The polar vortex returns to the lower 48 this week, and frostbite-inducing temperatures for millions will last through next week.. Arctic air will descend and spread across the U.S. early this ...
A stretched polar vortex like this one happens lower in the atmosphere and is different than when the polar vortex has sudden warming, weakens and all the cold air escapes south and out of the ...

According to the Associated Press, this will be the 10th time this winter that the polar vortex — a large area of cold air that spins over the North Pole — will drop into the U.S., delivering ...
When the polar vortex is strong, the mid-latitude Westerlies (winds at the surface level between 30° and 60° latitude from the west) increase in strength and are persistent. When the polar vortex is weak, high-pressure zones of the mid-latitudes may push poleward, moving the polar vortex, jet stream, and polar front equatorward. The jet ...
The potentially life-threatening cold is due to a disrupted polar vortex. The FOX Forecast Center said a lobe of the polar vortex will dip to the south and move into the U.S. this weekend and into ...
Climate change in Antarctica, 2023–2024 El Niño event The 2024 Antarctica heat wave refers to a prolonged and significant mid- winter increase in Antarctic temperatures compared to prior winters, causing several regions of Antarctica to reach temperatures 10 °C (18.0 °F) above normal in July 2024, up to a 28 °C (50.4 °F) increase above ...
The polar vortex, which is a storm at the jet stream level of the atmosphere, has kept frigid air pent up above the Arctic. ... February 1, 2023 at 12:37 PM. 1 / 6.
