摘　　要：文章基于五老峰观冰站2020年1月一次覆冰过程的覆冰数据,以及同时期的天气数据和再分析数据,对导线覆冰变化和同期天气状况进行分析,主要结论如下:①本次覆冰过程中,东西向和南北向导线覆冰重量最大值分别为230 g和197 g;②覆冰期间,温度经历了3次“V”形变化,覆冰增长在大幅度降温后;③北风造成了东西向导线的覆冰重量大于南北向导线,这说明覆冰设计时风向考虑的重要性;④导线覆冰重量与空气比湿的相关性较大,而与导线温度的相关性则较小。Based on the icing data of an icing process at wulaofeng lce Station in January 2020,as well as the weather data and reanalysis data of the same period,this article analyzes the changes in wire icing,weather conditions and air trajectories.the following are as follows:①in this icing process,the maximum ice weight of east-west and north-south wires is 230 g and 197 g respectively;②during the icing period,the temperature experienced three“V”-shaped changes,and the icing growth usually occurred after a substantial cooling;③the northerly wind causes the weight of the icing on the east-west guide line to be greater than that of the north-south guide line,which illustrates the importance of wind direction consideration in icing design;④the icing weight of the wire has a greater correlation with the specific humidity of the air block,while the correlation with the wire temperature is relatively small.
