| Abstract: | Gansu province is located at northwestern interior of China, and most areas belong to arid region with less rainfall, but rainstorm events always occurred with short duration and big intensity characteristics. Moreover the short duration rainstorm created the record in the world events. The rainstorm characteristics and the patterns of time and space distribution are analysed with emphasis.Measured and investigated maximum feature values of rainstorms point over the years are listed, short duration rainstorm regression curves with altitude changes are drawn, and the function of outer and include line of maximum points rainstorm in the Gansu province is selected in the paper. The paper makes the preliminary inquisition of the rainstorm parameter values of mean,extreme, Cv, Cs over the years and the duration distribution and interrelated lines of areas with time change at the typical rainstorms etc. |
