What is the cold wave standard stipulated by the Meteorological Bureau?

The cold wave weather standard stipulated by China Meteorological Bureau: when cold air passes through the border, the temperature drops above 10℃ within 24 hours, and the lowest temperature on this day is below 5℃, which is called a cold wave. Every time the intensity of cold air is different, it can be divided into strong cold air and cold air activity according to the extent of cooling.

China has a vast territory, and the climate between north and south is quite different. Strong cold air travels a long distance, and the intensity of reaching the south is obviously weakened, so it is difficult to reach the specified cold wave standard. Therefore, according to the local actual situation, each province has formulated the standard for releasing cold air intensity. Cold wave can be divided into national cold wave and regional cold wave (such as northern cold wave).

In winter, all localities should listen; Watch the weather forecast, and be prepared to guard against strong winds and cool down in time.
