Gobi desert Mongolia
Gobi Desert is a large 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 Taklamakan Desert to the west, by the Hexi Corridor and Tibetan Plateau to the southwest, and by the North China Plain to the southeast. The Gobi is 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 Tibetan Plateau blocking precipitation from the Indian Ocean reaching the Gobi territory.
The Gobi measures over 1,600 km (1,000 mi) from southwest to northeast and 800 km (500 mi) from north to south. The desert is widest in the west, along the line joining the Lake Bosten and the Lop Nor (87°–89° east). It occupies an arc of land 1,295,000 km2 (500,000 sq mi) in area as of 2007; it is the fifth-largest desert in the world and Asia’s second largest. Much of the Gobi is not sandy but has exposed bare rock.
In its broadest definition, the Gobi includes the long stretch of desert extending from the foot of the Pamirs (77° east) to the Greater Khingan Mountains, 116°-118° east, on the border of Manchuria; and from the foothills of the Altay, Sayan, and Yablonoi mountain ranges on the north to the Kunlun, Altyn-Tagh, and Qilian mountain ranges, which form the northern edges of the Tibetan Plateau, on the south.
Archeologists and paleontologists have done excavations in the Nemegt Basin in the northwestern part of the Gobi Desert (in Mongolia), which is noted for its fossil treasures, including early mammals, dinosaur eggs, and prehistoric stone implements, some 100,000 years old
The Gobi is overall a cold desert, with frost and occasionally snow occurring on its dunes. Besides being quite far north, it is also located on a plateau roughly 910–1,520 metres (2,990–4,990 ft) above sea level, which contributes to its low temperatures. An average of approximately 194 millimetres (7.6 in) 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 −40 °C (−40 °F) in winter to 45 °C (113 °F) in summer
Although the southeast monsoons reach the southeast parts of the Gobi, the area throughout this region is generally characterized by extreme dryness, especially during the winter, when the Siberian anticyclone is at its strongest. The southern and central parts of the Gobi Desert have variable plant growth due to this monsoon activity. The more northern areas of the Gobi are very cold and dry, making it unable to support much plant growth; this cold and dry weather is attributed to Siberian-Mongolian high pressure cells.Hence, the icy sandstorms and snowstorms of spring and early summer plus early January (winter).
Mongolian Gobi desert
Mongolian Gobi is known for its dunes, mountains and rare animals such as snow leopards and Bactrian camels. In the Gobi Gurvansaikhan National Park, the Khongoryn Els sand dunes are said to sing when the wind blows. The park also features the deep ice field of Yolyn Am canyon. Dinosaur fossils have been found at the red “Flaming Cliffs” of Bayanzag.
The Mongolian government established the Great Gobi National Park in 1975 and the UNESCO designated as the Great Gobi as the fourth largest Biosphere Reserve in the world in 1991. Mongolians consider that there are 33 different Gobi , where sandy desert occupies only 3 percent of the total territory. The area is often imagined as a lifeless desert like in many other parts of the world. Gobi Desert is a land of dinosaurs and it is the home for camel breeders rich with wildlife and vegetation. Dinosaur skeletons and their petrified eggs have been preserved here to the present day. Wild asses, camels, snow leopards, mountain sheep and gazelles flourish here, as do different types of flora.
