The heavy fog in Chengdu was comparable to Silent Hill. What was the visibility level at that time?

At around seven o'clock in the morning, the visibility was less than 20 meters. At noon and afternoon, the fog gradually dissipated, but the visibility was still less than 100 meters. On December 27, Chengdu was shrouded in heavy fog for a whole day. On the 28th, the fog still existed, but it was better than the fog on the 27th. Due to the heavy fog, many highways around Chengdu have been closed because the visibility is so low. It is no exaggeration to say that you can't see clearly what's ahead ten meters away.

It is said that at dawn, the fog is the thickest and the visibility is the lowest. The visibility on the ground is extremely low. If you look from a high place, you will not be able to see the high-rise buildings on the opposite side. And know how big it is. At noon, although the fog gradually dissipated, the visibility only increased by fifty meters at most, so it is not an exaggeration to describe it as Silent Hill. Regarding this heavy fog, Chengdu netizens are actually used to it, because in the Chengdu Basin, thick fog often occurs in winter, so netizens also joked that it is a "wonderland".

In fact, after living in Chengdu for so many years, there are many times of heavy fog, but it disperses very quickly, unlike this fog, which took two days to disperse. And the fog this time gave me the feeling that it was not white, but more like gray. It looked gray, like "smog". In addition, the weather that day was cloudy, so the fog looked thicker. More gray.

According to the forecast from the meteorological station, the weather in Chengdu will still be cloudy in the next few days, and there may also be light rain, so dense fog may occur again, so here is a reminder to drive Friends traveling must drive slower and more steadily. After all, visibility is too low in dense fog and traffic accidents are easy to occur. People who go out are also reminded to wear thick clothes when going out, keep warm and prevent colds, and also wear masks when traveling. After all, wearing a mask during special periods can not only prevent infection, but also block fog in dense fog. haze.
