The shortest, or great circle, route for a Soviet air attack on North America was through the Arctic, across the area around the North Pole.The DEW Line was built during the Cold War to give early warning of a Soviet nuclear strike, to allow time for United States bombers to get off the ground and land-based intercontinental ballistic missile (ICBMs) to be launched, to reduce the chances that ...
Air France was the first to operate commercial jet service over the North Pole on the routing Tokyo – Anchorage – Hamburg – Paris on 18 February 1960 using Boeing 707-328 Intercontinental equipment. During the Cold War, the Arctic region was a buffer zone between the Soviet Union and North America.
The Distant Early Warning Line, also known as the DEW Line or Early Warning Line, was a system of radar stations in the far northern Arctic region of Canada, with additional stations along the North Coast and Aleutian Islands of Alaska, in addition to the Faroe Islands, Greenland, and Iceland. It was set up to detect incoming Soviet bombers ...
Cold subsides when the vortex restabilizes and drives the arctic air back north. January’s freeze-out comes after December started cold, but finished out unusually warm across most of the country.
An arctic blast will send temperatures across the United States plummeting as bitterly cold air that originated in Siberia will arrive from Canada by week’s end, bringing with it dangerously ...
The polar vortex, which is a storm at the jet stream level of the atmosphere, has kept frigid air pent up above the Arctic Brief visit from polar vortex to bring record-challenging cold to ...
The Arctic tree line is the northernmost latitude in the Northern Hemisphere where trees can grow; farther north, it is too cold all year round to sustain trees. [23] Extremely low temperatures, especially when prolonged, can freeze the internal sap of trees, killing them.
When it is very weak, the flow of Arctic air becomes more disorganized, and masses of cold Arctic air can push equatorward, bringing with them a rapid and sharp temperature drop. [5] A deep freeze that gripped much of the United States and Canada in late January 2019 has been blamed on a "polar vortex". This is not the scientifically correct ...
