摘要
本文根据我国青岛、广州和新乡地区实测雨滴尺寸分布数据 ,计算了球形雨滴雷达反射因子Z ,椭球形雨滴雷达反射因子ZH 和差分反射率ZDR,回归给出了这些地区的常规气象雷达测雨算式Z～R关系和多参数雷达测雨算式ZH、ZDR～R关系 ,并对其测雨精度和地区差异进行了比较 .
Based on raindrop size distribution (DSD) data measured in Qingdao,Guangzhou and Xinxiang,the radar reflectivity factor Z for spherical raindrops,the radar reflectivity factor Z H and diferential reflectivity Z DR for oblate ellipsoid raindrops are calculated.The reflectivity rainfall relation (Z R relation) for conventional meteorological radar and reflectivity,differential reflectivity rainfall relation for multiparameter radar (Z H,Z DR R relation) are given by regression,and the performance difference of two kinds of radar for measuring rainfall and difference for measuring rainfall in different regions are also discussed in the paper.
