Abstract
The ratio of the skewness coefficient to the variation coefficient is computed with uniform method for the rainfall data from 5 100-13 600 stations with durations of 10-min-3-day and 210 stations with durations of 1-day-90-day and 1-year.The ratio of skewness to variation (Rsv) characteristics of the Pearson type Ⅲ frequency distribution are approached; the regional distribution of Rsv and the Rsv-duration relation are analyzed,and the same affected factors on Rsv are studied.On the condition of the data at present,the single Rsv value of 3.5 is not suitable for each region and each duration in rainstorm frequency analyses.
