@@@@Based on daily precipitation data and operational synoptic chart, important heavy rain processes in China from April to October in 2012 were selected by comparing with the 30 a mean precipitation from 1981 to 2010, and a brief introduction on the synoptic system, rainfall occurrence time, rainfall area and accumulative amount of precipitation of these processes is presented. The statistical results indicate that there were 190 heavy-rain-days and 34 important heavy rain processes in China from April to October in 2012. Single station daily maximum precipitation is 487 mm and the process maximum rainfall is 631 mm. The rainstorm processes are more than average year in the South China and the regions south of the Yangtze River in April. Heavy rain in mid-late of July occurred frequently in the Yangtze River basin and caused the largest flood peak of the Yangtze River Three Gorges since being built.
