The temperature in Beijing is the lowest since 1966. Why did this wave of cold air last so long?

2002117, at the 204th press conference of COVID-19 epidemic prevention and control work in Beijing, Liang Feng, deputy director of Beijing Meteorological Bureau, said that the average temperature in Beijing since winter was -5.2℃, which was 2℃ lower than the same period of last year. Under the attack of strong cold air, the central and eastern regions of China began to have a large-scale strong cooling from 65438+10.6℃, and the lowest temperature at the observatory in the southern suburbs of Beijing reached-19.6℃, the lowest temperature since February/966.

So will the temperature in Beijing drop in the future? Liang Feng said that the influence of this cold air will continue. The minimum temperature of 65438+ 10 can reach-14℃ at night, and 65438+ 10/0 on October 8 should be around -3℃ during the day, which may be accompanied by northerly winds of magnitude 4 or so. 654381October 9, the highest temperature may reach above 0℃, probably at 1℃ and 2℃. However, due to the influence of cold air, the initial cooling range is small, and the temperature will remain low in the next 10 day, so we will feel cold and need to do a good job of cold prevention and warmth. So why did this cold air last so long?

According to the data of the Central Meteorological Observatory, from April 4th to 6th of 2002 1,1year1,the temperature in the eastern part of northwest China, North China, Huanghuai, Jianghuai and other places will drop by about 3~6℃, and the temperature in polar regions will drop by about 8℃. However, from 654381October 6 to 654381October 8, due to the influence of strong cold air, the central and eastern regions will have a temperature drop of about 6~8℃ from north to south, and the local temperature drop range is about 10 ~12℃, and some areas have a 4~6 grade deviation. Weak cold air will first affect North China, Northwest China and Northwest China on June 4th, 65438, and the highest temperature in Urumqi will drop to-16℃ on October 4th, reaching the lowest temperature since winter. 65438+1October 5-65438+1October 6, the temperature in Huanghuai, northeastern North China and eastern Northwest China will also decrease.

65438+10.6, the highest temperatures in Lanzhou, Changchun and Harbin will also reach the lowest in history. There will be another strong cold air coming from October 6, 654381October 8, 65438/KLOC-0. On October 7th, 65438/kloc-0, the temperature in northern China will start to hit a record low in a large area, and the highest temperature in Harbin may drop below minus 20℃. On June 8, 65438, the temperature in the east of Jiangnan, South China and Southwest China will also drop. The highest temperature in Guiyang this winter will fall below 0℃ for the first time, or it may only be -2℃. Meteorologists say that these two cold air will cause long-term cooling. The degree of cold caused this time will be no less than the cold wave at the end of the year.

Because today's winter is particularly cold, Bian Xiao reminds everyone to do a good job of cold protection and warmth when going out.
