Recently, sandstorms have been frequent in Beijing. How is it formed?

Sandstorm weather is mainly due to spring, the earth has not recovered, the surface is dry and there is little rainfall. The wind blows, and the wind blows into the air with dust, eventually forming sandstorm weather. Under normal circumstances, sandstorms mainly occur in the north, especially in Inner Mongolia and other places, with occasional sandstorms.

1, in order to prevent sandstorm weather, more measures should be taken. For example, low-carbon travel, choose to walk or take the subway. Reduce driving, because driving will release a lot of waste gas, which is very harmful to the air and will form a greenhouse effect after a long time. Not only that, we should also plant more green plants. Because green plants can effectively absorb carbon dioxide and release oxygen. A variety of green plants can make our air rich in oxygen, which can not only purify the air, but also prevent smog weather and sandstorm weather. Besides, green plants can beautify the environment. If there are flowers and trees everywhere in our ecological environment, it would be great. Not only that, we should also protect our environment, don't cut down trees indiscriminately, and don't pick flowers and plants at will. First, because flowers and plants have life, we have no right to deprive them of life. Second, the ecological environment needs green plants. If we hurt them at will, it will not only hurt their lives, but also affect our good environment.

2. In sandstorm weather, protective measures should be taken. When we go out, we should wear masks. The purpose of this is to effectively isolate yellow dust particles, so as not to be inhaled into the lungs, causing symptoms such as cough. You should also close the doors and windows when you are at home. In this way, the dust particles outside will not drift into the room, causing secondary pollution. Drink plenty of water when you go out, so as to be less dry in a dry sandstorm environment, especially when dust particles stick to our faces. Drinking more water can reduce the dry reaction of our faces.
