After September, the winter wind was established and the rain belt retreated south. Affected by the summer monsoon, the number of rainstorm days and rainfall distribution in China decrease from southeast to northwest inland, with mountains more than plains. Moreover, the southeast coastal islands and coastal areas have the largest number of rainstorm days, and the farther northwest, the less. In the northwest plateau, there is less than one day of heavy rain on average every year. Mountain slopes in the southeast or east, such as Taihang Mountain, Dabie Mountain, Nanling Mountain and Wuyishan Mountain, are the centers of rainstorm days in these areas.
