长潭水库最大暴雨及短时暴雨计算分析

以长潭水库流域的历史暴雨作为研究对象，运用数理统计方法，分析了长潭水库库内宁溪、白石等雨量站及临海等周边雨量或者气象站的日降雨记录资料短时降雨资料，建立了长潭水库设计暴雨时程分配雨型和设计暴雨面分布雨型．认为该水库最大暴雨和短时暴雨的推求，应充分考虑库区面雨量的权重和雨形成的气象特征，针对性地确定不同的站点，从而求出短历时的可能最大暴雨．从而为更好地比较和分析可能最大暴雨成果提供基础依据．

Computational Analysis Short Time Storm on Maximum Downpour and in Changtan Reservoir

Based on historical rainstorm data of Changtan Reservoir watershed, the daily rainfall records and the short-time rainfall data of nearby rainfall stations or meteorological stations, such as Ningxi, Baishi and Linhai is analyzed by mathe- matical statistics method, and the design storm distribution pattern and design storm coverage pattern in Changtan Reservoir area are set up. The computation analysis takes several factors into consideration, including maximum torrential rain, short time storm, hyetal weight in reservoir area and weather characteristics, in order to predict the maximum rainfall in short time in different sites, which provides theoretical basis for the analysis on maximum torrential rain.
