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

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. Here's what to expect.

A polar vortex “is a large area of low pressure and cold air surrounding both of the Earth’s poles,” the NWS explains. In the Northern Hemisphere, the vortex tends to expand in the winter ...

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 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.

A polar vortex disruption is underway. What it means is up in the air. Scientists still can’t yet say how a massive warming in the stratosphere above the North Pole will affect our weather ...

In a year without much winter weather, there’s a chance of a bitter blow before spring takes hold. Experts say a disruption of the polar vortex could unleash cold, stormy conditions to the ...

We've mentioned the polar vortex several times in recent days. We've said, for instance, that it's "a low pressure system that's usually whirling around the North Pole but has weakened and come ...
