摘要
本文利用2000~2015年大埔县79次暴雨天气过程资料,对大埔县暴雨分布规律和影响因素进行了统计分析,结果表明:大埔县暴雨日分布具有明显的季节性峰值特征,一年中四季各月均有暴雨天气出现,3月开始增多,频发于4至8月,9月后逐渐减少;暴雨天气过程中温度、气压具有明显的相关特征;造成暴雨的主要天气系统包括高空低槽、中低层切变、低涡、西南急流、热带气旋或台风以及地面冷锋等。
Rainstorm is one of the major meteorological disasters in Dabu County. It is also one of the most serious and most frequent disasters in the meteorological disasters in Dabu County. It often causes floods and serious soil erosion, leading to engineering accidents, embankment and flooding of crops, resulting in casualties and significant economic losses. With the continuous social and economic development of Dabu County, the economic losses caused by heavy rainstorms are increasing, especially the heavy rainstorms caused by continuous rainstorms and tropical cyclones in flood season. Based on the data of 79 rainstorms in Dabu County from 2000 to 2015, this paper Statistical Analysis the distribution law and influencing factors of rainstorms in Dabu County. The results show that the distribution of rainstorms in Dabu County has obvious seasonal peak characteristics. Rainstorms appear in each month, begin to increase in March, frequently appear in April to August, gradually reduce after September; Rainstorms have obvious characteristics with the temperature and air pressure; the main weather system that causes rainstorms including upper level trough, low~level shear, low vortex, southwest jet, tropical cyclone or typhoon and ground cold front etc.
