| 摘 要： | 对北京城区和郊区的自动气象站的部分小时降水量资料进行了分析和概率分布的拟合，结果为：小时降水量适用对数－Ｗｅｉｂｕｌｌ分布模式拟合；中到大雨时，城市效庆对下风区的短历时降水雨量增加影响最明显；而在市中心，短历时降水暴雨的发生概率和强度增加最显著。

| Abstract: | Hour precipitation from AWS in urban and suburb of Beijing is analysed to study the effects of urbanization on short duration precipitation.Results show that hour precipitation can be fitted to logarithm Weibull distribution and that the enhancement of rainfall due to urbanization is remarkable in downwind under moderate/heavy short duration precipitation process,and that the increase of probability and intensity of torrential rain is significant in urban center. |

| Keywords: | urbanization effect short duration precipitation probability distribution |
