Definition: Jet Stream |
Jet StreamNoun1. A high-speed high-altitude airstream blowing from west to east near the top of the troposphere; has important effects of the formation of weather fronts. Source: WordNet 1.7.1 Copyright © 2001 by Princeton University. All rights reserved. |
| Domain | Definition |
Aerospace | 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. See jetstream, note. (references) |
Geography | Flat tubular current of air, quasi-horizontal, generally near the tropopause, whose axis is along a line of maximum speed and which is characterized. . . by great speeds. . and. . also by strong tranverse grad ients of speed. Source: European Union. (references) |
Mechanical Engineering | High velocity gas flow discharged from nozzle. Source: European Union. (references) |
| Quasi-horizontal wind exceeding 148km/h in warm air at sharp boundary with cold, high troposphere or stratosphere, mid latitudes, predominantly westerly. Source: European Union. (references) | |
Science | 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. The jet streams may be several hundred miles across and 1-2 miles deep at an altitude of 8-12 miles. They generally move west to east, and are strongest in the winter with core wind speeds as high as 250 mph. Changes in the jet stream indicate changes in the motion of the atmosphere and weather. (references) |
Weather | 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. General weather patterns (hot/cold, wet/dry) are related closely to the position, strength and orientation of the jet stream (or jet streams). A jet stream at low levels is known as a low-level jet.

(From Wikipedia, the free Encyclopedia)
Jet streams are fast flowing, confined air currents found in the atmosphere at around 12 km above the surface of the Earth (just under the tropopause). They form at the boundaries of adjacent air masses with significant differences in temperature, such as of the polar region and the warmer air to the south (the meridional temperature gradient). Because of the effect of the Earth's rotation the streams flow west to east, propagating in a serpentine or wave-like manner at lower speeds than that of the actual wind within the flow.
There are two main jet streams at polar latitudes, one in each hemisphere, and two lesser streams closer to the equator. In the northern hemisphere the streams are most commonly found between latitude 30° - 70° for the polar jet stream and between latitude 20° - 50° for the other. The wind speeds vary according to the temperature gradient, they average 55 km/h in summer and 120 km/h in winter, although speeds of over 400 km/h are known. Technically the wind speed has to be higher than 90 km/h to be called a jet stream.
The location of the jet stream is an extremely important datum for airlines. In the United States, for example, the time needed to fly east/west across the US can be increased or decreased by about 30 minutes if the airplane can fly with or against the jet stream.
The first practical use of jet streams was presumably the Japanese fire balloon atacks on the American mainland during WWII.
