摘　　要：充分认识暴雨的时空分布特征规律,设计出符合当地暴雨时空分布特征的特征降雨过程,可提前预测该类型降雨条件下的洪涝风险,对于构建洪涝灾害防御体系具有重要的意义。基于天津市历史降雨资料,对天津市降雨的时空分布特征进行分析,结果表明,天津市降雨的时空变化特征与下垫面地形及引起降雨的水汽来源相关,时空分布特征复杂多样,分析的降雨时空分布特征清晰,物理机制解释明确,可为洪涝风险管理提供借鉴和参考。It is essential to fully understand the spatiotemporal distribution characteristics of heavy rainfall and design a characteristic rainfall process that aligns with the local rainfall distribution.This approach can allow for the early prediction of flood risk under specific rainfall conditions,which is crucial for building a flood disaster defense system.This study analyzes the spatiotemporal distribution characteristics of rainfall in Tianjin based on historical rainfall data.Results indicate that the spatiotemporal variability of rainfall in Tianjin is related to the underlying surface topography and the moisture sources that trigger rainfall.The distribution characteristics are complex and diverse.The extracted heavy rainfall spatiotemporal distribution features are clear,with well-defined physical mechanisms,providing valuable insights and references for flood risk management.
