The hourly precipitation data sets with a spatial resolution of 01°×01°, which is the integrated CMORPH (Climate Prediction Center Morphing) rainfall products, are used to analyze the temporal and spatial distribution of precipitation in the Dabie Mountain region from 2012 to 2014 The average of annual precipitation was 9785 mm over the Dabie Mountain region, and the heavy rain center was located at the southeast of the Dabie Mountain peak. The main rainfall season was from May to July, with obvious topographic character. There is a single peak in the time series of monthly rainfall, and the monthly average precipitation is the most in July in 12 months. As to the spatial distribution, Dabie Mountain and the area to the East had the more rainfall. The heavy rain and storm rainfall occurred more frequently in these regions, and in the central peak area and the eastern part, there were most heavy rain days, increasing with altitude. The location of the precipitation center moved with seasons. In winter, the precipitation center was located at the southeastern part of the peak, and in spring it moved northwestward and was located at the north of the main peak. From September, the center came back to the south of the main peak. It is concluded that the evolvement of atmospheric circulation and the interaction with terrain were the main causes for the orographic precipitation (precipitation increasing with the elevation) and seasonal variation.
