As the Arctic rapidly warms, the temperature difference between the polar region and lower latitudes decreases, which weakens ...
Several hypotheses for how Arctic warming may be influencing mid-latitude weather patterns have been proposed recently. For example, Arctic warming could lead to a weakened jet stream resulting in ...

Why Polar Vortexes Are Becoming More CommonUnderstanding 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 ...
One of the most devastating (and hardest to mitigate) effects of climate change for the Northern Hemisphere is the slowing of ...
In Earth's upper atmosphere, a fast-moving band of air called the jet stream blows with winds of more than 275 miles (442 km) per hour, but they are not the strongest in our solar system. The ...
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.
A strong polar vortex in the stratosphere has brought subzero temperatures to the Midwest, Mid-Atlantic and deep into the South.
