摘要
基于中国台站逐日降水观测资料,对华北地区1951—2010年夏季暴雨过程进行了分析,根据太行山脉地形特征及暴雨落区、强度及移动等特征,结合暴雨天气预报经验,对太行山影响下华北地区夏季暴雨进行了分型,将华北暴雨分为太行山以东暴雨型、太行山以西暴雨型、太行山区暴雨型、太行山两侧暴雨型和过山时减弱暴雨型五种型态,挑选和确定了各种分型暴雨的典型个例库。分析表明太行山以东暴雨型出现概率最高,不同型态暴雨的主要影响天气系统也各不相同。
Using daily precipitation observations from Chinese weather stations, the processes of summer torrential rains from 1951 to 2010 in North China are analyzed. In accordance with the location, intensity and movement of rainstorms in Taihang Mountains, the summer torrential rains in North China are divided into ifve types：rainstorm to the east of Taihang, rainstorm to the west of Taihang, rainstorm over Taihang, rainstorm on both sides of Taihang, and rainstorm weakening when crossing Taihang. The analysis shows that the“rainstorm to the east of Taihang”occurs most frequently. Weather system patterns differ in their rainstorm types.
