The importance of Brewer–Dobson circulation in the stratosphere is most related to what?
Answer and explanation
Correct answer: Global transport of stratospheric air and ozone
Brewer–Dobson circulation describes the large-scale overturning movement of stratospheric air: air generally rises in the tropics, moves poleward, and descends at higher latitudes. This circulation redistributes trace gases, especially ozone and substances involved in ozone chemistry, across the stratosphere. Therefore option B is correct. It does not stop ordinary tropospheric rain, move the exosphere to the ground, or transport seawater into the mesosphere; those choices confuse atmospheric circulation with unrelated processes.
