Gobi Desert it is also located on a plateau roughly above sea level, which contributes to its low temperatures. An average of approximately of rain falls annually in the Gobi. Additional moisture reaches parts of the Gobi in winter as snow is blown by the wind from the Siberian Steppes. These winds may cause the Gobi to reach in winter to in summer. However, the climate of the Gobi is one of great extremes, combined with rapid changes of temperature of as much as . These can occur not only seasonally but within 24 hours. In southern Mongolia, the temperature has been
Gobi Desert been the bottom of a former lake, but is now nearly a dry salt-basin. The surface configuration is in fact markedly similar to that which occurs in the inter-mount latitudinal valleys of the Kunlun Mountains. The hydrography of the Ghashiun-Gobi and the Kuruk-tagh is determined by these chequered arrangements of the latitudinal valleys. Most of the principal streams, instead of flowing straight down these valleys, cross them diagonally and only turn west after they have cut their way through one or more of the transverse barrier ranges. To the highest range on the great swelling Grumm-Grzhimailo gives the name of
