自动站点雨量数据到格点化雨量数据的插值方法一直在气象业务中有着重要应用，但传统插值法一般只考虑距离对估测点的影响，不能够真实地反应降水的落区分布。利用多普勒雷达资料对雨量插值结果进行校正，可使得插值后的结果较好地反映雷达反射率分布特征，也可以较好地克服反距离加权插值法的尖点问题。经过业务测试检验，基于雷达校正的雨量插值方法效果较为稳定，可以在业务中进行应用。

Precipitation interpolation algorithm plays an important role in meteorological business,which can gener?ate area rainfall data from point rainfall data. Yet traditional interpolation method only considers the impact of dis?tance on the estimated point data, thus cannot fully reflect the real drop?zone distribution of precipitation. The Doppler radar data are employed to improve rainfall interpolation results,which enables the interpolation results to better reflect the distribution characteristics of radar reflectivity,and to overcome the problem of sharp point in in?verse distance weighting interpolation.Meteorological test results show that this method is reliable in precipitation in?terpolation and stable in calibration effect,thus can be applied in meteorological business.
