Rain, snow, strong winds and cooling are about to come online again. What will happen to the temperatures across the country?

According to the current maximum temperature weather forecast, the cumulative temperature in 18 provincial capitals, prefecture-level cities and municipal districts across the country has dropped by more than 10 degrees.

Because the low vortex is northward, the focus of heavy snowfall is obviously northward, bypassing the key snowfall area from Tongliao, Inner Mongolia to Fuxin, Liaoning. Snowfall still poses a certain risk of disaster and will cause great harm to the facility vegetable and animal husbandry industry.

How to prevent colds in extremely cold weather?

When the weather cools down, only by ensuring that you keep yourself warm and protected from colds as much as possible can you actively prevent influenza. At the same time, we also need to improve exercise, enhance resistance, and prevent fatigue, so that the resistance may be stronger. Common colds are caused by viral infections. After cold symptoms occur, such as nasal congestion, runny nose, sore throat, cough, and excessive phlegm, etc. Some patients may also have physical illnesses caused by fever. Some patients also develop digestive tract diseases, such as nausea and vomiting, loss of appetite, diarrhea, etc.

After the occurrence of these diseases, everyone should take medication in time, because the actual effect of drug treatment is the best in the early stages of a common cold. We can choose compound cold medicine preparations and oral analgesics, or antitussive and phlegm medicines. When necessary, we must also treat aggressively with antibiotics.

How is cold air formed?

You need to understand the origin of strong cold air in the Arctic Ocean and Siberia. These two areas have little sunshine for a long time, so the temperature is very low throughout the year. Especially in winter, the temperature here will drop to very low levels, at least the extreme temperature can reach minus 70 degrees. Because the temperature is too low, the local atmosphere is relatively dense. As the density of the atmosphere increases, gases collect and move downward, and the standard pressure increases, creating a powerful stream of cold, high-pressure gas. When high-pressure gases reach a certain level, they rush to lower latitudes and reach China. Of course, the strong cold air generated in the Arctic Ocean will first reach Siberia. The gas here will weaken to a certain extent, but the gas here is still very cold. The cold and high-pressure gas will be reorganized and upgraded, and then invade China to form an extremely cold weather.
