Meteorologists or historians, who knows what a 9355 sandstorm is

I'm more sure it was the sandstorm on May 5, 1993, not a term. Click on the specifics.

Stop creating conceptual hype, and stop wasting your time on this.

Because of the convection of hot and cold air, and then the wind is generated, and when the wind reaches a certain level, there will be a sandstorm. The only way to deal with sandstorms is to increase the number of forest protection belts and increase the area of soil consolidation.

Isn't it a sandstorm when the wind blows the sand through? And it is large-scale, mainly caused by desertification.

From a global perspective, sandstorms mostly occur in inland desert areas, mainly in the Sahara Desert in Africa, and the central and western parts of North America and Australia are also one of the sources of sandstorms.

Due to the unique geographical environment, the northwest region of China is also an area where sandstorms frequently occur, and the main sources are the Gurbantunggut Desert, the Taklamakan Desert, the Badain Jaran Desert, the Tengger Desert, the Ulan Buhe Desert and the Mu Us Desert.

Favorable weather conditions that produce high winds or strong winds, favorable distribution of sand and dust sources, and favorable air instability conditions are sandstorms or strong sandstorms on the Gobi Desert.

The main reason for this. Strong wind is the driving force of sandstorms, and the sources of sand and dust are the material basis of sandstorms, and unstable thermal conditions are conducive to the increase of wind and the development of strong convection, so as to entrain more sand and dust and roll higher.

From an ecology that has been destroyed by humans.

Sand and dust storm is a disastrous weather phenomenon in which wind and sand interact, and its formation is inextricably related to the global warming effect, El Niño phenomenon, deforestation, vegetation destruction, species extinction, climate anomalies and other factors. Among them, the overexploitation of natural resources, excessive deforestation, and over-reclamation of land caused by population expansion are the main reasons for the frequent occurrence of sandstorms.

The trend is to become more frequent.

The main reasons are the desertification of the land, the reduction of soil moisture content, the destruction of a large number of vegetation, the desertification of the soil caused by acid rain caused by air pollution, and the formation of sandstorms with the help of wind energy.

Only by caring for the environment, planting grasses to conserve water, and preventing soil desertification, can the occurrence of sandstorms be stopped.

Soil wind erosion is the primary link in the occurrence and development of sandstorms. Wind is the most direct driving force of soil, and soil moisture content is also an important cause of soil wind erosion.

Plant measures can prevent sandstorms. Plants can disperse a certain amount of wind momentum on the ground, reducing the transfer between air currents and sand and dust; Stop the movement of soil and dust.

Of course, everyone doesn't care about the environment Multi-value tree (I may have written it wrong, hehe).

Or take care of the environment.

If you have to talk about the first sandstorm in Beijing.

That was when Beijing became Beijing.

Sandstorms are a natural phenomenon in North China that carries dust from the Loess Plateau and the Mongolian Plateau under the influence of the Siberian cold wave. It existed before humans even existed. The Loess Plateau was formed by the accumulation of dust by air currents.
