摘要
用三参数Weibull分布，甘倍尔分布和对数正态分布对吐鲁番平原，山区一日最大降水量年极值频率分布进行拟合；得出山区一日最大降水量平均为平原的4--6倍，山区一日最大降水量年极值出现时期90％集中在夏季，而平原则占50％。
The conclusion that day maximum precipitation in mountain areas is four to six times as much as in plain while 90% of the annual extreme value in day maximum precipition is in summer and 50% of that in plain is according to the frequency distributing analysis to the annual extreme value on Turpan＇ s day maximum precipitation in plain and mountain areas by using the distrbuting ways of three parameter Weibull, Ganbull and logarithm normality.
