[Objective] The aims of this study are to investigate on the evolution of rainstorm events and the sources of water vapor transport in Hefei under the background of urbanization, and to provide scientific basis for local rainstorm forecast and formulation of adaptive disaster prevention and reduction policies. [Methods] Trend analysis, Mann-Kendall non-stationarity test, GIS spatial interpolation and other methods were used to explore the spatiotemporal evolution of rainstorm events in Hefei, on this basis, the characteristics of rainstorm water vapor transport were analyzed based on the backward trajectory HYSPLIT model of Lagrange method. [Results (1) The urban heat island effect showed an upward trend (0.266°C/10a), impervious water surface continued to increase by 4.99%, the large-scale interannual variability of urban- suburban rainstorms had a feature of asymmetry, with an increase in the amount and number of days of urban rainstorms and a decrease in the intensity of rainstorms at a rate of 1.7 mm/(10 ad); and an increase in the intensity of suburban rainstorms at a rate of 1.1 mm/(10 ad); and a decrease in the amount and number of days of rainstorms. The spatial distribution of the large value area of rainstorm intensity extends outward from urban areas. (2) Urbanization had increased the number and extremity of rainstorm events in downwind urban areas, and the urbanization effect was more pronounced in the rapid development phase than in the slow development phase. The contribution of urbanization effects to the rainfall, number of days and intensity of rainstorms was 41.2%, 50.1%. (3) The water vapor transport from the Indian Ocean. the Bay of Bengal to the South China Sea and the Western Pacific accounted for 44%, 64% and 54% of the total water vapor, respectively, and the water vapor mass from the southwest was the main source of water vapor during the rainstorm process because of its low initial height and large specific humidity. [Conclusion] The asymmetry of rainstorm events in the suburbs of Hefei is more significant in the rapid development stage of urbanization. In the future, we should strengthen the research on the mechanism of rainstorm time change under the background of urbanization. [ABSTRACT FROM AUTHOR]
