The freezing weather in Guizhou and other places will be aggravated, how to prevent it

From January 26th, there will be a large-scale rain and snow weather process in the southern region. This is the third rain and snow weather in the South since the beginning of the year. Snowfall and freezing rain can cause the road to slip and the safety factor is greatly reduced. In the face of the unfavorable weather that is about to begin, we need to be vigilant and guard against it.

Cold air hits the southern frozen rain

Affected by a new cold air, from the 26th to the 28th, the southern part of China will once again face the test of rain and snow, and some areas in Guizhou and Hunan will have freezing rain. 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 ice”, and in the north it is called “ground oil”.

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. The residents along the line should constantly wipe the rain on the wire.

In freezing rain, people should try to reduce their outings. If they go out, they should take measures to prevent cold and keep warm, and pedestrians should pay attention to stay away from or avoid motor vehicles and non-motor vehicles. 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.

Folding Knife

Folding knife, a kind of knife, can be folded. The folding knife is mainly connected with a knife body which can be rotated into by a pivot assembly at the front end of the handle. The knife body is provided with a safety buckle relative to the side of the knife body, and an elastic strip relative to the back end of the knife body. The back end of the knife body is provided with a stop part and a stop concave part which can be butted by the elastic strip, and the safety buckle has a tilted elastic buckle part, The elastic strip is arranged in the holding chamber of the handle, one end of which is fixed, and the other end of which is connected with the stop part of the tool body, so as to provide the thrust to assist the rotation of the handle when the tool body is rotated out of the handle, In addition to the simple semi-automatic operation mode of turning out and positioning by using the elastic auxiliary push knife body, the overall thickness of the folding knife is reduced by the refined and simplified structural design, which is convenient for the collection and carrying of the folding knife and makes the operation of the folding knife easier.
