what is jet stream
Answers
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. Their paths typically have a meandering shape. Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including opposite to the direction of the remainder of the jet.
Jet streams are the product of two factors: the atmospheric heating by solar radiation that produces the large-scale Polar, Ferrel, and Hadley circulation cells, and the action of the Coriolis force acting on those moving masses. The Coriolis force is caused by the planet's rotation on its axis. On other planets, internal heat rather than solar heating drives their jet streams. The Polar jet stream forms near the interface of the Polar and Ferrel circulation cells; the subtropical jet forms near the boundary of the Ferrel and Hadley circulation cells.

Hey there!
Jet Streams:
Jet Streams are fast flowing narrow air currents in the upper atmosphere or in troposphere of some planets including earth.
Importance or Effect of Jet Streams:
Jet Streams changes the pressure conditions in the upper atmosphere which diverts the winds resulting into changed pattern of rain.
