Research has found that rising temperatures in the Arctic are weakening weather systems that normally trap the cold around ...

A polar vortex dipping down from Siberia is bringing a cold front with frigid temperatures to millions Americans. See maps of ...

As the Arctic rapidly warms, the temperature difference between the polar region and lower latitudes decreases, which weakens ...

Ranked dead last, or perhaps not mentioned at all, would probably be the only state that sits partly within the Arctic Circle ...

A strong polar vortex in the stratosphere has brought subzero temperatures to the Midwest, Mid-Atlantic and deep into the South.

When Virgin Atlantic Flight 10 took off from New York’s JFK International Airport this week, it was running 1 hour 13 minutes ...

The polar vortex is expected to remain on the Canadian side of the North Pole, which will keep an abundant supply of Arctic ...

Extreme cold and snow smacked the Gulf Coast states this week, but the polar vortex may not be to blame.

The polar vortex can expand and push south with the jet stream – a narrow current of air that flows high up in the atmosphere from west to east. Notably, a polar vortex struck the US in 2019 ...

When there are disturbances in which the Jet Stream weakens, it can become wobbly. This allows the cold air to plunge southwards. A disrupted polar vortex does not happen every year. Very much so what ...

Simple physics suggests changes to polar vortex and jet-stream patterns are logical responses to the dramatic changes humans have caused to Earth’s natural systems, said Andrew Dessler ...

So, that's why jet streams are important.” 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 ...
