Mar 5, 2021 · Polar vortex expert Amy Butler and Arctic expert James Overland offer perspectives on the February cold snap in the southern U.S., the polar vortex, and how the Arctic might influence mid-latitude weather.
Feb 1, 2023 · Some researchers link disruptions to the polar vortex to climate change, while others attribute them to natural variability.
May 21, 2024 · The polar jet stream and polar vortex are two rings of fast-moving air around the Arctic, which play a large role in world weather patterns. Many climate scientists believe that global warming is changing these rings, in ways that allow freezing air from the Arctic to intrude on the warmer mid-latitude regions.
Dec 21, 2022 · An influx of Arctic air is blasting across the U.S., sending temperatures plunging, dropping snow, disrupting Christmas travel plans, and setting social media atwitter about the polar vortex. But what exactly is the polar vortex? Where does the cold air come from? And is global warming making cold snaps like this one more likely?
Jan 16, 2024 · The latest forecast says a major disruption of the polar vortex is on its way, but the stratosphere has been acting up for a while. Our bloggers explain what it might mean for U.S. weather.
Dec 22, 2022 · The polar vortex is descending on the Northeastern United States, bringing bitterly cold Arctic air and causing temperatures to plunge rapidly.
Dec 5, 2023 · Those changes in the polar vortex winds could then alter regional climate change at the surface, by changing weather patterns. So the polar vortex's *response* to climate change in theory can modulate how climate change is felt at the surface.
Dec 20, 2022 · The polar vortex is a well-documented, long-existing pattern, but some scientists say climate change could be making it unstable, with potentially serious consequences. How does the polar...
Nov 5, 2021 · While the polar vortex is well documented, its behavior has become more extreme as a result of climate change, according to Ullrich. He explains: warming of the Earth has led to the loss of Arctic sea ice, transforming a highly reflective icy surface to a dark absorptive surface.
Aug 7, 2024 · Polar motion, a small variation of the Earth’s rotational axis, is primarily caused by the Chandler wobble. The Chandler wobble has a period of roughly 14 months and is mainly caused by the ...
