Using the hourly precipitation data of the automatic ground station from 2008 to 2016 with a resolution of 0.1°×0.1°, integrated with the multisatellite precipitation data from the Climate Prediction Center Morphing (CMORPH), the Meiyu season will be divided into three periods: before Meiyu (from May 1st to the day before the Meiyu starting), during Meiyu (from Meiyu starting to Meiyu ending) and after Meiyu (from the day after Meiyu ending to August 31st). This paper analyses the temporal and spatial characteristics of precipitation during the rainy season in the Dabie Mountains area and concludes that: During the rainy season, the average annual precipitation was 360.3 mm, and the average precipitation before and after the rainy season was 279.9 mm, 287.0 mm, respectively. There were three major precipitation areas in the Meiyu season, distributed in the middle section of the north side of the Dabie Mountains, the southeast side and the southwest side of the central peak. The diurnal precipitation variation during the Meiyu period presented a bimodal characteristic, with the peak time at 9 o’clock and 16 o’clock, respectively. The diurnal variation of precipitation before and after the rainy season showed a single peak. The large occurrence probability of heavy precipitation in spatial distribution also gradually rose with the three periods of before Meiyu, during Meiyu and after Meiyu.
