Jet streams are fast flowing, narrow air currents found in the atmospheres of some planets, including Earth. The main jet streams are located near the altitude of the tropopause, the transition between the troposphere and the stratosphere (where temperature increases with altitude). The major jet streams on Earth are westerly winds (flowing west t...

A comparatively narrow current of air that moves around the northern and southern hemispheres of the Earth in wavelike patterns. It can be likened to a river of wind moving at high speed. The jet stream varies from about 100 to 400 miles (161 to 644 km) wide and 1 to 3 miles (1.6 to 4.8 km) thick. I...

A narrow band of winds blowing high in the troposphere at speeds in excess of 60 miles per hour but can reach speeds in excess of 300 miles per hour. Typically thousands of kilometres long, hundreds of kilometres wide and a few kilometres deep. They are closely associated with the weather systems in temperate latitudes.
