摘要
呼和浩特市高速发展的城市化进程和气候变化的影响,近年短时暴雨呈上升趋势,特别从2011年开始,呼和浩特市年降雨量显著增大,导致高强度降水频率显著增大,造成城市内涝现象时有发生。从短历时降水强度历年变化、短历时降水极值入选个例、短历时降水强度均值对比、呼和浩特短历时降水≥10 mm雨强次数变化以及短历时最大降水量空间分布5个方面分析了呼和浩特短历时强降水特征变化,并提出了研究的结论。
Influenced by the urbanization and climatic change, the short - time rainstorm in Hohhot has increased in recent years, especially from 2011, the annual rainfall has obviously increased, the strong rainfall frequency has in- creased, and the urban waterlogging has occurred frequently. The change features of strong short - duration precipi- tation in Hohhot have been analyzed from five aspects, such as the change of short - duration precipitation intensity in past years, the selected single example of short - duration precipitation extreme, mean value compare of short - duration precipitation intensity, times change of short- duration precipitations〉 10 mm rainfall intensity in Hohhot, and spatial distribution of the maximum short - duration precipitation. And the research conclusion has been put forward.
