Short summary
The climatology of the Brewer–Dobson circulation and the potential contribution of gravity waves (GWs) are examined using four modern reanalysis datasets for the annual mean and each season. In this study, unresolved waves are designated as GWs. GWs are essential to determine the high-latitude extension and the turn-around latitude except in summer, although their contribution to the upward mass flux is relatively small. Plausible deficiencies of the current GW parameterizations are discussed.
