What is an Arctic vortex?
The Arctic polar vortex is a band of strong westerly winds that forms in the stratosphere between about 10 and 30 miles above the North Pole every winter. The winds enclose a large pool of extremely cold air. (There is an even stronger polar vortex in the Southern Hemisphere stratosphere in its winter.)
When was the term polar vortex first used?
1853
The polar vortex was first described in 1853 and first observed by radiosondes during the winter in the Northern Hemisphere in 1952. However, when we use phrases like “The polar vortex is coming” or “The polar vortex is here,” we probably break the icy heart of every meteorologist.
What is a polar vortex simple definition?
The polar vortex is a large circulation of low pressure and cold air that forms every winter in the stratosphere above the North and South poles. The term vortex refers to the counter-clockwise flow of air that helps keep colder air close to the poles (left globe in graphic).
What is a arctic blast?
Arctic Blast is an efficient pain-relieving supplement that is designed to assist people with chronic pain live more fulfilling lives. This supplement completely eliminates all the inflammation and pain associated with all types of chronic pain without causing any negative effects.
Where is polar vortex now?
Currently, the polar vortex in the stratosphere is fairly large. It is centered over Siberia, extending into the polar regions and slightly into North America. You can already see the high pressure emerging in the stratosphere over east Asia.
How cold is a polar vortex?
The winds of winter In the darkness of the winter polar night, temperatures within the polar vortex can easily get lower than minus 110 F (minus 79 C). Fortunately for everyone, the stratospheric polar vortex itself won’t appear outside your front door.
Is polar vortex coming?
When the jet stream gets wavy, it can dip farther south, bringing cold air and winter storms with it. The January 2021 event pushed the polar vortex from its normal position over the North Pole all the way over to Europe and Siberia, nearly pulling it apart multiple times in the process.
How often do polar vortexes occur?
Such stratospheric warming events are common, but major disruptions like that one typically only happen about every other year, says Judah Cohen, the director of seasonal forecasting at Atmospheric and Environmental Research, a company that advises government agencies and the private sector on weather risks.
Is a polar vortex coming in 2021?
Is the polar vortex coming back?
This is exactly what happened on January 5, 2021, and will probably hit us again soon. Forecasters say we can expect the cold snap in mid to late January, and it could last in spurts into February. Again, key word: could.
Is a polar vortex rare?
Polar vortexes are not rare in the United States. But, it is important to remember that not all cold weather is the result of a polar vortex. Although a polar vortex can be pushed south, it typically remains parked in polar regions. It takes pretty unusual conditions for the vortex to weaken or migrate far south.
Is the circumpolar vortex the same as the polar vortex?
A circumpolar vortex, or simply polar vortex, is a large region of cold, rotating air that encircles both of Earth’s polar regions. Polar vortices also exist on other rotating, low- obliquity planetary bodies. The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and the tropospheric polar vortex.
Where does the polar vortex go during the winter?
A polar vortex is a low pressure area—a wide expanse of swirling cold air—that is parked in polar regions. During winter, the polar vortex at the North Pole expands, sending cold air southward. This happens fairly regularly and is often associated with outbreaks of cold temperatures in the United States.
