摘　　要：文章利用2020-03-22—2020-03-27北京延庆海陀山的能见度观测数据对比分析延庆站、佛爷顶站能见度的变化特征,选取期间的降雪天气过程,分析能见度变化与气温、气压、相对湿度、风速、降水量变化的关系。研究结果发现,前向散射式能见度仪在海陀山地区应用较好,能够监测到降雪天气过程时能见度的变化特征。Based on the visibility observation data from March 22,2020 to March 27,2020 at Haitao Mountain in Yanqing of Beijing,this paper makes a comparative analysis of the variation characteristics of visibility at Yanqing station and Foyeding station.The snowfall weather process is selected to analyze the relationship among visibility change and temperature,pressure,relative humidity,wind speed and precipitation change.The results show that the forward scattering visibility meter is well applied in Haituo Mountain area,and which can monitor the variation characteristics of visibility during snow weather process.
