Climate change in provinces and cities where cold air cools down southward.

After the Spring Festival, everyone must have felt the climate rise, and some provinces and cities even exceeded 20. But don't take it too lightly at once. Next week, cold air will head south, which will bring very serious cooling to most parts of China. So, remember to add clothes in time.

The cold air going south will bring about a sharp drop in temperature.

The Central Meteorological Observatory predicts that most parts of the country will warm up today, and the temperature from the Yellow River basin to the middle and lower reaches of the Yangtze River can reach April-May. However, starting from next week, a cold air will affect most areas south and north of the Yangtze River, bringing about a sharp drop in temperature. The cumulative cooling range can generally reach about 10, and even exceed 20 in some areas. Pay attention to adding clothes to keep warm!

Among them, the warmer this weekend, the greater the difference between cold and warm when hungry, and the temperature fluctuation is like riding a roller coaster.

Cold air going south will bring about a sudden drop in temperature: Zhengzhou will drop from 27 to 5.

Climate change in provinces and cities

Taking Zhengzhou, Henan Province as an example, the highest temperature reached 262 1 on the 20th, and further rose to 27 10, continuously breaking the record of high temperature in February in recent 70 years, but then turned sharply. It is estimated that only 15 will be available on 22nd, even as low as 5 on 24th, and it will return to 8 on 25th.

Nanjing will also drop from 25 to 1 1 in five days, and manufacturers will drop from 23 to 1 1 overnight.

So, why has the temperature fluctuated so much recently?

Wang, a meteorologist from China Weather Network, analyzed that since February this year, the temperature in most parts of the country has generally been higher than normal. In recent days, the sky is clear, the air is dry, and the radiation in the clear sky is relatively strong, so the temperature rises rapidly.

Especially in North China, Huanghuai and other places, the influence of cold air is rare, and there is warm advection transportation, resulting in a rare warm situation in February.

As the temperature rises sharply, the cooling brought by cold air will be more obvious next week.

Don't be fooled by the warmth of the day. Hebei, Inner Mongolia and Jiangsu issued cold wave blue warning signals, while Hebei, Tianjin and Liaoning issued gale blue warning signals. The cold air in the south will bring obvious cooling. This cold air will affect Northeast China, North China, Huanghuai, Jianghuai and other places, and the local cooling rate can exceed 10.

Liu Mei 10, the chief forecaster of Jiangsu Meteorological Observatory, will have a round of cooling: the highest temperature is 23-24 from 20th to 2nd1day, and the highest temperature is 10 to 15 from 22nd to 23rd in most parts of our province, with the lowest temperature below 5.
