Why is vertical mixing weaker in the stratosphere than in the troposphere?
Answer and explanation
Correct answer: Upward increase in temperature makes the air stable
The correct answer is A. In the stratosphere, temperature generally increases with height because ozone absorbs solar ultraviolet radiation. A warmer layer above a cooler layer creates stable stratification, so a rising air parcel becomes cooler than its surroundings and tends to sink back. This suppresses convection and vertical mixing. Surface friction and rising rain clouds are mainly tropospheric effects.
