At least two flights briefly traveled faster than the speed of sound as the jet stream sped up, but there would not have been ...

The jet stream is like a river of west-to-east winds in the upper atmosphere. Airplanes use it like a highway.

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

The pronounced variability, common in Europe’s winter months, was driven by an unusually northerly jet stream that shifted weather patterns, resulting in stark regional contrasts. Northern ...

At the moment, the jet stream is “stuck in a position through central Europe”, forming a “blocked weather pattern”. This means the UK is “not likely to see any of that extreme heat in th ...

WASHINGTON - In Earth's upper atmosphere, a fast-moving band of air called the jet stream blows with winds of more than 275 ...

This stability helps keep the polar vortex — and all its bitterly cold air — locked up in the Arctic, far from places like the United States or Europe. However, when the jet stream weakens ...

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