中文摘要: 利用天气雷达定量测量降水,最常用的是雷达反射因子法。通过计算宁夏平原7个站1983年6—9月的4618份地面雨滴谱资料,给出了该地区不同雨型间的Z-I关系,并对在该地区使用这些关系定量测量降水的结果进行了检验,平均相对误差在30%左右。

Abstract:It is the most common method to use radar reflectivity factor in quantitatively measuring rainfall amount. Based on the calculations of data of 4618 ground raindrop spectra collected from 7 observation stations over Ningxia plain during June to September in 1983, Z-I relationships in different types of rain in this region have been obtained.In addition, the effect of quantitative measuerment of precipitation with these relationships in this region is tested, and the mean relative error is about 30%.
