What's the weather like in Mu Us Sandy Land in a year?

The elevation of Mu Us sandy land is mostly at1100 ~1300m, slightly higher in the northwest, reaching 1400 ~ 1500m, and it can reach 1600m in some areas. The valley in the southeast is as low as 950 meters. Mu Us Sandy Land is mainly located in the lake alluvial plain depression between Ordos Plateau and Loess Plateau. Beams exposed at the periphery of the sand area and extending into the sand area are mainly Cretaceous red and gray sandstone, and the rock strata are basically horizontal, and most of the beams have flat top surfaces. Various Quaternary sediments are obviously sandy, and loose sand layers are transported by the wind to form flowing quicksand. Plain high beach land (including plain watershed land and Liangbian high beach land) is mainly distributed in Holocene Pliocene lacustrine alluvium. The average annual temperature in the sandy area is 6.0 ~ 8.5℃, 1 month is -9.5 ~ 12℃, the average temperature in July is 22 ~ 24℃, and the annual precipitation is 250 ~ 440mm, which is concentrated in July ~ September, accounting for 60 ~ 75% of the annual precipitation, especially in August. The precipitation varies greatly from year to year, and the rainy year is 2 ~ 4 times that of the dry year. Drought and waterlogging often occur, and drought is greater than waterlogging. In summer, there are frequent storms and hail disasters, and the maximum daily precipitation can reach100 ~ 200 mm. The annual precipitation in the eastern part of the sandy land is 400 ~ 440mm, which belongs to the shallow chestnut grassland belt. The quicksand and Bala (semi-fixed and fixed dunes) are widely distributed, and the precipitation in the northwest is 250 ~ 300mm, which belongs to the brown calcareous semi-desert belt.
