    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
  • 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]
  • What Is the Polar Vortex? | NESDIS | National Environmental Satellite . . .
    But what exactly is the polar vortex? And what causes it? Credit: NOAA 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
  • Polar Vortex - an overview | ScienceDirect Topics
    The polar vortex is defined as the dominant meteorological system in the winter stratosphere and mesosphere, characterized by a circumpolar west-to-east jet stream that balances extremely cold air over the winter pole with warmer midlatitude air
