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

While they were embedded in a 260-mph jet stream, they weren’t cruising through the surrounding air any faster — the air was moving with them. Their ground speed was extra fast, though.

Scientists are scrambling to understand how climate change may be interfering with the winds that carry our weather, with ...

Meteorologists often blame unusual weather events on the movements of a jet stream, not to be confused with the similarly active Gulf Stream. Learn the key differences between the two before the ...

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

WASHINGTON — In Earth's upper atmosphere, a fast-moving band of air called the jet stream blows with winds of more than 275 miles per hour, but they are not the strongest in our solar system.

These severe cold events occur when the polar jet stream – the familiar jet stream of winter that runs along the boundary between Arctic and more temperate air – dips deeply southward ...

“The jet stream is a fast flowing, narrow current of air high up in the Earth's atmosphere,” said Knox. “Typically going from west to east, and formed at the boundary between significantly ...
