Abstract: Using daily precipitation observations from Chinese weather stations, the processes of summer torrential rains from 1951 to 2010 in North China are analyzed. In accordance with the location, intensity and movement of rainstorms in Taihang Mountains, the summer torrential rains in North China are divided into five types: rainstorm to the east of Taihang, rainstorm to the west of Taihang, rainstorm over Taihang, rainstorm on both sides of Taihang, and rainstorm weakening when crossing Taihang. The analysis shows that the “rainstorm to the east of Taihang” occurs most frequently. Weather system patterns differ in their rainstorm types.
