The temperature plummeted by nearly 20℃, and cold wave warnings were issued many times. Why is there such a cold weather this year?

When everyone was immersed in the joy of spring, traveling everywhere and hiking everywhere, many parts of the country actually issued cold wave warnings, and the temperature plummeted by more than 20 degrees Celsius and returned to winter in one second. The cold weather this year is mainly because the cold air in the air is very active, and most parts of the country have been affected by the cold wave.

First, the temperature plummeted by 20℃, and cold wave warnings were issued many times.

From March 20 12 15, the weather in many cities in our country is like riding a roller coaster. On the first day, it is always ups and downs, wearing short-sleeved skirts and starting to wear cotton-padded jackets the next day, so there is also a phenomenon of disorderly dressing in the streets. In early spring, the temperature fluctuates greatly in many places in China. For example, the highest temperatures in southern Gansu, Sichuan, Hubei and Anhui all exceeded the historical extremes. Even the average temperature for five consecutive days in many places has reached the standard of summer, which is unacceptable to many people.

However, according to the forecast of the Central Meteorological Observatory, in the coming week of March 15, there will be a large-scale cooling in many parts of the country, especially in the north, and the cooling rate will directly exceed 20 degrees Celsius. Zibo, Shandong, Shijiazhuang, Shandong and other places have issued cold wave blue warning, which is also called "cold in spring" among the people.

Second, why is there such weather as late spring cold?

In fact, the cold weather in late spring must have something to do with cold air and warm air. In late February, 2022, the cold air activity was relatively weak, which had little impact on the temperature in China, while the warm air activity was relatively strong, and the temperature in many parts of the country began to slowly rise. However, due to strong heating activities, summer suddenly arrived in many parts of the country, and there was a big warming phenomenon. Moreover, due to the influence of direct sunlight and other factors, the temperature in the polar regions is still relatively low, and the cold air has not completely disappeared. When these cold air developed strong enough, due to the cooperation of various factors, it began to go south, affecting most parts of China.
