Using the raindrop spectrum observation data from Chongzuo National Meteorological Observatory and Fangcheng National Reference Climate Station, combined with the rainfall data and radar observation data, we analyzed the structural characteristics and differences of raindrop spectrum at different precipitation stages on the inland leeward side (LSI) and near-coast windward side (WSC) during the impact of typhoon Wipha from August 2 to 3, 2019. The results show that the rainfall of typhoon Wipha is mainly contributed by medium and small raindrops; especially the contribution of medium raindrops is stable above 70%. The rainfall at LSI is dominated by stratiform clouds with relatively gentle rain intensity, while the rainfall at WSC is characterized by mixed cumulus clouds with large rain intensity and severe fluctuations. Due to the strong convective activity and upward motion, the raindrop number concentration and raindrop diameter at WSC are significantly larger than those at LSI. The main factor for the increase of rain intensity at LSI after typhoon landfall is the increase of raindrop diameter, while the increase of rain intensity at WSC after the change from typhoon eye wall to strong convective spiral rain band is mainly due to the increase of raindrop number concentration. The average mass-weighted mean diameter of the convective precipitation of typhoon Wipha is 1.85 mm and the average logarithmic normalized intercept is 3.95 mm-1·m-3. The convective precipitation at LSI is located in the maritime convective region, while at WSC it is between maritime and continental convection.
