By which clue can the stratopause be identified in a thermal profile?
Answer and explanation
Correct answer: Upper end of stratospheric temperature increase
In a vertical temperature profile, temperature generally increases through the stratosphere because ozone absorbs ultraviolet radiation. The stratopause is the transition at the top of that layer, where this increasing temperature trend ends and the mesosphere begins, with temperature again tending to decrease upward. Thus option A gives the diagnostic clue. Rainfall belongs mainly to the troposphere, gas escape is associated with the exosphere, and sea-level pressure is not a boundary marker.
