What does the cold wave mean?

Cold wave is a natural weather phenomenon. Refers to the cold air from high latitudes, which is rapidly strengthened in a specific weather situation and invades the middle and low latitudes, causing a wide range of severe cooling, strong winds and rain and snow weather along the way. When this cold air reaches a certain standard, it is called a cold wave.

Cold wave is cold air from polar regions or cold zones in winter, which invades the middle and low latitudes on a large scale like tides. When a cold wave strikes, the temperature will drop sharply, accompanied by strong winds, rain and snow. It has a serious impact on industrial and agricultural production, people's lives and human health.

The cold wave invading China mainly broke out in the Arctic, Siberia, Russia and Mongolia.

Extended data:

The freezing rain, snow and ice weather brought by the cold wave is extremely harmful to transportation. The moving speed of the cold wave is tens of thousands of meters per hour, which is similar to the speed of the train.

There are three routes that affect the cold wave in China: one is the west road. This is the earliest and most frequent route affecting China. Strong cold air starts from the North Pole, goes south through western Siberia, enters China and Xinjiang, and then invades North China, Central Plains, South China and even Southwest China along the Hexi Corridor.

The second is the middle road. Strong cold air flows from Siberia and Lake Baikal in Mongolia, passes through Inner Mongolia Autonomous Region of China, enters North China, and reaches the southeast coastal areas.

The third road is East Road. Cold air flows south from northeast Siberia, sometimes through northeast China, sometimes through the Sea of Japan and the Korean Peninsula, and invades the eastern coast of China. The main force of the cold wave going south from this route is eastward, which is generally not very strong and the frequency will not be too much.
