On the morning of October 26, when the sun shone into the East Asian continent, the northeast of North China's Huanghuai and the Yellow Sea bohai Sea in northern China looked like they were covered with a layer of ash and appeared gray, which was actually the result of the accumulation of pollutants near the ground.
This morning, pollutants in North China, Huanghuai and the southern part of the Northeast Plain are still piling up in large quantities, resulting in poor air quality in places such as Beijing-Tianjin-Hebei, Shandong, Liaoning, and other places. Monitoring data show that at 7 o'clock in the morning of October 26, large-scale mild-moderate pollution appeared in the northeast of Huanghuai in north China, and even heavy pollution appeared in a dry city such as Tianjin, Langfang, Qinhuangdao and Jinzhou, which is a calm period of intermittent cold air, and the haze weather in many parts of northern China is rapidly developing and strengthening.
The good news is that although the haze weather is menacing, it is not long-lasting, because a new cold air has gradually affected many parts of the north of our country from today. New cold air is strengthening winds in places like North China, blowing away pollutants that have accumulated in the North China Plain. Monitoring data from 11 a.m. shows that the cold air from the south is blowing fresh air from the grassland on the dam into the northern part of the North China Plain, and the air in many parts of Beijing in the north of the North China Plain has rapidly turned better, and the air quality index (AQI) in many places has dropped to about 20, which is a fairly high-quality air level. In Tianjin, Hebei, where cold air has not yet touched, it is still under moderate-heavy pollution control.
As the north wind brought by cold air further spreads in the North China Plain and northeast China, the haze will also be quickly driven away by the north wind, and the forecast of the Central Meteorological Observatory believes that from October 26, the atmospheric diffusion conditions in many places in the north will improve, and the haze weather will gradually weaken or dissipate from north to south.
However, the intensity of this cold air is not strong, the impact time is relatively limited, the Central Meteorological Observatory also pointed out in the forecast, from October 29, the atmospheric diffusion conditions in the central and southern parts of North China and the central and eastern parts of Huanghuai have deteriorated again, and there are light to moderate haze in some areas and a short-term severe haze in the local area. Therefore, recently friends in many places in Huanghuai, North China, should pay attention to the air situation when carrying out outdoor activities, and sensitive groups of people should be properly protected during the period of haze development.
