What season does the weather in Shacheng often appear?

Sandstorm weather mostly occurs in late spring and early summer, because there is little precipitation in winter and spring in arid areas, the surface is unusually dry and loose, and the wind erosion resistance is weak. When the wind blows, it will suck a lot of sand into the air, forming sandstorm weather.

After a large-scale sandstorm occurred in late winter and early spring, the dust raised by strong winds caused a lot of dust in the air, which blocked the local sunshine and even made the visibility zero. Therefore, super sandstorms are also called black storms. Sandstorm will cause great losses to people's lives, property and agriculture. Sandstorms mainly originate in desertification areas, with soft soil, dry ground and no vegetation. Once the air is unstable in a large range and the surface wind speed is high, it is easy to blow up the surface dust and enter the air to form dusty weather. Globally, sandstorms mostly occur in inland desert areas, mainly the Sahara desert in Africa, and the midwest of North America and Australia are also one of the sources of sandstorms.
