| Abstract: | By the use of the number of days of rainstorms and maximum daily precipitation observed at 25 stations in the past 45 years, the time-spatial distribution offrequency of rainstorm and maximum daily precipitation are analyzed. It shows that theaverage trend of extreme rainstorm events since the 1980s is that, except north China,the frequency and intensity are obviously increased. The period of rainstorm frequencyis about 10 years. |
