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 "increase" with elevation by as much as 10 °C (18 °F). [6] The average temperature in Oymyakon has risen about 2.7 degrees Celsius since preindustrial times.
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 ...
In 1908 he managed to lower the temperature to less than −269 °C (−452.2 F, 4 K), which is four degrees above absolute zero. Only in this exceptionally cold state will helium liquefy; the boiling point of helium being at −268.94 °C (−452.092 F). Kamerlingh Onnes received a Nobel Prize for his achievement. [9]
The currents then bend to the right, heading north. At about 30 degrees north latitude, a different set of winds, the westerlies, push the currents back to the east, producing a closed clockwise loop. [2] Its surface is 60.7% water, compared with 80.9% water in the case of the Southern Hemisphere, and it contains 67.3% of Earth's land. [3]
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 clock is ticking for families hoping to send letters to Santa Claus at the North Pole this holiday season. Letters need to be postmarked by Monday, a spokesperson for the U. S. Postal Service ...
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.
