Jet stream. Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Their paths typically have a meandering shape. Specifically, the jet stream is caused by the meeting of air masses just under the tropopause where winds are the strongest. This illustrates the importance of region when analyzing zonal wind responses to surface warming.
