A strong, stable vortex is like a skater spinning with their arms tucked closely in, holding in an area of cold air over the Arctic. But when there’s a wobble in the rotation, winds in the vortex can ...

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

How the Polar Vortex Can Bring Arctic Blasts to the U.S. Vast weather patterns can carry blasts of frigid air far from the ...

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

A mass of air called the polar vortex has escaped the Arctic and plunged southward. Some scientists see the fingerprints of ...

Here's how the polar vortex, and climate change, influence extremely cold winter weather in the US. Intense snowy wintry weather in the US has been fuelled by activity of the polar vortex ...

But some emerging science suggests that, generally, the polar vortex could be changing as a result of global warming, possibly causing more cold extremes in North America. Warming temperatures at ...

The polar vortex can be disrupted by factors such as natural turbulence, high-latitude ocean warming, sea ice loss, sudden atmospheric warming, planetary waves and climate change, says the National ...

Florida farmers will fill 3 million fewer boxes of oranges this growing season than they projected to pre-Hurricane Milton, ...

These severe cold events occur when the polar jet stream – the familiar ... But does this cold snap contradict human-caused global warming? As an atmospheric and climate scientist, I can tell ...
