Mapping the Distribution of Summer Precipitation Types over China Based on Radar Observations

In this study, the spatiotemporal distribution and characteristics of different precipitation types (stratiform, convective, snow) over China are analyzed using radar mosaic images during summer season 4 years (from 2018 to 2021). The convective occurs most frequently along eastern coast regions. June, strong convection center is located in Southern moves northward Eastern July, while lowest frequency August. Stratiform dominates mainly distributes inland regions, with highest Snowfall primarily presents mountains plateau regions Western occurrence around 20%. snowfall area July significantly smaller than that June stratiform, show diurnal variation terms solar standard time (LST) especially for snowfall. demonstrates a bimodal pattern, peak afternoon (15–16 LST) secondary early morning (04–07 LST). active from next (14–05 more common nighttime (around 12%) daytime 4%). ratio at midnight higher It expected study on can be used as reference hydrometeorological research also improve understanding China.
