  • Understanding the Arctic polar vortex - NOAA Climate. gov
    When the vortex weakens, shifts, or splits (right globe), the polar jet stream often becomes extremely wavy, allowing warm air to flood into the Arctic and polar air to sink down into the mid-latitudes
  • Polar vortex - Wikipedia
    The stratospheric polar vortex is an area of high-speed, cyclonically rotating winds around 15 km to 50 km high, poleward of 50°, and is strongest in winter It forms during autumn when Arctic or Antarctic temperatures cool rapidly as the polar night begins
  • Polar vortex | Meteorology, Climate Change, Arctic Weather - Britannica
    Disruptions in the polar vortex can push part of the main region of frigid Arctic air southward thousands of kilometres, which produce wide-ranging “cold-air outbreaks” or “cold waves” that can decrease air temperatures to dangerous levels over populated areas of Eurasia or North America
  • Nasa Ozone Watch: Polar vortex facts
    Relatively lower values of total ozone are co-located with the polar vortex The distribution of temperatures of the lower stratosphere are similar to the distribution of total column ozone Warmest temperatures are found near and just outside the vortex
  • Polar Vortex - an overview | ScienceDirect Topics
    The linkage of the polar vortex to the ozone depletion has generated considerable interest and research into the formation and breakup of the polar vortex Below we review the development, evolution, and breakup of the polar vortex
  • What Is the Polar Vortex? | NESDIS | National Environmental Satellite . . .
    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
  • The Polar Jet Stream and Polar Vortex - MIT Climate Portal
    But some climate scientists believe that it, too, is changing in ways that affect weather further south Like the polar jet stream, a strong polar vortex helps contain the cold air at its core Sometimes, natural turbulence from below moves upward to disturb the vortex, and it can break down
  • Polar vortex | Earth and Atmospheric Sciences - EBSCO
    Other factors that are thought to affect the polar vortex include the polar jet stream, an air current that flows north over North America and Europe, and the melting of the polar ice caps
  • Learn About 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
  • What is the Cause of the Polar Vortex? Understanding the Factors Behind . . .
    The polar vortex significantly influences weather systems, especially during winter Its changes can lead to extreme weather events, altering temperature and precipitation patterns in various regions
