Why is there more dusty weather in Beijing recently than in previous years?

There may be several reasons why there is more dusty weather in Beijing recently than in previous years. Here are some possible reasons:

Drought and increased wind in the north: dry weather and increased wind will lead to more soil erosion and dust, leading to more dusty weather.

Desertification trend: In northern China, including Inner Mongolia, Gansu, Ningxia and other provinces, many areas are experiencing desertification. This means that the vegetation coverage on land becomes worse or disappears, which leads to more frequent droughts, sandstorms and dusty weather.

International influence: If the sandstorm weather system in other countries moves to Beijing, it will lead to more sandstorms.

It should be noted that these are only the reasons that may lead to the increase of sandstorm weather in Beijing, and there is no guarantee that these reasons are correct, and no single reason can be completely explained.
