| 摘 要： | 对湖北省200次山洪灾害个例逐时雨量及15次逐时水位、流量分析表明:山洪灾害雨量分布可归纳为单峰、双峰、多峰3种类型,其中单峰型所占比例较大;天气系统特征均表现有中尺度系统活动,单峰型主要以局地性降雨过程为主,强降雨历时短,双峰型主要以系统性降水过程为主,强降雨历时较长,多峰型主要以持续性降雨过程为主,强降雨历时长;激发山洪灾害的关键因素主要是6 h以内的雨强。

| Abstract: | Based on the analysis of hourly rainfall in 200 mountain torrent disaster cases and the water-levels and runoff of 15 examples,it is found that the rainfall distributions in mountain torrent disasters generally can be divided into three kinds: mono-apex,bi-apex and multi-apex.The majority were the mono-apex.Mesoscale system activities are found in all of the cases.In mono-apex cases,rains are mostly local,and the heavy rains are transitory.While in bi-apex examples,rains are mainly systematic,and the heavy rain lasts for a longer time.In multi-apex cases,rains are durative,and heavy rains goes on for a long time.The key factor that triggers mountain torrents is the 6-hour rainfall intensity in most cases. |
