Freezing rain is rain maintained at temperatures below freezing by the ambient air mass that causes freezing on contact with surfaces. Unlike a mixture of rain and snow or ice pellets, freezing rain is made entirely of liquid droplets. The raindrops become supercooled while passing through a sub-freezing layer of air hundreds of meters above the ground, and then freeze upon impact with any surface the… WebFeb 9, 2024 · However, according to a statistical survey of freezing rain observations in China from 2000 to 2024, we find that there were 656 events that occurred at Tas …
