摘　　要：为探究连云港地区典型暴雨洪水特征,根据1956~2018年实测降雨资料,通过对降雨级别、造成洪涝灾害等因素进行综合考虑,选取连云港地区8场典型年份典型暴雨,并对历史暴雨天气系统、时空分布特征及对应的洪水洪量组成和重现期进行统计分析。结果表明:连云港地区典型暴雨受季节性影响明显,极端天气有增多趋势,典型暴雨降雨量区间较为集中。To explore the characteristics of typical rainstorm and flood in Lianyungang area,based on the observed rainfall data from 1956 to 2018,eight typical torrential rain events in Lianyungang were selected by considering the factors such as rainfall level,flood and waterlogging disaster,the historical rainstorm weather system,the temporal and spatial distribution characteristics and the corresponding flood composition and recurrence period were statistically analyzed.The results showed that the typical rainstorm in Lianyungang area was obviously influenced by the seasons and the extreme weather tended to increase,the typical rainstorm was concentrated and different rainfall caused different rainfall processes.
