A map of the Arctic. The red line is the 10 °C isotherm in July, commonly used to define the Arctic region; also shown is the Arctic Circle. The white area shows the average minimum extent of sea ice in summer as of 1975. [1] The climate of the Arctic is characterized by long, cold winters
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 ...
Relationship of Earth's axial tilt (ε) to the tropical and polar circles. The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the Sun can remain continuously above or below the horizon for twenty-four hours; as a result, at least once each year at any location within the Arctic Circle the centre of the Sun is visible at local midnight, and at least ...
It's the first significant Arctic outbreak of the season and it will arrive in the northern Rockies and northern Plains on Thanksgiving and Friday, the National Weather Service said. The cold will ...
The Thanksgiving day storm will largely be out of the East by sunrise but lake-effect snow will start up for areas downwind of the Great Lakes as Arctic air rushes over the record-warm lakes.
The weather service says lake-effect snow is produced when a cold airmass moves south from Canada and beyond over the comparatively warm Great Lakes, pulling some of the lake water quickly into ...
If the warming exceeds - or thereabouts, there is a significant risk of the entire ice sheet being lost over an estimated 10,000 years, adding up to global sea levels. Warming in the Arctic may affect the stability of the jet stream, and thus the extreme weather events in midlatitude regions, but there is only "low confidence" in that hypothesis.
A powerful Arctic cold front was sweeping across the Great Lakes to the Northeast, ... at least snow-free. Truly dry weather will be a longer wait." ... Some school districts closed for the day or ...
