Another benefit from the Cold War was the acquisition of observations from United States and Soviet naval voyages into the Arctic. In 1958 an American nuclear submarine, the Nautilus was the first ship to reach the North Pole. In the decades that followed submarines regularly roamed under the Arctic sea ice, collecting sonar observations of the ...
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.
The Arctic is a region around the North Pole (90° latitude). Its climate is characterized by cold winters and cool summers. Precipitation mostly comes in the form of snow. Areas inside the Arctic Circle (66°34′ latitude) experience some days in summer when the Sun never sets, and some days during the winter when it never rises. The duration ...
Summer ice cover in the Arctic is about 50% of winter cover. [1] Some of the ice survives from one year to the next. Currently, 28% of Arctic basin sea ice is multi-year ice , [ 2 ] thicker than seasonal ice: up to 3–4 m (9.8–13.1 ft) thick over large areas, with ridges up to 20 m (65.6 ft) thick.
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 ...
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 ...
