- Polar vortex - Wikipedia
A polar vortex, more formally a circumpolar 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]

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 polar vortex is an area of low pressure—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
- Polar vortex | Meteorology, Climate Change, Arctic Weather - Britannica
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

What is a polar vortex? A polar vortex is an area of low pressure and cold air that surrounds the North and South poles, according to the National Weather Service

Instead, the polar vortex occurs primarily in the stratosphere, a layer of the atmosphere about 6 to 30 miles above the ground – above most of the weather with which you're familiar occurs

The polar vortex is a large mass of cold air that spins around the North Pole every winter It is not a single storm but a broad circulation pattern in the atmosphere that helps contain Arctic air in the polar regions
- What is the polar vortex? - National Snow and Ice Data Center
The polar vortex is the region of the atmosphere that contains the hemisphere’s cold air, rotating from west to east In the Northern Hemisphere, the axis of the rotation is generally located in the Arctic
- Polar Vortex - an overview | ScienceDirect Topics
The polar vortex, also known as the polar low or polar cyclone, is a large area of persistent low pressure containing a mass of extremely cold air, generally located above Earth’s polar regions (Rafferty, 2017)

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 ) The stronger the winds, the more the air inside is isolated from warmer latitudes, and the colder it gets
