- The polar vortex is a large area of cold, rotating air that encircles both of Earth's polar regions12345. It is a low-pressure system that exists near the poles and weakens in summer but strengthens in winter2. The vortex influences the jet stream and can bring cold winter weather to regions like the U.S. and Europe5.Learn more:✕This summary was generated using AI based on multiple online sources.

Polar vortices also exist on other rotating, low- obliquity planetary bodies. [1]en.wikipedia.org/wiki/Polar_vortexThe 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.www.weather.gov/safety/cold-polar-vortexThe 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.scijinks.gov/polar-vortex/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 mid-latitudes, such as the United States and Europe.www.wunderground.com/article/science/weather-e…The polar vortex is an enormous, 3-dimensional ring of winds that surrounds the North and South poles during each hemisphere’s winter.
