Polar deserts are one of two polar biomes, the other being Arctic tundra. These biomes are located at the poles of Earth, covering much of the Antarctic in the southern hemisphere, and in the northern hemisphere extending from the Arctic into North America , Europe and Asia .
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). Some of Earth 's biggest non-polar deserts
Deserts are also classified, according to their geographical location and dominant weather pattern, as trade wind, mid-latitude, rain shadow, coastal, monsoon, or polar deserts. [36] Trade wind deserts occur either side of the horse latitudes at 30° to 35° North and South.
The Arctic desert ecoregion (WWF ID: PA1101) is a terrestrial ecoregion that covers the island groups of Svalbard, Franz Josef Land, Severny Island and Severnaya Zemlya in the Arctic Ocean, above 75 degrees north latitude. The region is covered with glaciers, snow, and bare rock in a harshly cold environment.
A snowy landscape of Inari located in Lapland A polar bear with cub. On Earth, the only continent where the ice cap polar climate is predominant is Antarctica. All but a few isolated coastal areas on the island of Greenland also have the ice cap climate. Summits of many high mountains also have ice cap climate due to their high elevation.
Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
Bayuda Desert – a desert covering eastern Sudan located just at the southwest of the Nubian Desert; Sinai Desert – a desert located on the Sinai Peninsula in Egypt; Atlantic Coastal Desert – a desert lying along the western coast of the Sahara Desert and occupies a narrow strip in Western Sahara and Mauritania
Regions under the polar high also experience very low levels of precipitation, which leads them to be known as "polar deserts". Air flows outwards from the poles to create the polar easterlies in the Arctic and Antarctic areas.
