The climate of the Arctic is characterized by long, cold winters and short, cool summers. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter.
Average January temperatures range from about −40 to 0 °C (−40 to 32 °F), and winter temperatures can drop below −50 °C (−58 °F) over large parts of the Arctic. Average July temperatures range from about −10 to 10 °C (14 to 50 °F), with some land areas occasionally exceeding 30 °C (86 °F) in summer.
"Cold arctic air gripped western Europe in the first three weeks of December. Two major snowstorms, icy conditions, and frigid temperatures wreaked havoc across much of the region...The harsh winter weather was attributed to a negative Arctic Oscillation, which is a climate pattern that influences weather in the Northern Hemisphere.
As for precipitation, he said, "so far this winter, the patterns seen over the U.S., including drier than average conditions across the southern tier, and wetter than average conditions in the ...
Arctic blast from polar vortex to send temperatures plunging across the U.S. ... part of the polar vortex — a large area of cold air that spins over the North Pole in the winter — will drop ...
That means arctic air is blasting over the US, while pressure changes and the motion of the polar vortex whip up high winds and create a perfect recipe for wintry weather.
Climate is defined by the World Meteorological Organization as the average weather over a 30-year period. [1] The North Atlantic Current moderates Svalbard's temperatures, particularly during winter, giving it up to 20 °C (36 °F) higher winter temperature than similar latitudes in continental Russia and Canada. This keeps the surrounding ...
The Arctic region is especially vulnerable to the effects of any climate change, as has become apparent with the reduction of sea ice in recent years. Climate models predict much greater climate change in the Arctic than the global average, [46] resulting in significant international attention to the region. In particular, there are concerns ...
