The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole .
At the time, this was the coldest reliably measured temperature for the Northern Hemisphere. The weather station is in a valley between Oymyakon and Tomtor . The station is at 750 m (2,460 ft) and the surrounding mountains at 1,100 m (3,600 ft), causing cold air to pool in the valley: recent studies show that winter temperatures in the area ...
These data became available after the Cold War, and have provided evidence of thinning of the Arctic sea ice. The Soviet navy also operated in the Arctic, including a sailing of the nuclear-powered ice breaker Arktika to the North Pole in 1977, the first time a surface ship reached the pole.
Driven by the jet stream, part of the polar vortex — a large area of cold air that spins over the North Pole in the winter — will drop about 3,000 miles south into the U.S., delivering the ...
The Arctic has various definitions, including the region north of the Arctic Circle (currently Epoch 2010 at 66°33'44" N), or just the region north of 60° north latitude, or the region from the North Pole south to the timberline. [1] The Antarctic is usually defined simply as south of 60° south latitude, or the continent of Antarctica.
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.
At the South Pole, the highest temperature ever recorded was −12.3 °C (9.9 °F) on 25 December 2011. [16] Along the Antarctic Peninsula, temperatures as high as 18.3 °C (64.9 °F) have been recorded, [clarification needed] though the summer temperature is below 0 °C (32 °F) most of the time. Severe low temperatures vary with latitude ...
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.
