Jet streams are fast flowing, narrow air current
Thermal wind
The thermal wind is a vertical shearing in the geostrophic wind Causality by a horizontal temperature gradient.
Jet Streams:
Among the more fascinating features of upper-air circulations are discontinuous bands of relatively strong winds (usually in excess of 30 metres per second) called jet streams.

Jet Stream. The core of fast air flow associated with the westerlies, occurring close to the top of the troposphere. Because of its high speed, it may also affect airliner schedules.
JET STREAM
The jet stream is a high-speed wind that is usually found at high altitudes, between 25,000 and 45,000 feet (just below the tropopause).
Jet Stream
The Northern Hemisphere Jet Stream can be seen crossing Cape Breton Island in the Maritime Provinces of Eastern Canada.
The jet stream powers around the ringed planet at about 100 metres per second (220 mile per hour) at a latitude of about 77 degrees north, and spans a diameter wider than the equivalent of two Earths.
The jet stream is a belt or band of rapidly moving air from 50,000 feet in altitude, or above, crossing the mid-latitudes of the U.S. Actually, there are two jet streams. One in the far northern U.S.
The jet stream contributes to turbulence both directly through its high velocity movement against lower atmospheric layers, and indirectly through the quantity of cold or moist air it brings from northern latitudes and ocean surfaces, ...

jet stream (NASA Thesaurus / NASA SP-7, 1965) A strong band of wind or winds in the upper troposphere or in the stratosphere, moving in a general direction from west to east and often reaching velocities of hundreds of miles an hour.
In the meteorological sense jet stream is two words, see following definition, but in the sense defined above, one word.
Alternate jet streams of east-west and west-east circulation can be traced in the motions of the cloud tops, the speeds of these jet streams reach speeds of hundreds of metres per second, they are the cause of the banded appearance of the clouds.
The weather was tame compared with Jupiter: massive jet streams with minimal variance (a 33-year great white spot/band cycle is known). Titan's atmosphere was smoggy.
The powerful, narrow jet streams deflect the clouds into belts moving parallel to the planet equators. The winds in a belt move in the opposite direction of the belt next to it. Large vortices can from from the interplay of the belts.
Above the clouds, a high-speed "jet stream" blows from west to east at about 300"400 km/h, fastest at the equator and slowest at the poles. This high-altitude flow is responsible for the rapidly moving cloud patterns seen in ultraviolet light.
Unlike the north pole, HST imaging of the south polar region indicates the presence of a jet stream, but no strong polar vortex nor any hexagonal standing wave.
Features revealed by helioseismology include that the outer convective zone and the inner radiative zone rotate at different speeds to generate the main magnetic field of the Sun, and that the convective zone has "jet streams" of plasma thousands of ...
Massive jet streams which change rarely.
Saturn's magnetic poles lie exactly on its true north and south poles.
Titan, a moon, has a smoggy atmosphere, mostly composed of nitrogen, and at the surface has a density about 1.
Its placid-looking, butterscotch-colored face masks a windswept atmosphere where jet streams blow at 1,100 miles per hour and swirling storms roil just beneath the cloud tops.
Saturn Why does Saturn's atmosphere show fewer features than Jupiter? Why does Saturn have the fastest jet streams in the solar system?
Saturn is the second-largest planet in the Solar System and is made up mostly of hydrogen and helium. Its placid-looking, butterscotch-colored face masks a windswept atmosphere where jet streams blow at 1, ...
Uranus has a magnetic field from which the rotation rate of the unseen `body' of the planet can be deduced as just over 17 hours. This is smaller than the rate determined from the few cloud structures seen, indicating that there are strong jet ...
In World War II, gas-filled barrage balloons with cables hanging from them were used to interdict low-flying aircraft in the Battle of Britain. Also, the Japanese attempted to send bombs to the US via balloons carried in the jet stream; ...
An animation of one rotation is shown in the adjacent image; here is a more extensive MPEG movie (492 kB) made from a series of Hubble observations (Ref). These images show a powerful equatorial jet stream, immense storms, ...
Stratosphere
the cold region of a planetary atmosphere above the convecting regions (the troposphere), usually without vertical motions but sometimes exhibiting strong horizontal jet streams.
Obviously, these circulation patterns set the conditions that characterize all the Earth's major climactic zones. At the interstices between the cells, strong westerly wind bands known as jet streams develop.
