The fast blowing winds of steady velocity, in a narrow zone of upper atmosphere is called jet streams. It helps in distributing the monsoon rainfall all over the India. the westerly flows are responsible for the western disturbances experienced in the north and the north - western parts of the country. the easterly jet streams cause tropical depressions during the monsoon as well as October-november months

The jet stream consists of ribbons of very strong winds which move weather systems around the globe. Jet streams are found 9-16 km above the surface of the Earth, just below the tropopause, and can reach speeds of 200 mph.

Jet streams are currents of air high above the Earth. They move eastward at altitudes of about 8 to 15 kilometers (5 to 9 miles). They form where large temperature differences exist in the atmosphere.
An air current is a flowing movement of air within a larger body of air. Air currents flow in the atmosphere, the layers of air surrounding the Earth. They form because the sun heats the Earth unevenly. As the sun beams down on the Earth, it warms some areas, particularly the tropics, more than others, such as the poles. As the Earth is heated, it warms the air just above it. The warmed air expands and becomes lighter than the surrounding air. It rises, creating a warm air current. Cooler, heavier air then pushes in to replace the warm air, forming a cool air current. Jet streams are air currents in the highest part of the atmosphere.
