Why does Urumqi turn into "Wrumqi" in winter?
When it comes to beautiful Xinjiang and beautiful Urumqi, everyone thinks that winter should be like this
However, the reality is cruel. Recently, the Urumqi we see every day is almost like this. Son! /faf2b2119313b07e320d06c107d7912396dd8c43?x-bce-process=image/resize,m_lfit,w_450,h_600,limit_1/quality,q_85
Why does Urumqi become Wulumuqi in winter? This has a lot to do with the geographical environment where Urumqi is located! Urumqi is located in the hinterland of Eurasia, at the northern foot of the Tianshan Mountains and in the middle section of the southern edge of the Junggar Basin. It is about 160km long from east to west and 100km wide from north to south. It has a temperate continental climate. /3812b31bb051f8191ba25583d1b44aed2f73e770?x-bce-process=image/resize,m_lfit,w_450,h_600,limit_1/quality,q_85
Affected by the terrain, Urumqi has heavy fog in winter (December to February) The distribution is more in the north of the city and less in the southern suburbs and Nanshan. Among them, the average is 25 days in Midong District, 20 days in Tianshan District, 5 days in Nanshan Xiaoquzi, and less than 2 days in Dabancheng. In winter, there are often heavy fog in the north of the city and high sunshine in the southern suburbs and south mountains. photo phenomenon. /6a63f6246b600c335c958801114c510fd8f9a10f?x-bce-process=image/resize,m_lfit,w_450,h_600,limit_1/quality,q_85
Since Dabancheng is located at the wind outlet, the northwest wind prevails in winter, which is not conducive to the accumulation of water vapor, making it difficult to Heavy fog forms. /5ab5c9ea15ce36d33ee8d5f931f33a87e850b10f?x-bce-process=image/resize,m_lfit,w_450,h_600,limit_1/quality,q_85
The average altitude of the southern suburbs and Nanshan is above 1,500 meters, which is at the top of the inversion layer and the air flows It has good performance and is not conducive to the formation of heavy fog. /342ac65c103853430f23d1e89813b07ecb80880f?x-bce-process=image/resize,m_lfit,w_450,h_600,limit_1/quality,q_85
Midong District is low-lying, with an altitude of 600 meters. It is more than 300 meters different from Tianshan District. The cold air After sinking, a strong inversion layer is formed, the air mobility is poor, and heavy fog is easy to gather. Compared with Tianshan District, Midong District has more foggy days and the fog lasts longer.
Furthermore, in Midong District, north winds tend to blow in winter, and thick fog spreads from north to south. Driving friends will definitely feel that the fog is generally heavier north of the Suzhou Road overpass, and slightly better south of it. /f9dcd100baa1cd11252b24e9b212c8fcc2ce2d5d?x-bce-process=image/resize,m_lfit,w_450,h_600,limit_1/quality,q_85
The basin terrain of Urumqi, surrounded by mountains on three sides, also prevents the condensation nuclei of inhalable particles from forming mist. It disperses easily, so heavy fog occurs frequently.
The inversion layer makes the fog hang over Urumqi like a pot lid, unwilling to leave for a long time? We can only hope for a heavy snowfall to break the stable inversion layer and disperse the fog! /0d338744ebf81a4c8fb5ba00dc2a6059242da670?x-bce-process=image/resize,m_lfit,w_450,h_600,limit_1/quality,q_85
