Advective Transport Between the Stratosphere and Mesosphere
Original language description
The Brewer-Dobson circulation (BDC) characterizes the large-scale meridional overturning masscirculation influencing the composition of the whole middle atmosphere. The BDC consists of two separateparts-a shallow branch in the lower stratosphere and a deep branch higher in the middle atmosphere. Climatemodels robustly project the advective BDC part to accelerate due to greenhouse gas-induced climate change andthis acceleration strongly influences middle atmospheric chemistry and physics in the projections. A prominentquantity that is being studied as a proxy for advective BDC changes is the net tropical upwelling across pressurelevels, particularly in the lower stratosphere. The upper branch of the BDC has received considerably lessresearch attention than its shallow part, although, together with the mean mesospheric pole-to-pole circulation,it couples the stratosphere and mesosphere and is responsible for a large portion of the interhemispherictransport in the middle atmosphere. Aiming to fill this gap, we here study climatology and trends in advectivemass transport across the stratopause. Results based on the analysis of seven CCMI models includequantification of the climatological cross-stratopause advective transport, characterization of its interannualvariability and long-term trend as well as detailed analysis of inter-model differences using a noveldecomposition methodology. Our results demonstrate that the changes in circulation speed as well as changes inhorizontal and vertical structure in the upper stratosphere and mesosphere jointly shape the projected increasingadvective mass flux across the stratopause due to increasing greenhouse-gas emissions.
