Detailed explanation-1: -Jet Streams are high velocity winds that blow in the upper troposphere at an altitude of around 12, 000 metres. These winds are faster than surface winds as there are no obstacles in the upper troposphere. The speed can vary from 110 to 184 km/h in winter.
Detailed explanation-2: -A jet stream is a type of air current that forms high in the atmosphere. On average, jet streams move at about 110 miles per hour. But dramatic temperature differences between the warm and cool air masses can cause jet streams to move at much higher speeds-250 miles per hour or faster.
Detailed explanation-3: -The Jet Stream is a geostrophic wind blowing horizontally through the upper layers of the troposphere, generally, from west to east, it is also known as high altitude westerly winds which blow at an altitude of 20, 000-50, 000 feet.
