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

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

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 ...

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

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

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

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.

But here’s where things get interesting: the polar vortex’s behavior is closely tied to the jet stream, a fast-moving river of air that flows high above the Earth. The jet stream acts like a ...

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

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

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