Pay attention when traveling! Atmospheric diffusion conditions will deteriorate in the next three days. Please keep this national visibility map.

China Weather Network News: In the next three days (November 12 to 14), the central and eastern regions of my country will be in an intermittent period of cold air, and atmospheric diffusion conditions will gradually deteriorate. Among them, fog and haze will develop in North China, Huanghuai, Northeast, Sichuan Basin and other places, and visibility will be reduced, even less than 50 meters in some places. China Weather Network has launched a national visibility map to see where visibility is poor and you need to pay attention to travel safety.

With the end of the first cold wave in the second half of the year, most of the central and eastern regions have entered a period of intermittent cold air. The temperature has steadily risen, but fog and haze have also developed and increased. According to the forecast of the Central Meteorological Observatory, atmospheric diffusion conditions will gradually deteriorate in central and southern North China, western Huanghuai and other places in the next three days, with light to moderate haze in some areas and severe local haze.

Yu Qun, a meteorological analyst at China Weather Network, said that the weather conditions in North China, Huanghuai and other places in the next few days are not conducive to the spread of atmospheric pollutants and will reduce visibility. Among them, the 14th is the period when fog and haze have the strongest influence during this round. As the humidity increases, the scope of heavy fog will significantly expand in the early morning, and rain and fog, fog and haze may be mixed.

According to the national visibility map launched by China Weather Network, on the morning of the 12th, visibility was poor in southeastern Beijing, most of Tianjin, eastern and central southern Hebei, and many places with visibility less than 200 meters. The public should travel with caution and drive as little as possible; Liaoning, Shandong, Henan, Jiangsu, Zhejiang, Shanghai, Fujian, Guizhou and other places had low visibility and hazy prospects. The public planned routes in advance before traveling, paid attention to road conditions along the way, and drove slower.

On the morning of the 13th, most of Tianjin, eastern and south-central Hebei and other places still maintained low visibility; visibility in Liaoning, Hunan, Hubei, Chongqing, Guangxi and other places dropped significantly. In some areas, visibility was less than 1 kilometer, and the field of vision was limited. The public was reminded to slow down when driving.

On the morning of the 14th, the scope of influence of fog and haze further expanded. Not only did the visibility in some areas in the Beijing-Tianjin-Hebei area, western and southern Liaoning, central Jilin, western Chongqing, central Henan, central Hubei, southern Jiangsu, and northern Zhejiang be less than 500 meters, the areas with visibility less than 200 meters were also significantly expanded than before, with local areas less than 50 meters. Under low-visibility weather, the Beijing-Harbin, Beijing-Shanghai, Beijing-Hong Kong-Macao, Shanghai-Chengdu, Qingyin and other expressway sections will be affected. It is recommended that the public in the above-mentioned areas should avoid going out as much as possible, check weather forecasts and road condition information in advance, and plan their itinerary reasonably.

This low-visibility weather is mainly concentrated in the central and eastern areas and the Sichuan Basin. In central Inner Mongolia, Gansu, Qinghai, Tibet, western Sichuan and other places, the atmosphere will be clear in the next three days, and visibility will generally remain good, which is conducive to travel.

It is expected that the cold air will become active again after the 14th. Under the combined action of cold air and precipitation, atmospheric diffusion conditions will gradually improve from north to south from the 15th. The fog and haze in the above-mentioned areas will weaken and dissipate, and visibility will gradually improve.

The China Weather Network reminds that autumn and winter are fog and haze-prone periods, and low-visibility weather can easily induce traffic accidents and have a significant impact on highway traffic and flight takeoffs and landings. When traveling in low-visibility weather, the public needs to check the forecast and road conditions and plan their itinerary reasonably; slow down when driving and keep a safe distance between vehicles. At the same time, as fog and haze come, the public is advised to reduce outdoor activities as much as possible, wear masks when going out, and take good health protection.
