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

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 ...

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

The polar regions cool dramatically ... That’s not an issue at night — so the jet stream accelerates. This is especially true over the ocean. Even though the speed of sound at sea level ...

WASHINGTON, Jan 21 (Reuters) - In Earth's upper atmosphere, a fast-moving band of air called the jet stream blows with winds ... side always faces away - the night side. Its atmosphere is about ...

Metro Vancouverites may face unseasonably cold weather as February continues thanks to the stratospheric polar vortex.

Well, the polar jet stream keeps the cold polar air trapped in the upper latitudes and upper atmosphere. Depending on the strength of the polar jet stream determines how the Polar Vortex moves.
