摘要
雷达测雨的误差以及水文模型自身的结构和尺度问题等的复杂性,导致了水文预报的精度不理想.这在一定程度上阻碍了雷达测雨技术在水文学中的应用.文中在回顾雷达测雨技术在水文学中已发挥的重要作用的同时,着重对预报精度影响较大的若干因素进行探讨和分析,并就将来雷达测雨技术更好地应用于水文学的研究提出几点建议.
The errors of radar rainfall measurement and the complexity of hydrological model have led to lowed accuracy for hydrological prediction. This hinders the application of radar rainfall data to hydrology. This paper reviews the importance of applying the radar rainfall measurement to hydrology, analyses the key influence on the results of hydrological prediction and puts forward some proposals to improve its application to hydrology.
