Using ERA5 reanalysis data of ECMWF and the ultra-high voltage (UHV) transmission line icing observation system to analyze the meteorological conditions of conductor icing in Guizhou from January 24 to 29, 2018, Results show: The weather conditions for this icing event are that the temperature drops below 0°C, there is weak rainfall, and the humidity is generally between 95% and 100%; the direction is mainly northerly wind, with wind speed of 2~6m/s; the air pressure rises. The meteorological elements that are more relevant to icing are environmental temperature, air pressure, and precipitation. The relationship with wind speed and relative humidity is small.
