Which city has the most serious sandstorm?

The cities with serious sandstorms are around Tarim Basin, Turpan-Hami Basin passes through Hexi Corridor, Ningxia Plain to northern Shaanxi, Alashan Plateau in Inner Mongolia, Hetao Plain and Ordos Plateau. North China, Chifeng and Zhangjiakou directly affect the security of the capital Beijing.

the center of Tarim basin is 33, square kilometers of Taklimakan desert. In spring and summer, the temperature of Taklimakan desert is rising sharply, and it is easy to form a thermal depression in the basin. The low-level airflow in the basin converges strongly and rises, and the cold air around the basin is rapidly replenished, which forms a fierce gale, which blows up dust and sand in the desert and makes the air very turbid. Therefore, in spring and summer every year, it is the time when sandstorms occur most in Keping, especially in June, with an average of 7.9 days.

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