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.
A: The jet stream is often described as a fast-moving river of air that forms along the boundaries of the cold and warm air masses that surround the Earth. The greater the temperature contrast, the stronger the jet stream. Low-pressure areas (storms) form along these boundaries and are often near the jet streams. These jets and lows are really waves in our ocean of air and like other waves can interact, amplify and strengthen. Storms don't create the jet stream, but a strong jet stream can help create a very powerful storm.
