Satellites orbiting the Earth have captured the effects ... The satellite image is a stark visual representation of the results of the "polar vortex" weather system on the U.S., where it sparked ...

The polar vortex hasn’t just been discovered; it has been around for as long as Earth has had an atmosphere. It’s a cold, swirling whirlpool of low pressure surrounding both o ...

Miles above the Earth, two bands of fast-moving air – the polar jet stream and the stratospheric polar vortex – sometimes tango together to influence weather in the northern hemisphere.

The polar vortex is within the stratosphere. Because of the lack of sunlight, both the Earth's poles have substantially cooler temperatures than the equator. This means the air at the poles gets ...

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 ...

It's a term you hear every couple of winters, when we get stuck in the coldest of cold patterns – polar vortex. But what exactly is it and how does it impact our weather? The polar vortex is ...

Most of the US will enjoy milder temperatures on Thursday, but the warmup will be brief as a polar vortex will send temperatures tumbling below freezing for most of the nation starting this ...

Miles above the Earth, two bands of fast-moving air – the polar jet stream and the stratospheric polar vortex – sometimes tango together to influence weather in the northern hemisphere. As the Arctic ...
