A circumpolar vortex, or simply polar vortex, is a large region of cold, rotating air; polar vortices encircle both of Earth's polar regions. Polar vortices also exist on other rotating, low-obliquity planetary bodies.
Dec 20, 2022 · The polar vortex is a well-documented, long-existing pattern, but some scientists say climate change could be making it unstable, with potentially serious consequences. How does the polar...
The polar vortex is a large area of low pressure and cold air surrounding both of the Earth’s poles. It ALWAYS exists near the poles, but weakens in summer and strengthens in winter. The term "vortex" refers to the counter-clockwise flow of air that helps keep the colder air near the Poles.
polar vortex, large area of persistent low pressure generally located above each of Earth’s polar regions and containing a mass of extremely cold air.
Mar 5, 2021 · 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.)
Oct 19, 2023 · Polar vortex is the name given to the strong currents of wind formed by low pressure that occurs in the Arctic and Antarctic regions. The name originates from the fact that these winds circulate and form a vortex near the North and South Poles of the planet.
Jan 5, 2024 · A polar vortex holds back frigid air like a dam. The polar vortex is a broad area of low pressure high in the atmosphere above the Arctic that strengthens in the winter and weakens in the...
Jan 11, 2021 · In the lowest layer of the atmosphere, the troposphere—where weather occurs—there spins a polar vortex that circles the globe year round, a jet stream that’s also sometimes referred to as the...
Dec 22, 2022 · The polar vortex is descending on the Northeastern United States, bringing bitterly cold Arctic air and causing temperatures to plunge rapidly.
Jun 13, 2024 · What Is the Polar Vortex? The Short Answer: The 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.
