How to deal with dusty weather in spring?
The dust suspended in the atmosphere causes the horizontal visibility of the atmosphere to be less than 10 km.
The dust on the ground is blown up by the strong wind, which makes the air quite turbid, and the horizontal visibility is 1 ~ 10 km.
Dust storms and strong winds blow up the dust on the ground, making the air very turbid, and the horizontal visibility is less than 1 km. When the horizontal visibility is less than 500 meters, it is a strong sandstorm.
Dust weather will have the following adverse effects on human activities:
Environmental pollution: Sandstone and floating dust wrapped in strong wind are everywhere, and the passing air is turbid, choking nose and squinting, which can make the incidence of respiratory diseases soar.
Buried hidden dangers A lot of dust carried by dusty weather blocks the sun, and the weather is gloomy, which leads to the reduction of solar radiation, and the low visibility can last for several hours to more than ten hours. A dark sky can easily make people feel depressed and reduce the efficiency of work and study. In addition, the dusty weather has a great impact on traffic safety, and low visibility leads to frequent traffic accidents, and even leads to the closure of expressway, making it impossible for planes to take off and land normally. In severe cases, it can lead to damage to the glass of cars and trains, and even stop and derail.
In order to prevent the harm caused by dusty weather, people should take the following measures after the occurrence of dusty weather: (1) Avoid staying on billboards and ancient trees. Under the action of strong wind, billboards with unstable installation or ancient trees with unstable foundations are easy to collapse or break, endangering the life safety of pedestrians. (2) Close the doors and windows in time to reduce going out, especially for the elderly and children. People who have to go out had better wear masks, or protect their eyes, mouth and nose with wet towels and scarves to effectively reduce dust inhalation. Wash your hands and face before eating. (3) Because of the dry weather, people should drink more water, replenish the lost water in time, and accelerate the discharge of various metabolic wastes in the body, which is very beneficial to skin and health care. (4) Once you find obvious discomfort, you should go to the hospital in time. (5) Ride a bike less in windy weather, because riding a bike in crosswind may be blown down by strong wind and cause physical injury. (2003.03. 10)
