In winter, this relatively warm water, even though covered by the polar ice pack, keeps the North Pole from being the coldest place in the Northern Hemisphere, and it is also part of the reason that Antarctica is so much colder than the Arctic. In summer, the presence of the nearby water keeps coastal areas from warming as much as they might ...
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 ...
Cold Arctic air intrudes into the warmer lower latitudes more rapidly today during autumn and winter, a trend projected to continue in the future except during summer, thus calling into question whether winters will bring more cold extremes. [165] A 2019 analysis of a data set collected from 35 182 weather stations worldwide, including 9116 ...
Storms feed off of the temperature difference between the cold Arctic air and warmer lower latitudes. The result is two-fold, says Furtado: “Now we will have more energetic storms that are able ...
The temperatures were, on average, warmer, producing wet, warm winters and hot summers in Norway. [citation needed] This has led to increased precipitation extremes, and changes in fish stocks. [citation needed] Increased atmospheric temperatures due to global climate change cause strong south westerly winds to pile water up along the Norwegian ...
Bitterly cold air that originated in Siberia will arrive in the U.S. in the coming days, resulting in dangerously cold wind chills for millions of Americans. Arctic blast from polar vortex to send ...
Every year, sea ice cover in the Arctic Ocean shrinks to a low point in mid-September. As the Intergovernmental Panel on Climate Change has shown, carbon dioxide levels in the atmosphere are ...
Svalbard is located in between two ocean currents – the warm Atlantic West Spitsbergen Current and the cold Arctic East Spitsbergen Current. [3] These currents have a large impact on the climate of Svalbard and in the distribution of sea ice. The warm Atlantic current on the west coast leads to an average sea temperature of 5–7 °C. [4]
