Classes in Baotou, Inner Mongolia were suspended due to dust. What is the reason for the dusty weather?

First, sandstorms caused by changes in natural conditions need three conditions besides sandstorms, strong winds and poor air quality. Under the action of these three conditions, sandstorms will occur. Therefore, when the natural conditions change and the three conditions needed for sandstorm just gather, sandstorm occurs.

Under normal circumstances, when the weather is dry in recent days, the weather is getting warmer and warmer, the possibility of sandstorms will increase. In this context, it is likely to form a strong wind environment, coupled with the dry climate leading to an increase in sand blowing, making it easier to form sandstorms in open areas.

Second: man-made destruction of nature has a lot to do with human destruction of nature. Because desert areas are more prone to sandstorms, there are no plants to stop them. When the wind blows, sand will be rolled up and sandstorms will appear. If the green area of nature is high, trees are not cut down, and there is no excessive reclamation, then even if there is a sandstorm, the vegetation on the ground can stop it.

But now the sandstorm is so serious because human beings destroy nature. In order to use wood, people will cut down excessively, which will destroy the vegetation in many places, while overgrazing will also destroy the vegetation on the ground and make the land gradually desert. After serious desertification, sandstorms will appear more frequently. When a sandstorm occurs, there are no plants nearby to stop it, so there will be more and more serious sandstorm weather.

Third, the gradual increase in temperature is related to the release of too much carbon dioxide by human beings. It is precisely because of the increase in the amount of carbon dioxide released that there is a hole in the atmosphere, so the temperature on the ground has also started to rise, the natural environment has been seriously damaged, and the climatic conditions have begun to become very different. In winter, the temperature of 20 degrees appears in both the Antarctic and the Arctic, which makes the glaciers melt and has a great impact on nature. However, when winter and spring alternate, due to the rising temperature, strong winds are more likely to occur, and the climate is dry, which creates conditions for sandstorms. Especially in desert areas, under the blessing of these two conditions, sandstorms occur from time to time.
