Why is the dust so frequent this year?

Dust weather is becoming more and more frequent this year. The main reasons are: meteorological factors, natural factors and human factors.

1, meteorological factors

Less rainfall, higher temperature and dry atmosphere in Northeast China, North China and Northwest China this spring are all necessary conditions for sandstorm weather. In addition, the wind speed in northwest China is relatively high this year, which also provides conditions for the formation of sandstorm weather.

2. Natural factors

Meteorological factors are one of the main factors leading to frequent sandstorms. Less rainfall, higher temperature and dry atmosphere in Northeast China, North China and Northwest China this spring are all necessary conditions for sandstorm weather. In addition, the wind speed in northwest China is relatively high this year, which also provides conditions for the formation of sandstorm weather.

3. Human factors

With the acceleration of urbanization, great changes have taken place in people's lifestyles and modes of production. Unreasonable development and utilization of land, over-exploitation, over-grazing and over-reclamation will all lead to land desertification, thus aggravating the frequent occurrence of sandstorms. In addition, the process of industrialization has also led to the discharge of a large number of dust and pollutants, which will have an impact on the formation and development of dusty weather.

Sandstorm control measures:

1. Environmental control is the key measure to prevent and control sandstorms. Strengthen soil and water conservation, vegetation restoration and desertification control. Reduce the area of bare land, improve the ability of land conservation, reduce land erosion and curb the occurrence of sandstorms from the source.

2. It is of great significance to grasp the occurrence and development trend of sandstorm in time for taking timely measures to prevent disaster expansion and loss increase. Strengthen the construction of sandstorm monitoring system, improve the coverage and accuracy of monitoring and early warning, so that early warning information can be conveyed to the public in time and provide necessary support for taking measures.

3. Strengthen publicity and education for the public, improve public awareness and understanding of sandstorms, enhance public awareness of prevention, and reduce the time and frequency of public exposure to sandstorms, thus reducing the harm of sandstorms.
