A detailed analysis of polar vortex collapse mechanisms and how they relate to occasional North American cold outbreaks. Based on recent meteorological studies and stratospheric data, the video ...

The winter weather outlook from both Farmers' Almanac and the Old Farmer's Almanac predict tough conditions ahead for 2025.

As the polar vortex intensifies, it’s set to have a significant impact on Earth’s climate. Learn how this atmospheric ...

The polar vortex is an area of swirling cold air in the Earth's polar regions. During winter, the polar vortex at the North Pole expands, sending cold air southward, according to the National ...

The polar vortex is notoriously unpredictable, and so far there doesn’t seem to be clear pattern in disruptions. In the 1990s, there were almost no disruptions to it.

The polar vortex is a counterclockwise spinning area near the top of the atmosphere and usually centered near the North Pole region. This fast spinning vortex is about 50,000 feet in the atmosphere.

The polar vortex does not, by itself, cause the severe cold spells we might see in a weather forecast. But the polar vortex interacts closely with the jet stream, which is a shallower flow of ...

Those rumors came from a weather blog in north Texas that posted about the "polar vortex" a few days after Christmas. At the moment, there is no cold air outbreak in the forecast, even extended.

The polar vortex can't be felt in the United States or anywhere on Earth. Brutally cold temperatures are heading to the Midwest and Northeast this week -- but don't mistake this for a polar vortex ...

The science behind the polar vortex is incredibly complicated, and we've only recently begun to understand how changes at our planet's poles impact weather at more moderate latitudes.

The term was revised in 1950, when it was called a “circumpolar vortex,” then back to “polar vortex” by 1959. The American Meteorological Society glossary revised the definition in 2000 ...

When the polar vortex weakens or even splits, it allows frigid air to escape and push southward toward the USA. The stronger the polar vortex, the milder the USA's winter is.
