Whether the freezing rain is formed because the warm front is strong or the cold front is strong, such as the question.

Freezing rain is a kind of disastrous weather in early winter or late winter and early spring, which is composed of ice-water mixture and freezes immediately after colliding with objects with a temperature below 0℃. Raindrops below 0℃ can remain supercooled in air with a temperature slightly lower than 0℃, and their appearance is the same as that of ordinary raindrops. When they fall on an object with a temperature below 0℃, they will immediately freeze into a smooth and transparent ice layer, which is called snowball. Severe snowstorms will crush trees and telephone poles, stop communication and power supply, hinder road and railway traffic, and threaten the flight safety of aircraft.

Freezing rain is a weather phenomenon seen in early winter or late winter and early spring. See the left figure for its meteorological symbols.

When the strong cold air meets the southbound warm and humid airflow, the cold air is inserted under the warm air like a wedge, and the near-surface temperature drops below zero, and the humid warm air is lifted to form clouds, causing rainfall. When raindrops fall from the sky, poles, trees, vegetation and roads will be frozen with a layer of crystal clear thin ice because the near-surface temperature is lower than 0℃, which is called "freezing rain" in meteorology. In some areas of southern China, freezing rain is also called "falling ice", while in northern China, freezing rain is called "ground oil" or "flowing ice". [ 1]

Freezing rain mostly occurs in winter and early spring. In China, Guizhou is the region with more freezing rain, followed by Hunan, Jiangxi, Hubei, Henan, Anhui, Jiangsu, Shandong, Hebei, Shaanxi, Gansu and southern Liaoning. Among them, there are more mountains than plains, and the mountains are the most. When freezing rain accumulates to a certain extent, it is not only harmful, but also very harmful.
