Question

Which one of the following statements best describes “jet streams”?

• A. Wind system with seas and reversal of direction
• B. Wind blowing from subtropical high-pressure belts towards the tropical low-pressure belts
• C. Narrow meandering bands of winds which blow in mid-latitude near the tropopause and encircle the globe
• D. Winds blowing from the tropical high-pressure belts towards the equatorial low-pressure belts.

Answer 1

The correct option is C Narrow meandering bands of winds which blow in mid-latitude near the tropopause and encircle the globe

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.
