What is cold wave weather?

Cold wave weather refers to a weather phenomenon in which a cold wave passes through an area and causes a sharp drop in temperature, accompanied by strong winds and precipitation. The cold wave standard of the Central Meteorological Observatory stipulates that the intensity of cold air activity is determined by a combination of process cooling (the beginning and end of the influence of cold air, the difference between the highest and lowest daily average temperature) and negative temperature anomalies.

Cold wave weather, also known as cold wave, is one of the main weather phenomena in winter. Generally speaking, cold wave weather refers to a high pressure generated in the north. The cold high pressure moves southward along the northwest airflow behind the westerly trough. Invasion, and finally went to sea to change gender. During a cold wave attack, the cold air causes local temperatures to plummet, ground pressure to rise sharply, and sometimes even causes strong winds and large waves. Cold wave weather has the widest impact among all severe weather conditions. It can generally affect about 10 million square kilometers in winter. Tropical cyclones and extratropical cyclones cannot reach such a huge range of influence.

Cold wave weather is a kind of disastrous weather in winter. People are accustomed to calling cold waves cold waves. The so-called cold wave refers to cold air from high latitudes that rapidly intensifies under specific weather conditions and invades mid- and low-latitudes, causing severe cooling, strong winds, rain and snow in areas along the way. This kind of cold air that reaches a certain level when it invades south is called a cold wave.

my country’s Meteorological Department stipulates that when the cooling caused by the intrusion of cold air reaches more than 10 degrees Celsius within a day, and the minimum temperature is below 5 degrees Celsius, this cold air outbreak process is called a cold wave process.
