 Brewer–Dobson circulation

The wave-driven mean stratospheric circulation with tropical ascent and extratropical descent. Changes in wave propagation and momentum deposition can alter its strength and transport times. Its response redistributes ozone and trace gases; local chemistry and transport must be considered together.

Brewer–Dobson circulation is a large-scale atmospheric circulation pattern in the stratosphere, primarily occurring in the tropical regions and influencing the distribution of ozone in the atmosphere. This circulation is named after two scientists, Sir Gordon Brewer and John Dobson, who contributed to the understanding of stratospheric processes.
