The event occurred in early 2014 and was caused by a southward shift of the North Polar Vortex. Record-low temperatures also extended well into March. On January 2, an Arctic cold front initially associated with a nor'easter tracked across Canada and the United States, resulting in heavy snowfall in some areas. Temperatures fell to ...
The breakup of the northern polar vortex occurs between mid March to mid May. This event signifies the transition from winter to spring, and has impacts on the hydrological cycle, growing seasons of vegetation, and overall ecosystem productivity. The timing of the transition also influences changes in sea ice, ozone, air temperature, and ...
Polar vortex. It's a phrase that becomes very popular has achieved buzzword status and is often used frequently during the winter as the Northern Hemisphere endures its coldest months of the year ...
The 1985 North America cold wave [1] was a meteorological event which occurred in January 1985 as a result of the shifting of the polar vortex farther south than is normally seen. [1] Blocked from its normal movement, polar air from the north pushed into nearly every section of the central and eastern half of the United States and Canada ...
The polar vortex is not synonymous with a cold snap. In fact, the stratosphere is 10 to 30 miles above the earth’s surface and above the polar jet stream and other systems that create most ...
The polar vortex is a large area of low-pressure and cold air surrounding both of the Earth’s poles, according to the weather service. It always exists near the poles.
Starting in late December as a result of the southward shift of the polar vortex, extremely cold conditions froze the eastern United States in the last few days of 2017 as well as into the new year. Following a brief respite in mid-January, cold temperatures swung back into the eastern U.S. shortly afterwards.
The polar vortex is extensive coverage of low pressure and cold air surrounding Earth’s poles. When the vortex is strong and stable, the polar jet stream shifts northward, keeping the cold air ...
