| 摘 要： | 本文根据大量不同类型降雨的雨滴谱资料，分析了两种雷达测雨与滴尺度分布的关系，模拟计算了双线偏振雷达可测到的(R/ZH)-ZDR和常规天气雷达可测到的Z-R经验关系和它们在测量降雨率精度的对比分析。表明差分反射率ZDR对改进雷达测雨的精度有着明显的优势。

| Abstract: | In this paper,by using the large amounts of raindrop size distribution data of various type rainfall,the relation between rainfall measurements of two kinds of radar and drop size distribution has been analysed.By simulation calculations of the formula of R/ZH-ZDR dual linear polarization radar and Z-R the cenventional weather radar, we have compared their measuring accuracy of rainfall rate.The results show that the differential reflectivity ZDR is sensitive to variation of raindrop size distribution.This is useful to improve the accuracy of rainfall measurements by radar. |

| Keywords: | dual linear polarization radar differential reflectivity accuracy of rainfall rate measurements |
