Da Qaidam is a county-level administrative zone in Haixi Prefecture in northwestern Qinghai province, China. It borders Gansu province to the north.

Etymology

File:NJ-46 Ko-erh-mu.jpg (1975)]]

Da Qaidam is a combination of the Hanyu Pinyin romanization of the Mandarin pronunciation of {{lang|zh|{{linktext|大}}}} (dà), the Chinese word meaning "big" or "greater", and the Zangwen Pinyin romanization of the Tibetan name {{nowrap|{{bo-textonly|{{linktext|ཚྭ}}་{{linktext|འདམ}}}}}} (qaidam), meaning "salt marsh" and referencing the surrounding Qaidam Basin. The Mandarin pinyin romanization of the Chinese transcription of Qaidam is "Cháidàn".

Geography and climate

Da Qaidam borders Delingha to the east, Lenghu to the west, Golmud across the Qarhan Playa to the south, and Jiuquan (Gansu) to the north, and is part of the northern Qaidam Basin.

Similar to neighbouring Golmud, Da Qaidam has an arid climate (Köppen BWk), with long, cold winters, and warm summers, although due to its location further north and elevation more than {{convert|350|m|-1}} higher than Golmud, its climate is also subalpine in nature. The monthly 24-hour average temperature drops to {{convert|-13.4|°C|1}} in January and rises to {{convert|15.5|°C|0}} in July, while the annual mean is {{convert|1.88|°C|1}}. Precipitation is very low, totaling only {{convert|83|mm|2|abbr=on}} per annum, falling on 35 days, most of which are during the summer. With monthly percent possible sunshine ranging from 65% in July to 82% in October, the area receives 3,257 hours of bright sunshine annually.
