How is the cold wave weather formed?

In winter, the high latitudes receive little solar heat, and the Arctic and high latitudes are covered with a lot of snow and ice, and the heat reflected by the surface is also great. Therefore, the temperature in the Arctic and high latitudes is very low, and dry cold air gathers there, forming a dense cold air mass. When these cold air masses accumulate to a certain extent, they will flow from the source to low latitudes, which is called cold air activity. When a strong cold air mass moves from high latitude to low latitude, a cold wave weather process is formed.

Cold wave weather is a large-scale severe cooling phenomenon in the winter half year under the specific circulation situation at high latitude. Where cold air passes, there will be cooling, strong wind, rain, snow or freezing weather one after another, which has a wide range of influence. Heavy snow, freezing, heavy rain, etc. Causing traffic jams and interruption of telecommunications; Strong winds in coastal areas will cause storm surges and capsizing accidents at sea; Strong cooling has the most serious freezing damage to crops, melons and tropical crops. The cold wave has a great influence on industrial and agricultural production and people's daily life. This is a disastrous weather.
