Three factors are combining to increase the likelihood of a weaker polar vortex this winter, the website reports. And a ...

The polar vortex is technically in the stratosphere, the middle layer of Earth's atmosphere. That area of low pressure is about 20 miles (32 kilometers) above the Earth's surface, Furtado said.

The polar vortex appears to be on the move. That’s because stratospheric warming is occurring at high altitudes above the North Pole, resulting in a spike in temperatures.

Polar vortex brings dangerous cold 02:16. With the Northern Hemisphere well into the winter months, it may seem like temperatures are cold enough already.

These polar vortex stretches are happening more frequently as the world — and especially the Arctic — warms, a 2021 paper published in the journal Science, also co-authored by Cohen, demonstrated.

The polar vortex – everyone's favorite wintertime whipping boy – is actually a gigantic, circular area of cold air high up in the atmosphere that typically spins over the North Pole ...

While most polar vortex forecasts are often unpredictable, Fox Weather said this round of cold is different. “This is a very highly confident forecast.

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 ...

The polar vortex is a broad region of freezing air that lives above the North Pole. It can make for frigid weather when the jet stream, which usually holds it in place, bends and lets that cold ...

“The polar vortex is often considered a part of that mechanism,” Butler wrote in her email. The 2018 paper that found a link between weaker vortices and severe winter weather, ...

Disruptions to the polar vortex can cause severe weather in the U.S., such as in 2021 when Louisville, Kentucky saw "an abrupt end to the mostly tranquil weather the region had experienced for ...

A polar vortex could bring cold winds to much of the U.S. as the new year approaches—but what exactly is a polar vortex, and how could it affect the weather in 2025? Why It Matters.
