Abstract: Based on the daily precipitation data monitored by the national surface meteorological observation station of Hubei province in spring and autumn from 1961 to 2017, the characteristics and effects of continuous rain disasters in Hubei province are analyzed, so as to reduce the impact on production and life. The results show that the occurrence frequency of continuous rain in spring in Hubei province is higher in the south than in the north while in autumn is more in the west than in the east,and more in the south than in the north,most in the southwest of Hubei. Since entering the 21st century, the occurrence area and degree have reduced in spring, but since 2010, the occurrence scope and degree show an increasing trend in autumn; The convergence of cold and warm air in Hubei province is the main cause of continuous rain; Continuous rain not only causes heavy losses to agricultural production, but also causes harm to relevant production activities in the storage and transportation industry, and also affects people's physical and mental health, so corresponding defensive measures should be taken.
