Where is the most sandstorm in China?

Keping (79.0 east longitude, 40.5 north latitude) is located in Aksu area in the west of Xinjiang Uygur Autonomous Region, with an average annual sandstorm days of 38.8 days, with the maximum of 53 days in a year and the minimum of 26 days in a juvenile, which is the place with the largest sandstorm days in China.

Keping is located in the western margin of Tarim Basin. Tarim basin is located in the hinterland of Eurasia, far from the ocean, blocked by high mountains, difficult to reach the sea breeze and dry climate.

The center of Tarim Basin is 330,000 square kilometers of Taklimakan Desert. In spring and summer, the temperature in Taklimakan desert rises sharply, and it is easy to form thermal depression in the basin. The low-level airflow in the basin converges and rises strongly, and the cold air around the basin quickly supplements, forming a fierce wind, blowing up the dust in the desert and making the air very turbid. Therefore, the sandstorms in Keping occur most frequently in spring and summer every year, especially in June, with an average of 7.9 days.

In Keping county, it is mainly mountainous, but the east is plain. In autumn and winter, strong cold air often invades from the eastern plain of Keping, causing windy weather, and the wind blows up dust and sandstorms. Because Keping has windy weather all year round and is close to the desert, it has become the place where sandstorms occur most frequently in China.
