This is our prediction. And there may be dusty weather in mid-March and mid-late April. Please pay attention to the weather forecast near the meteorological department.

What role does the Three North Shelterbelt play in preventing sandstorm weather?

It should be good. From the perspective of shelter forest, it is beneficial to reduce the impact of dusty weather on people. For example, the movement of dust through the atmosphere abroad has a path to the north and south. Dust is transported and settled at the same time. If there is our shelter forest, on the one hand, it will reduce the wind speed, on the other hand, it will play a blocking role, reduce the concentration of atmospheric dust, and its impact on the future will also be reduced. So we should plant more trees to protect our environment. Because ecological environment is a very important condition for the formation of sandstorm weather.

What advanced methods are there to prevent and control sandstorms in the world, and what practices are worth learning from?

Sandstorm is not a unique weather phenomenon in China. There are four areas prone to sandstorms in the world. China is a part of sandstorm-prone areas in Central Asia, and foreign countries are also facing the problem of how to prevent sandstorms. What we should learn is to improve everyone's awareness of environmental protection. We know that foreign countries have a high awareness of environmental protection. On the one hand, we should raise people's awareness of environmental protection. On the other hand, we should hope that everyone will plant more trees, care for our forests and grasslands and reduce the exposed land area. This is the most direct method.
