Why are there many aeolian landforms in Tarim basin and wind erosion landforms in Qaidam basin?

Tarim basin is very closed, with Tianshan Mountain extending from east to west in the north and Pamir Plateau in the west. Due to the steep terrain, the wind is relatively small, but the wind is relatively strong in the east, and there are many aeolian landforms, including sand dunes and sand ridges, which are mostly distributed in the Taklimakan desert. In fact, there are many wind erosion landforms here, typical of which is Lop Nur in Tarim Basin, which is called "Ya Dan" in Uygur language, which means steep walls.

The wind erosion landform in Qaidam Basin is world-famous, which is caused by weathering and wind. Qaidam basin belongs to plateau continental climate, with drought as the main feature and drastic temperature changes. The annual absolute temperature difference can reach more than 60℃, and the daily temperature difference is often around 30℃, so the rock weathering is serious. At the same time, the Qaidam basin also belongs to the desert area where strong winds prevail. In the spring and autumn rainy season, strong winds prevailed and were blocked by Kunlun Mountain in the west, and the wind direction changed. The wind rubs the rocks near the ground with debris and sand grains and gradually erodes them, forming various wind erosion landforms such as wind erosion mushrooms, wind erosion depressions and wind erosion castles.

In fact, deserts are widely distributed in the Qaidam basin, so there are also aeolian landforms.
