jet stream

A narrow current of strong wind circling the Earth from west to east at altitudes of 10 to 15 miles (16 to 24 kilometers) above sea level. There are usually four distinct jet streams, two each in the Northern and Southern Hemispheres.

jet stream

A narrow band of high velocity wind in the upper troposphere or in the stratosphere.

jet stream

A narrow corridor of fast-moving air at high altitude.

Hauser, whose motto is 'free flight instead of free fall' also believes the renewable energy within the jet stream could have huge potential for the world.
Channel 4 weatherman Liam Dutton tweeted a graphic of its progress and said: "You can see this ripple in the jet stream travel across the ocean to the US.
An area of low pressure is set to sweep in off the Atlantic Ocean caused by an unusually strong jet stream for the time of year.
The video said the ripple would travel across the US, and will travel onwards above the Atlantic Ocean, pushing the jet stream north of the UK.
This ripple could move along the jet stream above the Atlantic ocean, pushing it north of the UK and seeing high pressure sweep in instead of low pressure.
Liam explained that this will send a "ripple" eastwards along the jet stream, comparing it to what happens "when you flick a skipping rope".
Seasonal variations are normal, however, since the planet has been warming up, these jet streams have moved more slowly, and become more deadly.
To prove this, the researchers conducted numerical simulations which showed a jet stream forming along the moon's equator and flowing opposite Europa's spin.
The 'greenhouse' effect on the climate is easily understood, even by someone as ignorant as me, but how a few parts per million of carbon moves the jet stream from side to side, remains, for me, a mystery.
A stronger ridge creates a stronger surface high-pressure system over central-eastern Asia and transports cold Arctic air over the continent, which depresses the jet stream southward into a deeper trough over Asia.
The unstable jet stream creates a pattern that "allows warm air to penetrate farther north and cold air to plunge farther south, compared to when the jet is strong and relatively straight," the report said.
