What is the continuous pollution in Beijing, Tianjin and Hebei during the Qingming holiday on the 4th and 5th?

From April 2, an air pollution process will begin in Beijing, Tianjin and Hebei and its surrounding areas, which may last until the end of the Qingming holiday. According to the forecast of China National Environmental Monitoring Center, Beijing-Tianjin-Hebei and the surrounding provincial environmental monitoring centers, from March 3 1 day to April 1 day, the atmospheric diffusion conditions are generally favorable, and the air quality in most areas is mainly good to light pollution, and some cities in southern Hebei may have moderate pollution.

On April 2, the atmospheric diffusion conditions deteriorated, and the wind direction gradually changed from northwest to south at night, and the pollution process officially began. From 3rd to 5th, the atmospheric diffusion conditions are unfavorable, and it is expected that there will be moderate to severe pollution process in the central area of Beijing-Tianjin-Hebei, which will affect the major urban agglomerations in the central area of Beijing-Tianjin-Hebei due to the rising temperature, increasing near-surface humidity and systematic southward transportation. Among them, the pollution is the heaviest from the night of the 4th to the 5th, and serious pollution may occur in Beijing, Langfang and Baoding. According to the analysis and judgment of existing meteorological data, it is expected that the pollution situation in the central and northern parts of Beijing, Tianjin and Hebei will be alleviated on the 6 th, and the follow-up situation needs further tracking and judgment.

Chen Jining, Minister of Environmental Protection, stressed that this round of polluted weather lasts for a long time, so it is necessary to make a good forecast of ambient air quality and release early warning information to relevant localities and the public in time. He called for strengthening the supervision of regional hotspot grids and seriously investigating and dealing with enterprises that exceed the standard; Carry out mobile supervision on key cities in the region, go directly to the scene without notice or greeting, directly check the problems, and increase the exposure of various problems found in the inspection; Strengthen dust control, carry out urban dust assessment, and publish the dust situation in various places on a monthly basis; Cooperate with public security, transportation and other departments to strictly investigate motor vehicle emissions, especially heavy diesel vehicles, and severely punish vehicles that exceed the standard according to law.
