In the next 10 day, Beihuo will encounter three rounds of dust. Why is there always dusty weather?

According to professionals from China Weather Network, there have been six sandstorm weather processes in China, slightly more than the same period of normal years. Dust affects more than 20 provinces. There may be dusty weather in northern China. Since the beginning of this year, the dusty weather affecting our country is not only frequent, but also extensive and intense. Sandstorm refers to a disastrous weather phenomenon in which strong winds roll up a lot of dust from the ground, making the horizontal visibility less than 1 km, which is characterized by suddenness and short duration.

First, the causes of sandstorms.

Sandstorm is a strong wind, which throws everything on the ground into the air and then does great harm to people's nature. As for why it appears, I think it is because people don't pay attention to the environment, wantonly destroy nature, over-exploit resources and wantonly cut down, resulting in soft land, and soil and stone particles are exposed and decomposed by the sun to form countless tiny particles, which are brought inland under the action of monsoon, so there is sandstorm weather. The area north of the Yangtze River will be attacked by sandstorms. It is because the unique geographical environment and climatic factors in the north and northwest of China, including man-made vegetation destruction activities, are the causes of sandstorms.

Second, how to prevent and pay attention to personal safety.

I think the best way is ecological restoration and afforestation. In addition, it is necessary to save water, reduce water pollution, give trees sufficient growth cycle, ensure that the proportion of trees is kept within a reasonable range, and put an end to deforestation.

When there is a sandstorm, we should first avoid going out and try to stay indoors. If we want to go out, we should wear masks and other protection. The second is to do indoor protection and close doors and windows. To reduce the entry of dust and smoke. Humidifier and purifier can be installed indoors or mopping the floor daily to maintain proper air humidity. Drink plenty of water, replenish lost water in time, and accelerate the discharge of waste in the body. Eat more food that nourishes yin and moistens the lungs properly, so as to reduce the damage to the respiratory system and be beneficial to health. Pay attention to skin care, and wash hands, mouth and nose before going in and out.
