| 摘 要： | 为了满足城市暴雨内涝模型对面雨量精细化的需求，在天津城市暴雨内涝模型的基础上，将雷达估算降水产品应用到模型面雨量计算中，针对2012年7月25—26日天津的大暴雨过程，考察4种雷达估算降水产品和两种插值方法计算的内涝模型面雨量。经过对比发现，利用变分方法计算的雷达估算降水产品VAR用曲面插值方法计算内涝模型的面雨量整体效果最好。

| Abstract: | In order to meet the requirements of refinement rainfall prediction in the urban rainstorm waterlogging model. Based on the urban rainstorm waterlogging model of Tianjin, the products of quantitative estimation using jointly radar and rain gauges are used in area rainfall calculation of the urban torrential rain waterlogging model. Based on four products of quantitative estimation using radar and two interpolation methods, a test of rainfall calculation in the urban torrential rain waterlogging model based on the torrential rain process in Tianjin on 25 and 26 July 2012 is performed. The comparison indicates that the variational method is the best in the quantitative estimation of precipitation using jointly radar and rain gauges in combination with a curved surface interpolation method to calculate the area rainfall. |
