The climate of northern and southern Xinjiang

1, northern and southern Xinjiang are separated by Tianshan Mountain, which will undoubtedly affect the climate of the two places. 2. In addition, there is a large area of desert in southern Xinjiang and a large area of basin in northern Xinjiang, so the atmospheric inverse radiation in southern Xinjiang should be greater than that in northern Xinjiang. 3. The above two points affect the atmospheric circulation in the two places, so the climate is quite different. Climate difference is generally caused by many influences. Northern and southern Xinjiang belong to continental climate, with long and cold winters and short and hot summers. The climate is dry, with sufficient light and heat and little precipitation. Taking Tianshan Mountain as the boundary, there are obvious differences between northern Xinjiang and southern Xinjiang. Northern Xinjiang has a temperate continental arid and semi-arid climate, while southern Xinjiang has a warm temperate continental arid climate. The annual average temperature in northern Xinjiang is -4 ~ 9℃, the annual precipitation is above 150 ~ 200mm, and the annual frost-free period is 140 ~ 185 days. The annual average temperature in southern Xinjiang is 7 ~ 14℃, the annual precipitation is 25 ~ 100 mm, and the annual frost-free period is 180 ~ 220 days.
