摘要：

为了加强对武汉市主汛期降水气候和气候变化特征的了解,使用统计方法分析武汉市1955—2015年汛期小时降水数据。结果表明：武汉主汛期降水量443.5 mm,降水小时149 h,降水日数22.7天,降水强度19.5 mm/d;主汛期降水量05时最多28.9 mm,降水发生概率最大是04时13.1%,最小21时8.3%;主汛期内小时降水强度05时最大3.6 mm/h,16时最小1.9 mm/h;降水量、降水强度呈上升趋势,主汛期第3旬的降水强度增加趋势明显。城市防汛抗内涝应更多关注小时降水变化。

Abstract:

The paper aims to strengthen the analysis of the precipitation characteristics and climate change during the main flood season in Wuhan. We analyzed the hourly precipitation data of Wuhan from 1955 to 2015 by using statistical methods. The results showed that: the precipitation of main flood season in Wuhan was 443.5 mm, the precipitation hours were 149 h, the precipitation days were 22.7 days, and the precipitation intensity was 19.5 mm/d; the maximum precipitation during the main flood season was 28.9 mm at 05:00, the precipitation occurrence probability was the maximum (13.1%) at 04:00, and the minimum (8.3%) at 21:00; the hourly precipitation intensity during the main flood season was the maximum (3.6 mm/h) at 05:00, and the minimum (1.9 mm/h) at 16:00; the precipitation and precipitation intensity were on the rise, and the precipitation intensity in the 3 rd ten days during the main flood season was increasing obviously. Urban flood control and anti-waterlogging should pay more attention to hourly precipitation changes.
