It is currently at the peak of the Spring Festival, which will give people Travel and life have a big impact, please pay attention to prevention.
The cause of freezing rain
Freezing rain is composed of supercooled water droplets. When they fall from the sky, due to the low temperature near the ground, a layer of crystal clear and thin ice freezes on the poles, trees, vegetation and road surfaces. This is a weather phenomenon seen in the early winter or early winter and early spring. It is called "freezing rain" or "rain raft" in meteorology. In some areas of southern China, freezing rain is also called “ice iceâ€, and in the north it is called “ground oilâ€.
High-incidence area of ​​frozen rain in China
The area with more freezing rain in China is Guizhou Province, followed by Hunan, Jiangxi, Hubei, Henan, Anhui, Jiangsu and Shandong, Hebei, Shaanxi, Gansu, and southern Liaoning. More than the plains, the highest mountain. Most of the freezing rains in the Jianghuai area occurred in the first half of January to the middle and upper months of February. The starting date has the characteristics of north and early south, mountainous area and plain, and the end date is reversed.
The danger of freezing rain
Rain falls from the sky and forms ice, can it cause damage? Yes, when this ice accumulates to a certain extent, it is not only harmful, but also harmful. The thickness of the frozen rain is generally 10 to 20 mm, and the thickest is 30 to 40 mm. After the wire is frozen, it will break when it is cold contracted and the weight of the frozen rain. Sometimes, the rows of poles are pulled down, interrupting telecommunications and power transmission. Road traffic was blocked by ground freezing and traffic accidents increased. Severe freezing rain will crush the house. When the plane flies in the clouds with cold water droplets, the wings and propellers will accumulate water, which will affect the aerodynamic performance of the aircraft and cause damage. If the field is frozen, the winter wheat will be frozen, or the seedlings planted in early spring will be frozen. In addition, freezing rain can also destroy young forests, frostbite fruit trees and so on.
How to deal with freezing rain
For ice accretion on the road caused by freezing rain, salt and ice should be sprayed in time, and manpower should be cleaned. In the event of an accident, a clear sign should be placed at the scene of the incident. The freezing rain will fall on the pole and form an icicle.

Drivers and friends should slow down in the freezing rain, do not overtake, accelerate, sharp turn or emergency braking. Tire chains should be installed in time. De-icing equipment should be installed on the plane or simply bypass the freezing rain area.
