected, and then the echoes were statistically analyzed from six aspects of morphological characteristics, occurrence frequency, location, diurnal variation, duration and large-scale background conditions. The results showed that the convective precipitation echoes can be classified into cell type, linear and regional type, of which the linear type is about 50%, being the most common form of convection organization in Guiyang area. Compared to the linear and regional types, the convective duration of cell type is the shortest and has obviously local characteristics. More than 70% of convective precipitation events occur under the southwest vortex or southwest airflow weather condition. Convective precipitation often occurs in the southwest and southeast of Guiyang and rarely in the north. Convective initiation time has two peaks in the afternoon and around midnight, respectively. Finally, three representative convective precipitation events were carefully examined in terms of lifetime, coverage and intensity of precipitation.
