The polar dance that caused snow to fall across the South in January has been studied for decades, but scientists still hope ...

How the Polar Vortex Can Bring Arctic Blasts to the U.S. Vast weather patterns can carry blasts of frigid air far from the polar regions—here’s how it works ...

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 ...

One of the most devastating (and hardest to mitigate) effects of climate change for the Northern Hemisphere is the slowing of ...

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

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

The vortex is essentially an area of low pressure in the upper layers of the atmosphere over the polar region up north. This ...

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

While jet streams are air patterns, the Gulf Stream is an ocean pattern that also has an impact on weather.

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 ...

The University of Wisconsin-Madison faced a frigid start to the semester, with the polar vortex expected to bring more icy ...

“Typically going from west to east, and formed at the boundary between significantly different air temperatures, like between cold polar air and warmer tropical air.” “The jet stream is ...
