Cold waves are called disastrous weather. Where do the cold waves that invade our country come from?

Due to the outbreak of the new coronavirus, the hearts of the Chinese people are pulled together. While we are worried, we are also looking forward to the end of the epidemic. On the day when spring comes, many people also promise that the epidemic will end. A beautiful vow to go see the cherry blossoms together. But this does not seem to be that easy. Due to the recent cold wave in the country, various regions have begun to issue early warnings. Along with this, the temperature has dropped significantly across the country, resulting in the phenomenon of "late spring cold". Most of the northern areas have snowstorms, and the southern areas have heavy rains.

Almost every year, our country encounters a cold wave. When the cold wave comes, it is accompanied by strong winds, which affects our travel. We must be careful of building collapse when we go out. It will also bring snow disasters and freezing damage, which will cause greater harm to agriculture and animal husbandry. Low temperature will destroy and kill plant tissues, especially in the winter wheat areas in the north. The animal husbandry industry also needs to establish forage banks to prepare for cold wave disasters. Adequate preparation.

In fact, the cold wave is not in my country. my country is just a place where other cold air passes, and the cold wave does not originate from the same place every year. Generally there are three regions: mainly in the Arctic, Russian Siberia and Mongolia. There are generally three paths of invasion. The first one is from western Siberia into Xinjiang, China, and advances to the southeast through the Hexi Corridor. The second one is after entering China from central Siberia and Mongolia, then heading south via the Hetao area and central China. The third route is to enter Northeast China from eastern Siberia or eastern Mongolia and go south via North China. It is called the West Road, the Middle Road and the East Road. Sometimes it is even a two-pronged approach. The East and West Roads attack at the same time, causing large-scale rain and snow weather, which is more disastrous.

Before the cold wave comes, relevant departments should strengthen monitoring and make preparations for cold wave prevention and related emergency work according to the cold wave early warning signals. People need to prepare heating equipment in advance, and take special care of the elderly and children to prevent them from frostbite and colds. To reduce the number of trips, the anti-freeze and anti-slip properties of your car should not be underestimated.

During this special period, everyone should protect themselves and wait for the arrival of spring!
