Based on the 2011-2020 Shiqian national weather station and the villages and towns automatic weather stations rainfall data,the characteristics of the rainstorm weather in Shiqian in nearly last 10 years are analyzed,and "three response thresholds" are studied by combining the rainstorm disaster information.The results show that the average annual number of rainstorm days in Shiqian County was 11.4 days, and the average annual number of rainstorm stations was 51.5, mainly from May to September. The monthly rainstorm days peak appeared in May, and the monthly rainstorm stations peak appeared in June. Short-time heavy rainfall was easy to occur from 5 to 7 o’clock. The number of days with heavy rain and short-time heavy rain is unevenly distributed in time and space. The eastern part is significantly more frequent than the western part, and the maximum daily precipitation and rain intensity are roughly the same, mainly in County seat, Fengxiang, Huaqiao and Baisha. When the rainfall in county areas reaches 35mm in one hour or 70mm in three hours or 90mm in six hours,and the rainfall still continue,that will probably become a rainstorm disaster,the weather warning and forecast service should come in time,and it could provide some reference for the future meteorological services in Shiqian county.
