WebApr 2, 2015 · The spatial-temporal distribution characters of trace gases in the stratosphere and troposphere are affected by the Brewer-Dobson (BD) circulation. Understanding the distribution characters of the BD circulation is very important for further studying the influence of stratosphere and troposphere exchange and forecasting the global climate … Brewer–Dobson circulation refers to the global atmospheric circulation pattern of tropical tropospheric air rising into the stratosphere and then moving poleward as it descends. The basics of the circulation were first proposed by Gordon Dobson and Alan Brewer. The term "Brewer–Dobson circulation" was first … See more Brewer–Dobson circulation is driven by planetary scale atmospheric waves, namely Rossby waves, with results in westward drag and therefore poleward pumping action to conserve angular momentum See more Because it moves air into and out of the stratosphere, Brewer–Dobson circulation determines the mean age and residence time of … See more • Chapman cycle • Dobson unit See more Interest in Brewer–Dobson circulation has increased in the 21st century due to predictions of general circulation models and chemistry-climate models that the circulation will accelerate due to greenhouse-gas induced climate change.
