The Ministry of Ecology and Environment informed the media yesterday that according to the consultation results of the China Environmental Monitoring Center and relevant provincial environmental monitoring centers, it is expected to be affected by unfavorable weather factors such as static stability, high humidity, and strong inversion.
It is expected to be from November 30 to December 3 , There will be a regional severely polluted weather process in North China, East China and Northwest China.
The impact will include the Beijing-Tianjin-Hebei and surrounding areas, the Fenwei Plain and the northern part of the Yangtze River Delta.
The Ministry of Ecology and Environment informed the media yesterday that according to the consultation results of the China Environmental Monitoring Center and relevant provincial environmental monitoring centers, it is expected to be affected by the previous sand and dust retention due to the influence of unfavorable meteorological factors such as static stability, high humidity and strong inversion.
On the evening of November 29, the air quality of some cities in Shanxi, Shandong, Henan, Jiangsu, Anhui, and Shaanxi was still at moderate to severe pollution levels.
It is expected that under the continuous adverse weather conditions from November 30 to December 3, the accumulation and transmission of pollutants will add to the impact of the previous sand and dust retention, and the pollution will be further aggravated.
The details are as follows.
Affected by the previous sand and dust retention, as of Beijing-Tianjin-Hebei and surrounding areas: From November 30 to December 3, Beijing-Tianjin-Hebei and surrounding areas are controlled by the easterly high pressure system, and the near ground is dominated by weak southerly winds.
With adverse weather conditions such as strong temperature inversion and high humidity throughout the day, it is expected that air quality in the central and southern Beijing-Tianjin-Hebei, western Shandong, and most parts of Henan will continue to reach severe pollution levels.
Superimposed on the previous dust residues, some cities may reach serious pollution.
Beijing-Tianjin-Hebei and surrounding areas: Among them, from the evening of December 1st to 2nd, with the foggy weather, the humidity in the area gradually increased from south to north, and the moisture absorption of fine particles increased significantly, which was the heaviest period of the pollution process.
Among them, starting from the morning of the 3rd, due to possible cold air processes, air quality has gradually improved from northwest to southeast.
Fen-Wei Plain: Fen-Wei Plain: From November 30, the regional diffusion conditions have deteriorated, the overall relative humidity is relatively high, and the impact of dust residues in the previous period will be superimposed.
The air quality in the cities of Guanzhong, Shanxi, and northwestern Henan will reach medium to medium Severe pollution level.
From December 1-2, the diffusion conditions continued to deteriorate and the pollution situation became worse.
The air quality of the cities in the region was mainly heavily polluted.
From the afternoon of the 2nd to the 3rd, the air quality of the region gradually moved from west to east due to the combined influence of cold air and precipitation.
improve.
The northern part of the Yangtze River Delta region: The northern part of the Yangtze River Delta region: On November 30, the region was controlled by the bottom of the high pressure, and the relative humidity near the ground was relatively high.
The air quality in most of Jiangsu Province and the central and northern cities of Anhui Province was mainly moderately to severely polluted.
From December 1-2, the regional southerly winds further strengthened, and pollutants accumulate to the north.
It is expected that the urban air quality in the northern part of the Yangtze River Delta will be heavily polluted.
In the second half of December 2, the Yangtze River Delta region was affected by low pressure and inverted troughs.
There was precipitation in some areas and the pollution situation has eased.
However, some cities in northwestern Jiangsu and northern Anhui may still experience severe pollution.
Air quality is expected to be gradually increased after 3 days.
ease.
The Ministry of Ecology and Environment has sent letters to the People’s Governments of Beijing, Tianjin, Hebei, Shanxi, Jiangsu, Anhui, Shandong, Henan, and Shaanxi Provinces, informing them of air quality forecasts and forecasts, and requesting local governments to promptly respond to actual conditions.
Initiate, maintain, and adjust the corresponding level of early warning, effectively implement various emission reduction measures, alleviate the impact of heavy pollution weather, and protect the health of the people to the greatest extent.
The Ministry of Ecology and Environment has dispatched on-site working groups in the Beijing-Tianjin-Hebei air pollution transmission channel cities and the Fenwei Plain to urge the localities to implement emergency emission reduction measures.
