Some parts of the Arctic are covered by ice (sea ice, glacial ice, or snow) year-round, especially at the most poleward parts; and nearly all parts of the Arctic experience long periods with some form of ice or snow on the surface. Average January temperatures range from about −40 to 0 °C (−40 to 32 °F), and winter temperatures can drop ...
At the North Pole on the June solstice, around 21 June, the sun circles at 23.5° above the horizon. This marks noon in the Pole's year-long day; from then until the September equinox, the sun will slowly approach nearer and nearer the horizon, offering less and less solar radiation to the Pole. This period of setting sun also roughly ...
While the South Pole lies on a continental land mass, the North Pole is located in the middle of the Arctic Ocean amid waters that are almost permanently covered with constantly shifting sea ice. The sea depth at the North Pole has been measured at 4,261 m (13,980 ft) by the Russian Mir submersible in 2007 [ 1 ] and at 4,087 m (13,409 ft) by ...
"The Arctic air coming through Jan. 15th can be the coldest of the winter so far," Anderson said. "This batch of Arctic air will have a vast zone for fresh snow cover to work with and a direct ...
Arctic blast brings snow, frigid temperatures across U.S., with 175M under cold weather alerts ... Houston’s George Bush Intercontinental Airport was scheduled to close at 12 a.m. local time ...
[15] [16] Since 2013, Arctic annual mean surface air temperature (SAT) has been at least 1 °C (1.8 °F) warmer than the 1981-2010 mean. In 2016, there were extreme anomalies from January to February with the temperature in the Arctic being estimated to be between 4–5.8 °C (7.2–10.4 °F) more than it was between 1981 and 2010. [17]
The wide-reaching impact of the extreme cold could include local economies, stress power grids with increased heating demands, force some schools to close, and endangering health with "real feel ...
The word Arctic comes from the Greek word ἀρκτικός (arktikos), "near the Bear, northern" [4] and from the word ἄρκτος (arktos), meaning bear. [5] The name refers either to the constellation known as Ursa Major, the "Great Bear", which is prominent in the northern portion of the celestial sphere, or to the constellation Ursa Minor, the "Little Bear", which contains the celestial ...
