According to a new study, published Thursday in the journal Science, rising temperatures in the Arctic and subsequent disruptions to the polar vortex have increased the risk of extreme winter weather and prolonged cold-spells in North America.
Typically, the stratospheric polar vortex holds a tight circular pattern, keeping cold air trapped above the Arctic. The vortex’s structure is stabilized by the temperature difference between polar air and the more temperate air to the south. The Arctic is warming faster than the rest of the planet, and according to satellite imaging, the shape of the stratospheric polar vortex has become less stable over the last 40 years.
