摘要
多普勒天气雷达是监测暴雨等灾害性天气的重要手段。文中将郑州雷达站某次降雨的雷达1小时累积雨量(OHP)产品资料通过网格插值法处理成内涝数学模型所需的降雨数据,再将其带入内涝系统中,进行郑州市区内涝积水的模拟。同时,通过调整网格插值法中的相应参数使模型的计算值与实测值之间的误差不断减小,以更接近实际情况。结果分析表明,网格间距d和搜索半径R都较小时,计算值较接近于实测值。
Doppler radar is an important tool for monitoring the storm and other severe weather. In this paper, 1-Hour Precipitation Accumulation products of a single rainfall in Zhengzhou radar station is processed by grid interpolation into a rainfall data the waterlogging mathematical models is needed to, and then the rainfall data is brought into waterlogging system to simulate Zhengzhou city waterlogging water accumulation. At the same time, it adjusts the corresponding parameters in grid interpolation to make the error between the calculated and measured values decreasing, to be closer to the actual situation. The results show that when the grid spacing d and search radius R are small, the calculated value is closer to the measured values.
