Abstract: Extreme rainfall storm values are most important for determining design floods of large water resource projects. Based on the storm data in China, some relevant problems of the extreme point rainfall storm values are discussed in this paper, including maximum 24 hr point rainfall, maximum point rainfall for different duration and seasonal variation of extreme values of rainfall storm. Numerous figures and tables of maximum point rainfall storm records are presented here in. In addition, spatial pattern of the rxtreme values and their influencing factors are also discussed.
