Is there a cold wave in Guangdong?

Cold wave is a natural weather phenomenon. As the name implies, cold air flows like a flood. It belongs to a form of air (cold air) flow. Cold wave is cold air from high latitudes, which rapidly intensifies and invades middle and low latitudes under certain weather conditions, resulting in a wide range of severe cooling, strong winds and rain and snow weather along the way. This cold air invading south to a certain standard 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 it strikes, the temperature will drop sharply, accompanied by strong winds, rain and snow, which will have a serious impact on industrial and agricultural production, people's lives and human health.

Meteorological definition

Cold wave is a strong cold air activity that the polar regions or cold zones invade low latitudes. Not all cold air intrusion processes are called cold waves. Generally, after cold air invades a place, if the temperature in those places can be reduced by more than 8 degrees Celsius in a day (24 hours), and the lowest temperature in that day is below 4 degrees Celsius, this cold air is called a cold wave.

Guangdong Meteorological Bureau defines the cold wave standard as: the daily average temperature drops above 8℃ in one day, or the average temperature drops sharply 10℃ in two days, and the minimum temperature drops below 5℃. Cold wave is a kind of disastrous weather in winter, and people are used to calling it cold wave. This cold air invading south to a certain standard is called a cold wave.
