Gobi Desert




The Gobi is the largest desert region in Asia. It covers parts of northern and northwestern China, and of southern Mongolia. The desert basins of the Gobi are bounded by the Altai Mountains and the grasslands and steppes of Mongolia on the north, by the Hexi Corridor and Tibetan Plateau to the southwest, and by the North China Plain to the southeast. The Gobi is made up of several distinct ecological and geographic regions based on variations in climate and topography. This desert is the fifth largest in the world.


The Gobi is most notable in history as part of the great Mongol Empire, and as the location of several important cities along the Silk Road.


The Gobi is a rain shadow desert formed by the Himalaya range blocking rain-carrying clouds from reaching the Gobi.


The Gobi desert, one of the world's great deserts, covers much of the southern part of Mongolia. Unlike the Sahara there are few sand dunes in the Gobi; rather you'll find large barren expenses of gravel plains and rocky outcrops. The climate here is extreme. Temperatures reach over 40°C in summer, and -40 in winter. Precipitation averages less than 100 mm per year, while some areas only get rain once every two or three years. Strong winds up to 140 km/h make travel dangerous in spring and fall. Great Gobi National Park is one of the largest World Biospheres, with an area larger than Switzerland. It contains the last remaining wild Bacterian (two-humped) camels, wild ass, and a small population of Gobi bears, the only desert-inhabiting bear.
