The occurrence of jet streams near the tropopause is best understood by which combined effect?
Answer and explanation
Correct answer: Temperature and pressure gradients in the upper troposphere
Jet streams are narrow bands of very fast winds near the tropopause. The governing principle is the pressure-gradient force, strengthened by strong horizontal temperature contrasts between air masses; Earth’s rotation then deflects the flow through the Coriolis effect. Option A gives the relevant combined thermal and pressure-gradient cause. Gas escape, mesospheric ozone, and stratospheric rain do not generate these upper-tropospheric wind belts.
