  2. Polar climate - Wikipedia

    en.wikipedia.org/wiki/Polar_climate

    Every month a polar climate has an average temperature of less than 10 °C (50 °F). Regions with a polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles , and in this case, winter days are extremely short and summer days are extremely long (they could last for the entirety of ...

  3. Polar regions of Earth - Wikipedia

    en.wikipedia.org/wiki/Polar_regions_of_Earth

    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.

  4. Ice cap climate - Wikipedia

    en.wikipedia.org/wiki/Ice_cap_climate

    Ice cap climate is the world's coldest climate, and includes the coldest places on Earth. With an average temperature of −55.2 °C (−67.4 °F), Vostok, Antarctica is the coldest place in the world, and has also recorded the lowest temperature, −89.2 °C (−128.6 °F). [ 3 ]

  5. Polar meteorology - Wikipedia

    en.wikipedia.org/wiki/Polar_meteorology

    Polar meteorology is the study of the atmosphere of Earth's polar regions. Surface temperature inversion is typical of polar environments and leads to the katabatic wind phenomenon. The vertical temperature structure of polar environments tends to be more complex than in mid-latitude or tropical climates.

  6. Köppen climate classification - Wikipedia

    en.wikipedia.org/wiki/Köppen_climate_classification

    The Köppen climate classification system was modified further within the Trewartha climate classification system in 1966 (revised in 1980). The Trewartha system sought to create a more refined middle latitude climate zone, which was one of the criticisms of the Köppen system (the climate group C was too general). [10]: 200–1

  7. North American Arctic - Wikipedia

    en.wikipedia.org/wiki/North_American_Arctic

    The climate of the region is known to be intensely cold during the year due to its extreme polar location. [5] The area has tundra, Arctic vegetation, [3] glaciers, and, for most of the year, is covered in thick blankets of snow and ice. [5] It is home to various species of plants, and land, air and marine animals. [6]

  8. Polar ecology - Wikipedia

    en.wikipedia.org/wiki/Polar_ecology

    Polar regions also contain the subantarctic and subarctic zone which separate the polar regions from the temperate regions. Antarctica and the Arctic lie in the polar circles. The polar circles are imaginary lines shown on maps to be the areas that receives less sunlight due to less radiation.

  9. Arctic Cordillera - Wikipedia

    en.wikipedia.org/wiki/Arctic_Cordillera

    A polar cell is a system of winds that influence the climate of the Cordillera. It is made up of the Westerlies, which are winds that blow warm air east to west from 30 to 60 degrees latitude up to the poles, and the Polar Easterlies, which blow cold air back south where it will repeat the process. [33] It was not always as cold as it is today.
