Windy weather and dusty weather

What do you think is the reason for frequent sandstorms and strong winds?

Why are sandstorms and windy weather frequent this year? First of all, we need to know why there is windy weather and what causes the wind. Why is there dusty weather after secretion?

Wind power generation is because the temperature is different in different areas, and the temperature affects the density of air. When the temperature is different, the density in different areas will also have a certain gap. Affected by physics, high-density areas will generate electricity to low-density spaces, thus generating wind. However, after the gale, if the vegetation coverage is low and the wind passes through more floating soil on the ground, the dry soil and rotten soil on the surface affected by the wind will be caught in the air, resulting in dusty weather. Generally speaking, strong wind and dust are the necessary factors to produce dusty weather.

China is located in the southeast of the Eurasian plate. Northwest China has high altitude and low temperature, so the air pressure is high. The southeast is the largest ocean and Pacific Ocean in the world. Affected by seawater, the temperature in the Pacific Ocean is relatively high all the year round, so the air pressure is relatively low. There will be more windy weather in our country. This year, due to the scarcity of precipitation in Mongolia in the northwest of China, the temperature is on the high side. Under the influence of Mongolian cyclone wind, the ground often melts in cold air activities. It is easy to lift the floating soil on the ground. Follow the cold air into our country from the south.

The northwest of China is located in the mainland, with dry climate and less vegetation. Serious soil erosion and desertification on the ground add a lot of dust to the cold air in the south. It will cause the change from strong wind to dusty weather.

Generally speaking, sandstorms and windy weather are partly due to the climate change of the earth. Part of the reason is that there is less vegetation coverage, serious desertification and serious soil erosion in the western region of China. Added a lot of floating soil to the cold air heading south. If the vegetation cover area in northwest China is wide. Then the vast vegetation forest will not only protect the soil from strong winds, but also reduce the frequency and speed of strong winds.
