Why does Urumqi become a "foggy city" in winter?

Speaking of beautiful Xinjiang and beautiful Urumqi, everyone thinks that winter should be like this.

However, the reality is cruel. Urumqi, which we have seen every day recently, is almost like this!

This has a lot to do with the geographical environment of Urumqi! Urumqi is located in the hinterland of Eurasia, at the northern foot of Tianshan Mountain, in the middle of the southern margin of Junggar Basin, with a length of about 160km from east to west and a width of about 100km from north to south. It belongs to temperate continental climate.

In winter (65438+February to February of the following year), the foggy weather in Urumqi is more distributed in the north, but less in the south and south.

After the cold air sinks, it forms a strong inversion layer, which has poor air mobility and is easy to fog. Compared with Tianshan area, Midong area has more foggy days and longer fog duration.

In addition, it is easy to blow the north wind in winter in Midong District, and the dense fog spreads from north to south. Friends who drive will definitely think that the fog in the north of Suzhou Road overpass is generally larger, and the fog in the south is slightly better.

The inversion layer makes the fog cover Urumqi like a pot cover. Will you stay for a long time? I can only hope that a heavy snow will break the stable inversion layer and disperse the fog!
