Abstract The definition of rainstorm process is introduced,and the rainstorm process is classified by using hourly precipitation data of Hubei meteorological observatory in flood season (April-September) from 2008 to 2017.At the same time,the spatial distribution and diurnal variation characteristics of frequency,process precipitation,short-term heavy rainfall and extreme heavy rainfall characteristics of 90 rainstorm processes in southwestern Hubei are statistically analyzed in detail.The analysis results are expected to further reveal the regularity of heavy rainfall in southwest Hubei,and providing reference for the forecast and early warning of rainstorm in southwest Hubei.
