23. Which of the following is a
component of upper air circulation?

"Jet streams" is the correct approach.

Explanation:

The air currents circulating at different elevations of altitudes throughout the air became recognized as the circulation of that same upper air. For those who fluctuate at the peak of the troposphere and usually blow westwards, the Jet Streams Currents at either the highest point of the troposphere appear to be polarized westwards.

So the response to the above is accurate.
