Are there sandstorms in Mongolia?

There are sandstorms in Mongolia. Mongolia is located in the mainland, with arid climate, scarce vegetation and abundant sand sources. Near the wind source, there are many windy days and sandstorms.

Sandstorm refers to the weather phenomenon that strong winds blow up dust on the ground, making the air very turbid and the horizontal visibility less than 1km.

Sandstorm weather mainly occurs in winter and spring. This is 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 very weak. When there is a strong wind blowing, a lot of dust will be involved in the air, forming sandstorm weather.

The formation of sandstorms requires three conditions:

One is the dust on the ground. It is the material basis for the formation of sandstorms.

The second is the strong wind. This is the dynamic basis for the formation of sandstorms and the dynamic guarantee for the long-distance transportation of sandstorms.

Third, the air state is unstable. This is an important local thermal condition. Sandstorms often occur in the afternoon and evening, which shows the importance of local thermal conditions.

Mongolia is located in the Mongolian Plateau of Central Asia, bordering China on the east, south and west, and Siberia on the north. The terrain of Mongolia gradually decreases from west to east, with the highest elevation of 4,653 meters (Nairamdar Peak) and the lowest elevation of 553 meters (Huhehu Lake), with an average elevation of 1.580 meters. The mountainous area is 777,000 square kilometers, accounting for half of the total area; The Gobi Desert covers an area of 400,000 square kilometers, accounting for a quarter of the total area; Lake area 1.6 million square kilometers, accounting for 1% of the total area.

Most parts of Mongolia belong to continental temperate grassland climate, with obvious seasonal changes, long winters and frequent snowstorms. Summer is short, and the temperature difference between day and night is large; Spring and autumn are short. More than half of the year is shrouded in continental high pressure. It is the most powerful Mongolian high pressure center in the world and one of the sources of winter "cold wave" in Asian monsoon climate zone.
