Yellow fog warnings have been issued in Hebei, Jiangsu, Guizhou and other places. What should I pay attention to when traveling in foggy weather?

Because of the high temperature during the day, the air can contain more water vapor. But at night, the temperature drops and the capacity of water vapor in the air decreases, so most of the water vapor condenses into fog. Especially in autumn and winter, because the night is longer, there is more chance to get smaller without Feng Yun, and the ground heat dissipation is faster than that in summer, which makes the ground temperature drop sharply, and it is easier to make the water vapor in the air near the ground reach saturation from midnight to morning, condense into small water droplets and form fog. Recently, Hebei, Jiangsu, Guizhou and other places have issued yellow fog warnings. What should we pay more attention to in foggy days?

Basic protection in foggy days, pollutants will combine with water vapor in the air and become things that are not easy to spread and settle, so that most pollutants will gather at the height where people often move; Moreover, some harmful substances will become very toxic when combined with water vapor. For example, sulfur dioxide becomes sulfuric acid or sulfite, chlorine water hydrolyzes into hydrogen chloride or hypochlorous acid, and fluoride hydrolyzes into fluoride. Therefore, the air is not very good in foggy days, so it is easy to be inhaled and it is easier to stay in the human body. So go out as little as possible in foggy days, go out for activities as little as possible, and wear masks and scarves outdoors to protect your skin, throat and joints. Middle-aged and elderly people, children and weak people should protect themselves.

Traffic trip reports show that about one quarter to one third of the traffic jams reported by local authorities in China every year are caused by foggy weather. The most significant influence of foggy weather on traffic is speed. Decreasing the vehicle speed will also increase the travel time and delay, which will directly affect the road capacity, especially in the sections with large traffic volume. The reduction of the actual traffic capacity of highway facilities may lead to more serious traffic jams, which will occur in areas with developed networks and high traffic intensity, and will lead to road congestion or even paralysis. So slow down, use the lights correctly, don't brake suddenly, try to keep the distance between cars, do a good job of defogging inside the car, be good at indicating the position with the horn, and pay attention to the choice of driving route.

Protecting the environment smog seems to be related to fog, but in fact fog will endanger people's health. But what if we want to protect the environment and save our environment? Land of abundance? We can turn driving into bicycles, we can put less fireworks and firecrackers, and we can plant more flowers and trees to purify the environment. Only by choosing a low-carbon life can we prevent the occurrence of haze days.

Whether traveling or protecting, safety and health are the first step. Know as much about the weather as possible. It may be better to look at the weather forecast more, do less outdoor sports and do more measures. I hope you have more knowledge about fog prevention and a little awareness in your heart.
