The occurrence of jet streams near the tropopause is most related to what?
Answer and explanation
Correct answer: Strong temperature and pressure gradients in the upper troposphere
The governing concept is that strong horizontal temperature differences create pressure-gradient forces and powerful upper-air winds. Near the tropopause, contrasts between adjoining air masses help produce narrow, fast-moving jet streams, especially in the upper troposphere. Thus option A is correct. Hydrogen in the exosphere, meteors burning in the mesosphere, and rainfall formation in the stratosphere do not explain jet-stream formation or location.
