The Nam Co (also Namtsho or Namtso ; Tibetan གནམ་ མཚོ་ Wylie gnam mtsho , Chinese 納木錯 / 纳木错 , Pinyin Nàmù Cuò ; Mongolian Tengrinor "sky lake ") is a salt lake in the Tibet Autonomous Region of the People's Republic of China .
It is located at the northern foot of the Nyainqêntanglha Mountains at an altitude of 4718 m on the border between the Damxung ( 'dam gzhung ; Chinese 当 雄 , Pinyin Dāngxióng ) and Baingoin ( dpal mgon ; Chinese 班 戈 , Pinyin Bāngē ) and has an area of over 1967 square kilometers after the Qinghai Lake (Kokonor) the second largest salt lake in China. Its extension from east to west is over 70 kilometers, from north to south over 30 kilometers. According to recent studies, its maximum depth is 125 m and about 50% of the lake is more than 90 m deep. Tashi Dor forms a peninsula of the lake .
climate
The weather at Nam Co is changeable and characterized by severe weather changes. About 90% of precipitation falls in summer, usually as snow or hail. Violent thunderstorms with heavy snowfall can occur even in August. Temperatures fluctuate between -16 ° C in winter, with temperatures dropping as low as -40 ° C, and around 9 ° C in summer, but temperatures below 0 ° C are also possible in July and August, albeit rarely. Due to the altitude and the resulting cold climate, the lake freezes over completely in December, the up to 30 cm thick layer of ice remains until the end of March. Ice floes can still drift on the lake well into July, but it is ice-free in summer.
In the late Pleistocene , the Nam Co and the Serling Tsho formed a lake with an area of 28,900 square kilometers.
