The windy day is coming again. Why are sandstorms and windy weather frequent this year?

Personally, I think this is normal. There were strong winds last year, this year, and every year in the north. My house is naked, and it is windy all year round.

So, how did the strong wind come from?

It is the hot air in the sun that rises and the cold air drops, so the wind is generated when it opens and closes, and it is generated when it rises and falls, so the sandstorm is particularly big now, which has a lot to do with the temperature. And this year, when the clouds are foggy, the air blocked by the clouds will drop, and the air not blocked by the clouds will rise, so the wind will start.

First, the northern plain, the wind can't stop.

Everyone knows that planting trees can prevent sandstorms. In fact, the fundamental function of planting trees is to prevent the wind from blowing the sand on the surface into the air. So from the map, even if many trees are planted in the north, it is still a plain at first glance. The wind on the plain is basically thousands of miles, just like the sand in Alashan has blown to Beijing. Why? Because there is a desert in Alashan, the wind brings the sand to a height of several thousand meters, and then when it meets mild air, the wind decreases and the sand naturally falls.

Moreover, not only the whole north of China is a plain, but China is still a plain further north, unlike the mountains in the south of China. When the wind blows, it is immediately dispersed by the venting force, so the wind in the north is basically not solved. What we can solve is to try not to let the sand rise into the air.

Second, the wind in the north is not just this year.

It is easy for us to think that only this year will there be dust. In fact, there is dust every year. We have sandstorms all year round in Chifeng, but it is much better now. Because many trees have been planted, the amount of sand in the wind is not so great. When I didn't realize planting trees, the sand in the wind hurt especially when it hit my face.

Although we can't get rid of the wind, we can solve the sediment concentration in the wind. This is all because of the role of trees. We must plant all kinds of trees in the future. This is no small matter. Without trees and grass, the northern part of China would be a desert.
