后牛顿近似下旋转椭球体的内外度规
Based on rain drop size distribution ( dsd ) data measured in qingdao , guangzhou and xinxiang , the radar reflectivity factor z for spherical rain drops , the radar reflectivity factor zh and differential reflectivity zdr for oblate ellipsoid rain drops have been calculated . the relation of reflectivity and rainfall rate for conventional meteorological radar and the relation of reflectivity , differential reflectivity and rainfall rate for multiparameter radar are regressed , the performance difference of two kinds of radar for measuring rainfall and difference for measuring rainfall in different regions are also discussed
基于我国青岛、广州和新乡地区雨滴尺寸分布数据，计算了球形雨滴雷达反射因子，椭球形雨滴雷达水平极化反射因子和差分反射率，回归给出了这些地区的常规气象雷达反射因子与降雨率的经验关系和多参数雷达水下极化雷达反射因子、差分反射率和降雨率关系，并对其测雨精度和地区差异进行了比较。
