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.
The Jet Stream map shows today's high wind speed levels and jetstream directions. Jet streams are fast flowing, relatively narrow air currents found in the atmosphere around 10 kilometers above the surface of the Earth. They form at the boundaries of adjacent air masses with significant differences in temperature, such as the polar region and the warmer air to the south.
