How is the freezing rain formed?

Freezing rain is when snowflakes fall from the sky in winter. There is a relatively warm air layer in the middle, such as 2000 to 3000 meters. The intermediate warm layer temperature is about 1-4 degrees. At this temperature, after the snow falls, it becomes water droplets through this air layer, and the water droplets fall further. When it falls near the ground, the near-ground temperature is below zero. At this time, water drops fall on the ground or ground attachments and freeze immediately, but not into ice, but water freezes into a considerable layer of ice sheet, which is called freezing rain. Generally, this freezing rain has a great influence on the wires. When the freezing rain is severe, the diameter of the wire will increase by about two or three centimeters. When wires exceed their load, they will break wires, which will affect the traffic on the ground and make it very difficult for people and vehicles to walk. Freezing rain occurred in most parts of Guizhou Province on the morning of June 5438+1October 8, 2008.
