Question

What are jet streams? ​

Answer 1

Answer:

Jet streams are streams of air that flow horizontally through the upper layers of the troposphere from west to east direction. They flow at an altitude of 20,000-50,000 feet.

Answer 2

Answer:

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air. ... The earth's rotation is responsible for the jet stream as well.
