Jet stream is the term used for very fast air currents that flow at high altitudes, even above the regions where airplanes fly. These winds generally blow from west to east and can be thought of as long, narrow rivers of air encircling the Earth. Where Do They Form? Jet streams form in the upper part of the troposphere, the lowest layer of the atmosphere, at altitudes of approximately 10 to 15 kilometers. They are typically found in the mid-latitudes of both the Northern and Southern Hemispheres
