【摘要】 天津是一个干旱且极易发生暴雨内涝的直辖市。通过介绍与暴雨关系密切的天津市概况,选用天津市境内及其周边66个雨量站的观测资料,在统计计算10min、30min、60min、3h、6h、12h、24h、3d和7d这9个时段的年最大暴雨量均值和极值的基础上,研究了9个时段年最大暴雨量均值和极值在天津市境内的空间分布规律。对于认识天津市暴雨特性,指导暴雨观测和防灾减灾具有重要意思。更多还原

【Abstract】 Droughts and rainstorms occur frequently in Tianjin Municipality. The general conditions closely related to the occurrence of rainstorms in Tianjin were introduced. The statistical data of the average annual maximum rainstorm and the extreme annual maximum rainstorm in 10 minutes、30 minutes、60 minutes、3 hours、6 hours、12 hours、24 hours、3 days and 7 days were obtained. The spatial distribution of the 2 main parameters in these 9 durations was researched, which was useful to understand rainstorm characteristics of Tianjin as well as to instruct rainstorm observation. Therefore, it is of significance for preventing and controlling flood disasters and reducing the flood-caused losses to research the spatial distribution of the rainstorms.更多还原
