Weather in mountain basin

Tianshan Mountain is located in the hinterland of Eurasia, with an average elevation of about 4000 meters. It starts from the Gobi of Xingxingxia in Hami, Xinjiang, China in the east and reaches the Kizilekum Desert in Uzbekistan in the west. From east to west, it spans China, Kazakstan, Kyrgyzstan and Uzbekistan, and stretches for about 1 1,760 kilometers in Xinjiang, China. ?

The Tianshan Mountains in Xinjiang run through the whole territory of Xinjiang, passing through Kashgar, Kizilsu Kirgiz Autonomous Prefecture, Aksu region, Bayinguoleng Mongolian Autonomous Prefecture, Turpan City, Hami City, Yili Kazakh Autonomous Prefecture in northern Xinjiang, Bortala Mongolian Autonomous Prefecture, Shihezi City, Changji Hui Autonomous Prefecture, Urumqi City and other cities.

Tianshan Mountain is the natural geographical boundary between Junggar Basin and Tarim Basin, surrounded by Taklimakan Desert and Gurbantunggut Desert in the north and south, which is a unique symbol of Xinjiang's geography.

trait

Tianshan Mountain is the largest independent zonal mountain system in the world, the farthest mountain system from the ocean in the world and the largest mountain system in the global arid area.

Tianshan Mountain belongs to a relatively young mountain system, which was formed about two or three million years ago. About120-200 million years ago. The geological evolution after the formation of Tianshan Mountains can be divided into syncollision-post-collision tectonic magmatism stage from the end of Carboniferous to the beginning of Permian, mantle-derived magmatism and crust-mantle interaction stage from early to middle Permian, and intracontinental evolution stage since late Permian.

Climatic characteristics

1, Tianshan Mountain is the only large mountain range in the world sandwiched by a huge desert. With its profound inland geographical location, temperate continental arid climate, landscape pattern of mountains and basins, numerous glacial rivers, wonderful natural scenery, special biota and ecological processes, it has become the most typical representative of large-scale mountain ecosystems in temperate arid regions around the world.

2. The climate of Tianshan Mountain is obviously divided into cold and warm seasons in the middle of a year. How sunny it is in the cold season. The mountains, basins and valleys below 3000 meters are covered with deep snow, foggy and frosty. In warm season (summer), it is rainy and snowy above 3000 meters above sea level. The climate is cool below 3000 meters.

3. The annual precipitation in Tianshan Mountain area gradually decreases from west to east on the same hillside; The windward slope (north slope) in mountainous area is larger than the leeward slope (south slope); There are fewer basins or valleys in mountainous areas than in peripheral mountainous areas.
