摘　　要：利用2021年5—10月六盘山站观测的分钟雨滴谱数据,结合六盘山自动气象站观测资料,选择46次降水过程,对六盘山气象站降水的雨滴谱分布、物理特征及雷达反射率因子Z和降水强度R的关系进行分析研究,拟合得到适用于六盘山站降水过程的Z-R关系。结果表明:Z=175R1.6关系式可以较好地描述六盘山站降水情况,降水强度随着雷达反射率因子增大而增大;当降水强度增大时,估测降水量的误差会随之偏大。利用Z=175R1.6估算的六盘山站的降水量接近自动气象站实测降水量,二者相关性较高。Based on the minute raindrop spectrum data observed at Liupanshan station from May to October 2021 and combined with the observation data of Liupanshan automatic weather station,46 precipitation processes were selected to analyze and study the relationship between raindrop spectrum distribution,physical characteristics,radar reflectivity factor Z and precipitation intensity R of the precipitation at Liupanshan weather station,and the Z-R relationship suitable for the precipitation process at Liupanshan station was fitted.The results show that the Z=175R1.6 equation can describe the precipitation of Liupanshan station well,and the precipitation intensity increases with the increase of radar reflectance factor.When the precipitation intensity increases,the error of precipitation estimation will become larger.The precipitation of Liupanshan station estimated by Z=175R1.6 is close to the measured precipitation of automatic weather station,and the correlation between the two is high.
