Chinanews, August 1st. According to the WeChat official account of the Ministry of Ecology and Environment, the Ministry of Ecology and Environment issued a national air quality forecast for the next three days on August 1. The next three days (August 2-August 4), most of the country The air quality is generally good, and there may be moderate ozone pollution in North China.
According to the results of the joint consultation between the China Environmental Monitoring Center and the regional air quality forecasting centers and relevant provincial air quality forecasting departments, the future air quality situation of the country and key regions is predicted as follows:
National air quality situation
In the next three days, the air quality in most parts of the country will be generally better, and there may be moderate ozone pollution in North China.
On the 2nd, most parts of Northeast China, North China, East China, South China, Northwest China, and Southwest China were mainly of good quality, with mild local pollution. Southern Xinjiang may suffer from moderate to severe pollution due to sand and dust; and the central and southern parts of North China were moderate to mild. Mainly pollution.
From the 3rd to 4th, the northeast, the northern part of the north, the east, the south, the northwest, and most of the southwest were mainly high-quality, with mild local pollution; the central and southern parts of northern China were mainly polluted with good to light, and some cities might have moderate ozone pollution .
Beijing-Tianjin and surrounding regional center forecasts
The process of light to moderate ozone pollution indicates that in the next ten days, due to weak cold air disturbance and systematic precipitation, the air quality will be generally better. On the 3-4 days, the local temperature in the central and southern parts of the region is relatively high, with less cloud cover, and some cities in the central part may have moderate ozone pollution
On the 4th, the temperature in the central and southern parts of the region was relatively high, the northern part of the region was mainly good, and the central and southern parts were mainly good to light pollution. Among them, some cities in the central part of the region may have moderate pollution on the 3-4 days. The primary pollutants are ozone and PM2.5.
From the 5th to the 7th, due to the intermittent weak cold air resistance and systematic precipitation, most of the region is mainly good, and in other parts of the region, the northern, Shandong and Henan are mainly good, and the rest of the region is good to light pollution. the Lord. The primary pollutants are ozone and PM2.5
From 8 to 11, the temperature rebounded, and most of the region was dominated by good to light pollution, with ozone being the primary pollutant. The summer weather situation is complex and changeable, and the specific situation needs to be tracked and judged continuously.
Yangtze River Delta Regional Forecast
From 2 to 8 days, the Yangtze River Delta was affected by the subtropical high, and the overall situation was good.
Forecast of Fenwei Plain
On the 2nd, the overall temperature in the Guanzhong area of Shaanxi and southwestern Shanxi was relatively high, which is conducive to ozone production; the northwestern part of Henan was affected by the precipitation process, and ozone production was suppressed. It is estimated that the air quality in Guanzhong area of Shaanxi and southwest Shanxi is mainly good to light pollution, and the air quality in northwestern Henan is mainly good.
From 3 to 7 days, most of the region is affected by frequent precipitation processes, and conditions for atmospheric diffusion and wet removal are favorable. It is estimated that the overall air quality in the region is mainly good, and the eastern part of the region may have mild pollution during the intermittent precipitation period on the 3rd and 5th.
On the 8th, the western part of the region was affected by scattered precipitation, and ozone production slowed down; the temperature in the eastern part rose back, which was conducive to ozone production. It is estimated that the overall air quality in the region is mainly good, and local light pollution may occur in the southwestern part of Shanxi.
Pearl River Delta Regional Forecast
From the 2nd to 6th, affected by the southeast airflow and precipitation, the conditions of atmospheric diffusion and moisture removal in the Pearl River Delta region are better, and the air quality is excellent to good.
From the 7th to the 8th, affected by the southerly airflow and scattered precipitation, the air quality in the Pearl River Delta region was extremely good.
The primary pollutant is ozone.
