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.

“Perennially ice-covered freshwater ecosystems are hotspots of biodiversity in Antarctica’s polar deserts, providing a year-round oasis for microbial life,” the authors wrote.
Because of the lack of precipitation and low temperatures the Arctic and Antarctic are considered the world's largest deserts or Polar deserts. [1] [2] Much of the radiation from the Sun that is received is reflected off the snow making the polar regions cold. [3] When the radiation is reflected, the heat is also reflected.
In North America, these areas of frigid, polar air usually impact Canada and portions of the northern tier of the United States. These pushes of air are often referred to as "Arctic outbreaks" due ...
