Moreover, the southeastern coastal islands and coastal areas have the most heavy rain days, and the number of rainy days decreases toward the northwest. On average, there is less than one day of heavy rain every year in the northwest plateau. The southeastern or eastward slopes of the Taihang Mountains, Dabie Mountains, Nanling Mountains, and Wuyi Mountains are the centers of heavy rainstorms in these areas.
