This study aims to investigate the characteristics of severe precipitation and its associated disasters in Dafang County to enhance the capability of forecasting local severe weather and provide references for strategy-making of local flood control and geological disaster prevention. Utilizing daily precipitation data and disaster information from the Dafang County National Meteorological Observatory and township automatic weather stations in 2013-2022, we analyze the spatial and temporal distribution characteristics of rainstorms in Dafang County over the past decade and the disaster-causing characteristics of torrential rainfall and heavy rainstorms in each township based on the county's terrain and river distribution. The results indicate that Dafang County has 14.8 days of torrential rainfall and 3 days of heavy rainstorm annually on average, and the trend is on the rise. Torrential rainfall and heavy rainstorms primarily occur from May to September, both showing the distribution of a unimodal pattern. The peak of torrential rainfall often appears in June, and that of heavy rainstorms is in July. The earliest onset of torrential rain is recorded on April 18th, and the latest end of torrential rain is on October 5th. In summary, torrential rain and heavy rainstorms in Dafang County mainly occur in the southern, western, and northern townships, but less in the central region. Their distributions are well correlated with the terrain and water bodies. The townships located on windward slopes or near water bodies are prone to experience torrential rains more frequently than other villages and towns. In terms of heavy rain disasters, the most disastrous severe precipitation always appears in June and July, coinciding with the monthly distribution of torrential rain and heavy rainstorm days. The frequency of disaster caused by torrential rains in townships varies mostly between 10% and 30%, without significant distribution pattern. However, the frequency of disaster caused by heavy rainstorms is higher, particularly in townships in the southern and northern parts with significant altitude differences or located in valley areas, where the disaster rate exceeds 50%.
