Jet Stream - Relatively strong winds concentrated in a narrow stream in the atmosphere, normally referring to horizontal, high-altitude winds. The position and orientation of jet streams vary from day to day.
Jet Stream current of rapidly moving air
The jet stream is a current of fast moving air found in the upper levels of the atmosphere.
Jet streams are fast flowing, relatively narrow air currents found in the atmosphere at around 12 km above the surface of the Earth, just under the tropopause.
Jet Stream A narrow band of strong winds in the atmosphere that controls the movement of high and low pressure systems and associated fronts. Jet Streams meander from time to time. Wind speeds can reach 200 mph or higher in certain cases.

katabatic wind—Any wind blowing downslope. See fall wind, foehn.
Jet Stream- Strong winds concentrated within a narrow band in the upper atmosphere. It normally refers to horizontal, high-altitude winds. The jet stream often "steers" surface features such as front and low pressure systems.
Jet Stream Rivers of high-speed air in the atmosphere. Jet streams form along the boundaries of global air masses where there is a significant difference in atmospheric temperature.
Jet Stream - Relatively strong winds that are concentrated in a narrow band in the atmosphere. Jet Streams are usually thousands of kilometers long, hundreds of kilometers wide but only a few kilometers thick.
The Jet Stream Changed Course.
The jet stream normally flows west over the Gulf of Mexico and turns northward pulling up moisture and dumping rain onto the Great Plains.
Polar Jet Stream: A jet stream that is associated with the polar front in the middle and high latitudes. It is usually located at altitudes between 9,000 and 12,000 km.
Polar Jet Stream
Used interchangably with Polar Jet; a jet stream marked by a concentration of isotherms and strong vertical shear, this jet is the boundary between the polar air and the subtropical air.
jet stream- fast-moving currents of air reaching 180 mph (290 kmph ) in the troposphere - 30,000 to 35,000 feet up (9,144 to 10,668 meters) - that can strengthen and shift low-pressure systems.
Jet streams- Bands of high-speed winds about 10 kilometers above Earth's surface.
Latitude- the distance from the equator, measured in degrees.
JET STREAM: Relatively strong winds concentrated within a narrow band in the atmosphere.

Jet Stream- A narrow band of winds blowing high in the troposphere at speeds in excess of 57 miles per hour or greater.
Kelvin Temperature Scale- A temperature scale in which 0 degrees is the point at which all molecular motion ceases (absolute zero).
JET STREAM - A narrow band of winds at very high altitudes which is predominantly westerly (coming from the west) and is partially responsible for the movement of pressure systems.

Jet Stream - A strong high level wind found in the atmosphere that can reach speeds in excess of 200 mph, usually occurring 6 to 9 miles above the ground. These winds often steer the movement of surface air masses and weather systems.
JET STREAM - A narrow band of high altitude winds that circles the earth in the mid and upper latitudes of the earth.
9. Jet streams are winds which have speeds of over 50 mph and maybe as high 300 plus mph.

This display is useful for observing local changes in vertical wind shear, such as backing of low-level winds, increases in speed shear, and development or evolution of nearby jet streams (including low-level jets).
