When will the windy weather end?
Experts from China Weather Network will interpret it for you.
The largest wind gust in Beijing's 5 district has reached a level 8 gale for three consecutive days
On May 4th, many friends who returned to Beijing by plane during the May 1st holiday felt the discomfort of dizziness, which was related to the windy weather in Beijing that day.
Monitoring showed that, under the influence of strong northerly winds behind the high-altitude cold vortex, Beijing gusts once reached level 8 on May 4.
One day later, strong winds in Beijing resumed. Data monitoring from 13:00 today showed that the wind in Beijing has increased significantly. The gust winds in Yanqing, Changping, Mentougou, Haidian, and Shijingshan have reached levels 7 and 8, and the visibility has dropped to 3 to 5 kilometers.
According to Hu Xiao, chief meteorologist of China Weather Network, the historical extreme value of Beijing gale was 22.8 m/s, which appeared on May 5, 2010. Today, the wind at the southern suburbs observatory in Beijing can reach 20 m/s. If it reaches it, it will be close to 20 m/s. The biggest wind gust in May 10th.

After this process is over, there will be additional cold air going south, and Beijing will encounter strong winds the day after tomorrow. The northerly winds can still reach about level 4, and it is expected that the process of strong winds at night will tend to end.
Mongolian cyclone and cold air seamlessly connect with Beijing's gale, "not offline"
From a perennial point of view, from March to May is the season of high winds in Beijing. There are not only many strong wind days in spring, but also relatively strong winds.
Hu Xiao introduced that Beijing is windy in spring because the cold air in the north is still active in spring.
Due to the large pressure gradient and the superposition of strong wind caused by the sinking movement of the cold air, the wind force in spring will be more obvious.
Hu Xiao analyzed that the frequent impact of the Beijing gale this time is mainly due to the continuous impact of the Mongolian cyclone, and the location of the Mongolian cyclone is closer to the south, which affects the region more deeply in my country, of which the gales will be particularly strong today and tomorrow.
The day after tomorrow, the cold air will be added to the south, and Beijing will still be "not offline" in the windy weather during the day.
