A polar climate consists of cool summers and very cold winters (or, in the case of ice cap climates, no real summer at all), which results in treeless tundras, glaciers, or a permanent or semi-permanent layer of ice. It is identified with the letter E in the Köppen climate classification.
Cold subsides when the vortex restabilizes and drives the arctic air back north. January’s freeze-out comes after December started cold, but finished out unusually warm across most of the country.
Relationship of Earth's axial tilt (ε) to the tropical and polar circles. The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the Sun can remain continuously above or below the horizon for twenty-four hours; as a result, at least once each year at any location within the Arctic Circle the centre of the Sun is visible at local midnight, and at least ...
A map of the Arctic. The red line is the 10 °C isotherm in July, commonly used to define the Arctic region; also shown is the Arctic Circle. The white area shows the average minimum extent of sea ice in summer as of 1975. [1] The climate of the Arctic is characterized by long, cold winters
A blast of Arctic air will bring punishing cold winds and bands of heavy lake-effect snow that will bury some towns in fresh feet of snow into Friday, AccuWeather meteorologists warn. However, the ...
A quick but intense blast of Arctic air will barrel into the Northeast later this week to deliver quite a cold shock to the Northeast and neighboring Canada, AccuWeather meteorologists warn. The ...
The Arctic's indigenous people have a long relationship with its icy conditions, and face the loss of their cultural heritage. Further, there are numerous implications which go beyond the Arctic region. Sea ice loss not only enhances warming in the Arctic but also adds to global temperature increase through the ice-albedo feedback.
Midnight sun at the North Cape on the island of Magerøya in Norway. Midnight sun, also known as polar day, is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the Sun remains visible at the local midnight.
