What causes sandstorms? What should be done to prevent and control sandstorms?

Sandstorms can cause inconvenience and impact on people's travel and respiratory system. It is a natural disaster weather and is not friendly to us humans. We need to better understand the causes of sandstorms and what should be done to prevent and control them. Only by understanding the precautions for sandstorm weather, can we continuously improve and make our home more beautiful.

What causes sandstorms?

The reason for the formation of sandstorms is that there is little precipitation in arid areas in winter and spring. In addition, the surface is dry and loose, and has a weak resistance to wind erosion. Therefore, when strong winds blow, a large amount of sand and dust will be swept into the air, forming sandstorm weather. The formation of sandstorms requires three necessary conditions: sand and dust materials, strong winds, and unstable air conditions. Sandstorms are the general term for sandstorms and dust storms, and are a sign of desertification.

Sand Storm:

Dust storm is the general term for sandstorm and dust storm, which is a sign of desertification. It refers to a disastrous weather phenomenon with low probability and high harm, characterized by suddenness and short duration, when strong winds blow up a large amount of sand and dust from the ground, making the horizontal visibility less than 1 km. Sandstorm refers to a sand-carrying storm formed by strong winds blowing a large amount of sand into the near-ground layer; dust storm refers to a storm formed by strong winds blowing a large amount of dust and other fine particles into the high altitude.

What should be done to prevent sandstorms?

1. Strengthen environmental protection and raise environmental protection to the level of law.

2. Restore vegetation and strengthen the biological protection system to prevent sandstorms. Protect and restore forest and grass vegetation in accordance with the law to prevent further expansion of land desertification and reduce the source of sandstorms as much as possible.

3. Formulate disaster prevention, disaster resistance and disaster relief plans according to the local conditions of different regions, actively promote various disaster reduction technologies, and build a number of demonstration projects to gradually promote them from point to surface, and further improve the regional comprehensive defense system.

4. Strengthen scientific publicity on the occurrence and harm of sandstorms and their relationship with human activities, so that people can realize that once the environment they live in is destroyed, it will be difficult to restore. It will not only aggravate natural disasters such as sandstorms, but also form a vicious circle. Therefore, people must consciously protect their living environment.

5. Plant plants suitable for growing in arid desert areas, such as sea buckthorn, in desert areas to form a ground cover plant layer, thereby improving the ground cover environment, fixing the soil, reducing wind speed, increasing air humidity, and improving the microclimate environment.

6. Plant native varieties of low shrubs and small trees on the edge of the desert to improve vegetation distribution.

Notes on sandstorm weather

1. When a sandstorm comes, do not hide under big trees, billboards or dangerous buildings to prevent being blown down and injured by the strong wind. Also, do not hide under electric poles to prevent electric shock.

2. Reduce going out when a sandstorm comes. If it is really not possible, wear a mask when traveling and try to travel with others.

3. When a sandstorm comes, hide in a sheltered place as quickly as possible. If there are no buildings around and no sheltered place to hide, you can cover your face and mouth and nose with clothes to prevent sand and dust from entering your mouth and nose.

4. If dust blows into your eyes during sandstorms, do not rub your eyes with dirty hands. Instead, rinse your eyes with clean water or use eye drops as soon as possible to keep them moist so that dust and sand can flow out. If you still feel uncomfortable, seek medical attention immediately.

5. When people enter indoors from the outdoors in windy and sandy weather, they should wash their faces in time, rinse their mouths with clean water, clear their nasal cavity, take a bath if conditions permit, and change clothes in time to keep their bodies clean and comfortable.
