　　According to the Central Meteorological Observatory, from the morning to the morning of the 16th, there were foggy weather in parts of southeastern Hebei, northern and southeastern Shandong, southeastern Henan, north-central Jiangsu, northern Zhejiang, and Liaodong Peninsula. The local visibility was less than 200 meters. Strong dense fog.

The Central Meteorological Observatory continued to issue heavy fog forecasts at 06:00 on the 16th.

From the afternoon of the 17th, due to the combined effects of precipitation and cold air, the haze weather in the above-mentioned areas gradually weakened and dissipated from west to east.

Starting on the 18th, most of the central and eastern regions have good atmospheric diffusion conditions without obvious pollution.

　　In addition, from the 17th to the 19th, a large-scale precipitation and cooling process will occur in the central and eastern regions; parts of southern Shaanxi, northern Sichuan Basin, Jianghan, Huanghuai, Jianghuai, northern Jiangnan, southern North China, and central and southern Northeast China. Heavy rain or heavy rain, local heavy rain in southeastern Liaoning; moderate to heavy snow or sleet in central and eastern Inner Mongolia and northern Northeast China, and heavy snow or heavy snow in local areas; gusts of magnitude 9 or more in the Northeast, the Yellow Sea and the Bohai Sea .

　　According to the official Weibo news of the Beijing Municipal Meteorological Bureau, during the day on the 16th, the Beijing area was controlled by a high-pressure rear weak atmospheric pressure field. The lower levels had high humidity, which was not conducive to the spread of pollutants. The air pollution meteorological conditions in most areas were level 4.

On the night of the 16th, weather conditions in Beijing that were not conducive to the spread of pollutants were maintained, and the level of air pollution weather conditions was level 4.

　　In terms of flights, the Changzhun APP shows that as of press time, the flow of inbound flights at Beijing Capital Airport is normal, while outbound flights have been cancelled in a small area; the flow of inbound and outbound flights at Beijing Daxing Airport is normal.

　　Travel in various places is also affected to varying degrees.

Henan Traffic Radio reported on the morning of the 16th that the Henan Meteorological Observatory will continue to issue a fog orange warning at 06:20 on November 16, 2020: It is expected that in the next 6 hours, the three regions of Xuchang, Luohe and Zhumadian, and the central Xinyang region and Zhoukou region Fog with visibility less than 200 meters will appear in parts of the west, and local visibility less than 50 meters.

Regarding highways, 12 highways in Henan Province are under control due to fog.

　　Shandong Expressway Travel Service reported on the morning of the 16th that due to heavy fog, the traffic police noticed that the G20 Qingyin Expressway Weifang and Weifang West Station Yinchuan direction entrances were temporarily closed.

It is recommended that passing vehicles bypass G309 national highway.

　　In response to the recent air pollution process, Wang Zifa, a member of the Academic Committee of the National Center for Air Pollution Control and Cooperation and a researcher at the Institute of Atmospheric Physics of the Chinese Academy of Sciences, said that entering autumn and winter, especially adverse weather conditions combined with winter heating and industrial production will bring regional pollutant emissions. The increase in volume has led to multiple pollution processes in the Beijing-Tianjin-Hebei region and surrounding areas recently.

　　Wang Zifa predicts that from 16 to 17 in Beijing, light to moderate pollution will prevail, especially in the morning hours of the 16th, due to high relative humidity, heavy fog and cloudy weather, plus nighttime pollutant concentration The effect of rising, the actual senses are poor.

　　From the night of the 17th to the day of the 18th, a heavy precipitation process is expected to pass through North China from west to east.

The forecast team closely followed up and judged that the transit time during this precipitation process is relatively long, and the rainfall is relatively large. It is expected that the pollutants accumulated in the Taihang Piedmont area will be effectively removed, and the air quality in the Beijing-Tianjin-Hebei region and the surrounding area will be significantly improved. After the pollution process is over, the air quality in Beijing will also return to excellent.
