I always want to cough in dusty weather.

Mongolian government officials said on March 29th, 20021year that as of that date, there were160,000 livestock dead due to sandstorm weather, and the whereabouts of 230,000 livestock were unknown. Sandstorm weather caused more than a dozen deaths, many yurts and houses were destroyed, and water and electricity were cut off in many places, resulting in different degrees of property losses. Since the spring of this year, there have been many sandstorms in Mongolia, the frequency and intensity of which are higher than those in previous years. Therefore, we have to worry that if they occur frequently, they will inevitably cause greater damage and form a vicious circle.

The reason why sandstorm rages in Mongolia is that Mongolia is a completely landlocked country in both countries. Most of the territory is dominated by desert Gobi, and the natural environment is relatively harsh. It has always been a traditional animal husbandry with the highest number of livestock per capita in the world. Animal husbandry is a pillar industry in Mongolia, but it is this pillar industry that promotes the sandstorm on the other hand. Overgrazing in Mongolia leads to grassland destruction, and land desertification continues to expand, which makes the land with serious desertification wider and provides sufficient dust for sandstorms. There is little precipitation in most parts of Mongolia, the temperature rises sharply in spring, the ground snow melts, and the new buds on the grassland have not yet grown on the ground. Due to the influence of Mongolian cyclone, the average wind force is 6-8. These conditions provide good thermal and dynamic conditions for sandstorms, which are formed under the joint action of sandstorms.

The harm of sandstorm The harm of sandstorm is that when bad weather happens, the wind wraps sand and the dust spreads everywhere, which will cause house collapse, power failure, human and animal casualties and so on. Due to the reduced visibility during sandstorm, traffic accidents will occur, resulting in loss of life and property, and sandstorm weather will also cause environmental pollution, damage plant growth, affect normal photosynthesis, and cause crop yield reduction and other hazards. Sandstorms are also very harmful to human health. The floating dust in the air is mixed with a large number of particles, which will enter the body with the human respiratory tract, destroy the respiratory system, cause nasal congestion, cough, sore throat, and even cause chronic bronchitis. It can also deposit on the skin, causing rashes and redness. These particles enter the eyes, which can also lead to eye diseases and so on.

The most important way to resist sandstorms is to strengthen environmental protection, restore damaged paper cups, strengthen wind and sand fixation, restore vegetation such as trees, and prevent land desertification from providing sand sources for sandstorms. Try not to go out in sandstorm weather. Close the doors and windows at home, seal the gaps in the doors with tape if necessary, and prepare an air purifier at home if possible. If you must go out, you need to do a good job of protection. When you get home, you should protect your face and clean your face immediately, especially your eyes and nostrils.
