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

Frequent sandstorms in the north are mainly influenced by many factors, including natural factors and human factors:

Natural factors: The natural environment is the basis for the formation of sandstorm weather, including weather conditions such as strong wind and natural geographical environment such as drought and desertification. This spring, the northern part of China was affected by La Ni? a climate events, with low humidity, abnormal atmospheric circulation and reduced frequency of desert dustfall cycle, which made sandstorms frequent.

Human factors: human activities are also a major factor in frequent sandstorms. Urbanization, deforestation, excessive land reclamation, and the increasing popularity of modern chemical agriculture and transportation have all increased the exposure of sand and caused sandstorm pollution.

External factors: Dust weather is also affected by external factors such as meteorological conditions. For example, the East Asian summer monsoon, Siberian high and other weather circulation systems have a direct impact on dust weather, as well as the Yellow Sea cold vortex and other systems.

The comprehensive effect of the above factors has led to frequent and long-lasting dusty weather in northern China this year. In view of this situation, measures such as strengthening ecological environment protection, promoting desertification control and curbing over-exploitation should be taken to reduce the occurrence of sandstorms.
