Why is there frequent dusty weather in the north this year?

Global warming, human activities and natural factors.

Affected by cold air, the strongest dust weather process has invaded the north this year.

Why is there frequent dusty weather in the north this year? The reasons are as follows: 1, global warming. With global warming, the frequency and intensity of extreme weather events are increasing. This year, the winter climate in the northern region is relatively dry, with less precipitation, which provides sufficient material basis for the occurrence of sandstorm weather. At the same time, global warming also leads to abnormal atmospheric circulation, weakened cold air activity and active warm and humid air flow, which provides favorable conditions for sandstorm weather.

2. The influence of human activities. In recent years, the acceleration of human activities, especially the urbanization process, has reduced the coverage area of forests, grasslands and other vegetation, intensified land desertification, and provided more possibilities for the occurrence of sandstorms. In addition, the overexploitation of land resources and the destruction of vegetation in some areas will also lead to sandstorms.

3. Natural factors. Sandstorm weather may also be affected by natural factors, such as earthquakes, volcanic eruptions and other geological activities, resulting in a lot of dust and volcanic ash and other substances, thus forming sandstorm weather.
