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 ...

The vortex can sometimes shift away from the pole, stretch or even split in a way that sends bitter cold plunging into midlatitudes. Those disruptions to the circulation are happening more often as ...

Understanding the Polar Vortex The polar vortex is like a massive whirlpool of frigid air moving around our planet's poles. Think of it as a barrier that, when strong, keeps icy polar air trapped up ...

Winter in the CSRA is usually mild overall, but every now and then, we get a taste of true Arctic air. If you’ve ever ...

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 ...

Some researchers do believe there is a connection between climate change and the impact to the Arctic and polar vortex activity, but for others this is still an active area of investigation.

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 ...

Abnormal weather events and severe winter storms could be caused by a disrupted polar vortex. Find out here how the polar ...

Some researchers do believe there is a connection between climate change and the impact to the Arctic and polar vortex activity, but for others this is still an active area of investigation.

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

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 ...

Those disruptions to the circulation are happening more often as global warming has weakened the polar vortex. What’s less clear is whether those events are also leading to bouts of cold on the ...
