Description :
The AA. present the effects of the regional precipitation trend change on the area and intensity of severe acid rain in southern China. The spatio-temporal distribution characteristics of SO2 and NO2 are analysed. The significant increase in summer storm precipitation from 1991 to 1999 mitigated the annual precipitation acidity in the south of the Yangtze River and reduced the area of severe acid rainfall. On the other hand, the decrease in storm rainfall in summer expanded the area of severe acid rainfall in the south of the Yangtze River in 2000-2006. Therefore, the change in seasonal precipitation is an important factor in the severe acid rain regions moving eastward and expanding in southern China.
