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

A strong, stable vortex is like a skater spinning with their arms tucked closely in, holding in an area of cold air over the ...

How do warming arctic temperatures and a wavier jet stream combine to create snowfall across South Carolina? It's complicated ...

The jet stream is indicated by the light blue line ... the stratospheric polar vortex and mid-latitude winter weather would improve our ability to anticipate these events and their severity.

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 ...

reduces the temperature gradient between the Arctic and mid-latitudes, potentially leading to a more meandering jet stream. This increased waviness can result in prolonged weather patterns ...

After our coldest January in 11 years, February is set to start warm and, at times, wet. But the weather may turn cold and ...

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

Warmer temperatures are a welcome departure from the snow storm that hit several parts of South Carolina last week.
