When will the cold wave come in 2022?

Lead: In fact, the cold wave weather is equivalent to an enhanced version of cold air, and its arrival is a high-intensity, large-scale cooling, sweeping the north and south of China. Recently, some friends in Bian Xiao want to know in advance when the cold wave will come in 2022. How long will the cold wave last in 2022? Let's have a look.

When will the cold wave come in 2022?

In 2022, the cold wave 1 1 began to come, and there were many cold waves in China, which were already moving. In 2022 165438+ 10, the second wave of cold wave this year was ushered in, which had a great impact and lasted for about 3-7 days. There may be a cold wave at the end of the year. According to the past weather conditions, there will be more than two cold air arrivals at the end of 65438+February. The cold wave is formed under the action of high-altitude air pressure, usually coming from the northwest to China, accompanied by strong winds, rain and snow. Usually, there may be a cold wave in the cold solar term next year, and the specific time depends on the weather forecast.

Due to the wide influence of cold wave weather, the disasters caused are more serious and diverse. Some disasters are directly caused by cold wave weather, such as wind disaster, freezing injury, freezing injury, road icing and snow. Others are indirectly caused, such as rain and snow weather after low temperature, especially in the cold wave, roads are icy and slippery, which leads to a significant increase in traffic accidents. Therefore, we should understand the meaning of cold wave, pay full attention to cold wave weather and cold wave disasters, so as to forecast in advance and take defensive measures in time to reduce and avoid disaster losses.

How long does the cold wave usually last?

It ends in February and March.

There is no exact answer as to how long the cold wave will last. After all, the cold wave is graded, but in the past, it is expected to end in February and March next year. It is understood that the cold wave is a large-scale weather process, that is, the large-scale invasion of cold air from the north into China's south will lead to a sudden drop in temperature along the line. Gale, rain and snow usually occur in late autumn, winter and early spring. Usually after the "great cold day" on February 20, cold waves often appear. When large-scale cold air gathers to a certain extent, it will invade southward on a large scale under the action of appropriate upper-air circulation, forming cold wave weather.

How do residents in different areas cope with cold weather?

Residents in southern China are prone to frostbite and even freeze to death due to lack of warm-keeping measures. They should pay attention to the weather forecast, buy clothes and warm-keeping products in time, and relevant institutions should also publicize health protection knowledge.

Although residents in the northern region have relevant warm-keeping facilities, the temperature drops suddenly when the cold wave comes, so we should further strengthen the warm-keeping protection to prevent carbon monoxide poisoning.

Residents in extremely cold areas should pay attention to the weather forecast, keep warm indoors and by themselves, prevent carbon monoxide poisoning, reserve enough warm items and food in advance, and try not to go out.
