How is the dusty weather that seriously harms people's health formed?

Sandstorm weather refers to a weather phenomenon that strong winds bring dust, sand and other turbid substances on the ground into the air, which reduces the visibility of the air. Due to the dry climate in northern China, dusty weather often occurs in northern China, especially in spring. When dusty weather happens, it will affect people's normal travel and increase the probability of traffic accidents. At the same time, it will increase the probability of the spread of some infectious diseases and cause harm to people's respiratory system. So how did this harmful weather form? What preventive measures are there? The fundamental cause of sandstorm weather is land desertification, and the most fundamental way to prevent this weather is to plant trees. In this weather, we should pay attention to the protection of respiratory organs and travel cautiously.

1. Since the dusty weather is the reason, there will definitely be dust. The dust mainly comes from dry sand and gravel on the ground. When the wind is strong enough, it will blow up the sand and gravel on the ground, benefiting from the increase of wind, strong convective weather and narrow terrain, which will lead to more serious sandstorm weather. Therefore, sand and gravel are the material foundation, strong wind is the power foundation, and strong convective weather, topography and temperature rise are the catalysts of sand and dust weather.

Second, how to do a good job in environmental governance and personal protection? So how can we correct this weather? According to the above analysis, it is enough to reduce both the material foundation and the dynamic foundation by one. It is unrealistic to reduce the wind, so it is enough to reduce the sand content on the ground. The most effective way is to plant trees. For example, Saihanba in northern China is a good example. Afforestation can consolidate soil and slow down the rate of land desertification. If such weather really occurs, then we should travel carefully and take protective measures such as wearing headscarves and masks. So that when this weather happens, we can cope.

The above is the analysis of dusty weather, and you are welcome to add it.
