长江三峡地区宜昌、巴东短历时极值降水特征分析

The Characteristics of Short-duration Precipitation Extremes of Badong and Yichang Stations in the Yangtze Three Gorges Area

摘要: 利用长江三峡库首宜昌站及库区巴东站1955—2008年分钟降水强度资料,采用广义极值分布和线性矩参数估计方法,拟合两站7个短历时(60min以内)年最大降水量概率分布,推断各历时有关重现期降水极值,计算各历时暴雨频次及年最大降水量气

Abstract: Based on the minute precipitation intensity data of Yichang and Badong Stations in the Yangtze River Three Gorges from 1955 to 2008, the generalized extreme value distribution(GEV) and the L-moment method of para
