雷达定量估测降水技术在三峡流域面雨量估算中的应用

利用完全覆盖三峡流域的3部多普勒天气雷达探测资料，并结合三峡流域周边水文自动站实时观测资料，集成多种定量降水估算方法，对三峡流域进行面雨量估算。结果表明：这种方法在一定程度上弥补了传统利用自动站观测资料采用插值方法计算流域面雨量中由于自动站观测资料时空分辨率不足的缺点，提高了流域面雨量的估算精度，从而更好的为三峡水资源利用和洪峰预报提供重要参考

RADAR QUANTITATIVE ESTIMATION OF PRECIPITATION TECHNOLOGY APPLICATION ON THE AREA RAINFALL CALCULATION OF THREE GORGES VALLEY

Using three doppler radars which cover the three gorges valley and the real-time observation data with rain gauge in the three gorges surrounding valley,the rainfall in the three gorges valley area was estimated by integrating many quantitative estimations of precipitation technology.The results show that this method make up for the defect of the space and time resolution of automatic station observation data by using traditional automatic station observation data with interpolation method to calculate the river Valley in the area rainfall.And this method is better to providing important reference to the three gorges water exploitation and flood peak forecast.
