What are fast moving winds blowing in a narrow zone in the upper atmosphere called?
A
Seasonal Reversal winds
B
Jet Streams
C
Freezing cold winds
D
Southeast trade winds
Explanation: 

Detailed explanation-1: -Jet streams are geostrophic winds that form near the boundaries of air masses with different temperatures and humidity. The rotation of the Earth and its uneven heating by the sun also contribute to the formation of high-altitude jet streams. These strong, fast winds in the upper atmosphere can blow 480 kph (298 mph).

Detailed explanation-2: -What is a Jet Stream? The Jet Stream is a geostrophic wind blowing horizontally through the upper layers of the troposphere, generally from west to east, at an altitude of 20, 000-50, 000 feet. Jet Streams develop where air masses of differing temperatures meet.

Detailed explanation-3: -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.

Detailed explanation-4: -Jet streams are bands of strong wind that generally blow from west to east all across the globe. These are relatively narrow bands of strong wind in the upper levels of the atmosphere.

Detailed explanation-5: -The jet stream flows high overhead and causes changes in the wind and pressure at that level. This affects things nearer the surface, such as areas of high and low pressure, and therefore helps shape the weather we see. Sometimes, like in a fast-moving river, the jet stream’s movement is very straight and smooth.
