Weather signs in Beijing

The first rain in Beijing turned out to be a rain Mud rain? In fact, this is the role of sandstorm and spring rain. As we all know, sandstorms are very easy to flood in spring in the north. If it rains, it is easy to carry sandstorms. Mud rain? This is because sandstorms contain a lot of sand and soil.

In fact, spring in the north has been affected by sandstorms. Because the north of China is close to the Siberian Plateau and the Loess Plateau, when the northwest wind blows every spring, there will be a large number of sandstorms raging in the north of China, which makes people feel difficult to breathe and the environment will become very poor. But if the spring rain comes, this situation will slow down, because the rain can press down the soil in the sandstorm, although it becomes? Mud rain? Some of them are not beautiful, but at least they can remove dust storms from the air.

First, the formation of sandstorms

Sandstorm is actually the dust on the plateau swept to the plain by the north wind. Once the sandstorm is formed, it will seriously affect people's lives, for example, it will affect people's breathing. Many diseases are caused by some harmful substances in the air. Sandstorms contain many substances harmful to breathing, which will add more burden to our lungs.

Second, spring rain is as expensive as oil.

In fact, it seldom rains in spring in the north, because it is dry in spring in the north, so it seldom rains. Therefore, there is an ancient saying in China that spring rain is as expensive as oil to describe its preciousness. When the spring rain comes, many sandstorms will dissipate. This is also the first rain in Beijing. Mud rain? The reason is that the spring rain hit the soil and sand in the sandstorm to the ground.

Third,? Mud rain? Formation, sandstorm reduction

Mud rain? The formation indicates that the sandstorm will soon pass, because the spring rain is coming and summer will begin soon. When summer comes, the air humidity will rise and the wind direction will become the southeast monsoon. At this time, the sandstorm phenomenon will be greatly reduced.

What was the first spring rain in Beijing? Mud rain? In the final analysis, it is because the sandstorm is more serious. However, I believe that under the protection of the environment, the phenomenon of sandstorms will become less and less.
