Wear cotton-padded jacket in the morning and gauze in the afternoon, and eat watermelon around the stove. Why is the temperature difference so big in Xinjiang?

Although the spring and autumn seasons in Turpan are very short, the temperature difference between day and night in Turpan is particularly large. It is precisely because of this that there is a saying that "wear cotton-padded jacket early and yarn at noon, and eat watermelon around the stove".

Seeing this, I think everyone will ask, also in Xinjiang, why is the temperature in Turpan as high as 40℃, while Zhaosu County in Yili is surrounded by snow-capped mountains? Is this the "two worlds of ice and fire" in folklore?

As we all know, Turpan has an average of 152 days in summer, and the weather above 35℃ is more than 90 days all year round. Although it is very hot during the day, it is often rainy and snowy at night, which means that you have to experience the temperature difference span from wearing short sleeves to changing cotton-padded clothes in one day.

Geographically, Zhaosu County is located in the upper reaches of Yili River and belongs to an intermountain basin surrounded by mountains. Although it is sunny in July, there are continuous snow-capped mountains not far from the county seat. Sometimes it's really weird. Although it is surrounded by snow-capped mountains, you can see endless rape blossoms in the local area. This is the case in Xinjiang where snow-capped mountains and basins intersect. The mountains here are more than 40 degrees, and dozens of kilometers to the north are snow-capped mountains.

Xinjiang can welcome snowfall in August, and the temperature difference will widen to more than 30 degrees overnight. In fact, this is not as complicated as everyone thinks, because there is temperature exposure during the day, so the temperature will rise quickly and release heat on the surface at night. What's more, Xinjiang is far from the ocean, but the thermal storage capacity of the desert is not as strong as that of the ocean, which is doomed to widen the temperature difference between day and night.
