- This unusually strong event may have profound influences on the weather in the United States and Europe, possibly increasing the potential for paralyzing snowstorms and punishing blasts of Arctic air, with the odds of the most severe cold outbreaks highest in Northern Europe.

Mar 5, 2021 · The polar vortex doesn’t always influence winter weather in the mid-latitudes. When it does, however, the effects can be extreme. When the polar vortex is especially strong, for example, the polar jet steam tends to stay farther north and to exhibit a more zonal flow, with less meandering.
Jan 28, 2021 · Butler: In general, disruptions of the polar vortex can cause cold air outbreaks over much of Europe, Asia, and the eastern USA. Other regions, like the Canadian Arctic and subtropical Africa and Asia may see much warmer than normal temperatures (Footnote #1).
Jan 11, 2021 · January 11, 2021. • 6 min read. Every year, weather enthusiasts eagerly watch and wait for signs that the polar vortex, a mass of cold air spinning around the Arctic, might meander south,...
How does the Polar Vortex affect our weather? A strong polar vortex favours a strong jet stream. The jet stream is a fast moving ribbon of air around 5 to 7 miles (8 to 11km) above the...
Jul 23, 2021 · By analysing the stream of polar cold air mass, we show that the polar vortex affects severe cold air outbreaks by modifying the inter-hemispheric transport of cold air mass.

Jan 30, 2021 · Disturbances to the upper-atmosphere phenomena known as the polar vortex can send icy blasts from the Arctic into the middle latitudes, chilling Europe, Asia and parts of North America.
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...
