Main factors leading to cold in the south and hot in the north of Xinjiang

The influence of land and sea location

Precipitation: At the northern foot of Altai Mountain in northern Xinjiang, affected by Siberian-Mongolian high in winter, cold air from the Arctic Ocean will bring a small amount of water vapor and form precipitation at the foot of Altai Mountain; In the northern Tianshan Mountains, the westerly wind from the Atlantic Ocean, under the influence of the southward shift of climate zone, carries a small amount of water vapor from Alashankou into China every winter, forming precipitation at the foot of Tianshan Mountains; The Taklimakan Desert in southern Xinjiang is surrounded by Kunlun Mountain, Tianshan Mountain, Pamir Plateau and Qilian Mountain. And it is deep inland. Water vapor in the Pacific Ocean, Atlantic Ocean, Indian Ocean and Arctic Ocean is blocked, making it difficult to form precipitation. Temperature: fundamentally speaking, it is the difference of latitude; Topographically, precipitation is easy to form in the north, so the temperature difference between winter and summer is small and the temperature is low, and the weather in the south is dry, so the temperature difference between winter and summer is large and the temperature is high.
