Polar vortex - Wikipedia
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. [1]

Dec 20, 2024 · The polar vortex is a whirling cone of low pressure over the poles that's strongest in the winter months due to the increased temperature contrast between the polar regions and the...
What is the Polar Vortex? - National Weather Service
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.
How the Polar Vortex Can Bring Arctic Blasts to the U.S.

¿Ques el Vórtice Polar? - National Weather Service
El vórtice polar es un gran área de baja presión y aire frío que rodea los polos de la Tierra. Siempre existe cerca de las zonas polares pero se debilita en el verano y se intensifica en el invierno.
The Polar Jet Stream and Polar Vortex | MIT Climate Portal
May 21, 2024 · The polar jet stream and polar vortex are two rings of fast-moving air around the Arctic, which play a large role in world weather patterns. Many climate scientists believe that global warming is changing these rings, in ways that allow freezing air from the Arctic to intrude on the warmer mid-latitude regions.
How the polar vortex fuels intense winter weather in the US - BBC
2 days ago · The polar vortex, or Arctic polar vortex, is a ring of strong westerly winds that form between 10 and 30 miles (16-48km) above the North Pole every winter, enclosing a large pool of extremely cold ...
The polar vortex: coming out of hibernation | NOAA Climate.gov
Dec 4, 2024 · We define the strength of the polar vortex by the fierceness of the west-to-east winds at a latitude of 60 degrees North and 10-hPa (~19 miles/30 kilometers). After it wakes up from its summer hibernation, the polar vortex can be a solitary creature, content to roam around by itself in the stratosphere. So why do we, at the surface, care about it?
