Why does Urumqi Diwopu Airport often fog?

The frequent fogging at Urumqi Diwopu Airport is related to geography and climate.

Urumqi is surrounded by mountains on three sides, and its northern part looks like a trumpet facing the Junggar Basin. Due to the barrier of the Tianshan Mountains, cold air often stays in the basin. Urumqi Diwopu Airport is located right on this trumpet, with large temperature differences and drastic changes in cold and heat. Conditions for fog formation: First, cooling, second, humidification to increase water vapor content. Due to the dual influence of geography and climate, Urumqi Diwopu Airport has a large temperature difference, which easily meets the conditions for fog formation, so it often fogs.

When the relative humidity reaches 100% when there is sufficient water vapor, gentle breeze, and stable atmosphere, the water vapor in the air will condense into fine water droplets suspended in the air, reducing visibility at ground level. This The weather phenomenon is called fog. Fog occurs more often in spring from February to April. Whenever the visibility is lower than 1 km due to the condensation of suspended water vapor in the atmosphere, meteorology calls this weather phenomenon fog.

Urumqi Diwobao International Airport is a civil airport located 16 kilometers northwest of Urumqi. It is a key city for China Southern Airlines and Hainan Airlines. It has now become one of the important hub airports in the west.
