The cold air cools down south. Climate change in provinces and cities

After the Spring Festival, you must feel the climate rising, and some provinces and cities even exceed 20℃, but don't take it lightly at once. The cold air will go south next week, which will bring very serious cooling to most parts of our country. Remember to add clothes in time.

The cold air going south will bring about a sudden drop in temperature. According to the forecast of the Central Meteorological Observatory, most parts of the country will still warm up today, and the area from the Yellow River Basin to the middle and lower reaches of the Yangtze River will warm up to 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℃ locally. Pay attention to adding clothes to keep warm!

Among them, the warmer this weekend, the more obvious 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 changes in various provinces and cities, such as Zhengzhou, Henan Province, the highest temperature reached 26℃ on the 20th, and further rose to 27℃ on the 20th, breaking the record of high temperature in the same period in February in the past 70 years, but then turned sharply, and it is expected to be only 15℃ on the 22nd.

It was as low as 5℃ on the 24th and returned to 8℃ on the 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, which is rare in February.

Due to the large temperature rise, the cooling caused by cold air will be relatively 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. Cold air going south will bring about a sharp drop in temperature.

This cold air affects Northeast China, North China, Huanghuai, Jianghuai and other places, and the local cooling rate can exceed 10℃

Liu Mei, chief forecaster of Jiangsu Meteorological Observatory, said: The highest temperature is 23℃ to 24℃ from 20th to 2nd1day, and the highest temperature in most parts of our province is10/5℃ from 22nd to 23rd.
