This is a list of the largest deserts in the world by area. It includes all deserts above 50,000 km 2 (19,300 sq mi). ... Gobi Desert: Cold winter: 1,295,000 [1]
Sahara Desert – Africa's largest desert and the world's largest hot desert which covers much of North Africa comprising: Ténéré – a desert covering northeastern Niger and western Chad Sahara Desert; Tanezrouft – a desert covering northern Mali, northwestern Niger as well as central and southern Algeria, at the west of the Hoggar Mountains
Eolian processes are major factors in shaping desert landscapes. Polar deserts (also seen as "cold deserts") have similar features, except the main form of precipitation is snow rather than rain. Antarctica is the world's largest cold desert (composed of about 98% thick continental ice sheet and 2% barren rock).
The Ladakh region and the city of Leh in the Great Himalayas in India also have a cold desert climate. In North America, the cold desert climate occurs in the drier parts of the Great Basin Desert and the Bighorn Basin in Big Horn and Washakie County in Wyoming. The Hautes Plaines, located in the northeastern section of Morocco and in Algeria ...
The Patagonian Desert is the largest desert south of the 40° parallel and is a large cold winter desert, where the temperature rarely exceeds 12 °C and averages just 3 °C. The region experiences about seven months of winter and five months of summer. Frost is not uncommon in the desert but, due to the very dry condition year round, snow is rare.
The Gobi Desert (Mongolian: Говь, ᠭᠣᠪᠢ, / ˈ ɡ oʊ b i /; Chinese: 戈壁; pinyin: gēbì) is a large, cold desert and grassland region located in northern China and southern Mongolia. It is the sixth largest desert in the world .
The harsh climate of most desert regions is a major obstacle in conducting research into these ecosystems. In the environments requiring special adaptations to survive, it is often difficult or even impossible for researchers to spend extended periods of time investigating the ecology of such regions.
If the area's annual precipitation in millimeters is less than the threshold but more than half or 50% the threshold, it is classified as a BS (steppe, semi-desert, or semi-arid climate). [2] Furthermore, to delineate hot semi-arid climates from cold semi-arid climates, a mean annual temperature of 18 °C (64.4 °F) is used as an isotherm.
