Atlantic Dominance of the Meridional Overturning Circulation
North Atlantic (NA) deep-water formation and the resulting Atlantic meridional overturning cell is generally regarded as the primary feature of the global overturning circulation and is believed to be a result of the geometry of the continents. Here, instead, the overturning is viewed as a global energy–driven system and the robustness of NA dominance is investigated within this framework. Usin...
متن کاملChanges in the Atlantic Meridional Overturning Circulation
Introduction: the concept of the MOC Climate models project a slow down of the Atlantic Meridional Overturning Circulation (MOC) in the twenty-first century. This slow down is expected to affect climate over Europe. In particular, it damps the temperature rise due to the emission of greenhouse gases. The MOC is associated with the thermohaline circulation (ThC), which is the large-scale ocean c...
متن کاملDissolved Organic Carbon in the North Atlantic Meridional Overturning Circulation
The quantitative role of the Atlantic Meridional Overturning Circulation (AMOC) in dissolved organic carbon (DOC) export is evaluated by combining DOC measurements with observed water mass transports. In the eastern subpolar North Atlantic, both upper and lower limbs of the AMOC transport high-DOC waters. Deep water formation that connects the two limbs of the AMOC results in a high downward ex...
متن کاملInterdecadal North-Atlantic Meridional Overturning Circulation Variability in EC-EARTH
Received: date / Accepted: date Abstract The pre-industrial run of the newly developed EC-EARTH model fea1 tures marked interdecadal variability with a dominant time-scale of 50-60 yr. 2 An oscillation of approximately 2 Sverdrup (1 Sv = 10 ms) is identified, 3 which manifests itself as a monopole causing the overturning to simultaneously 4 strengthen(/weaken) and deepen(/shallow) as a whole wi...
متن کاملOn the Driving Processes of the Atlantic Meridional Overturning Circulation
[1] Because of its relevance for the global climate the Atlantic meridional overturning circulation (AMOC) has been a major research focus for many years. Yet the question of which physical mechanisms ultimately drive the AMOC, in the sense of providing its energy supply, remains a matter of controversy. Here we review both observational data and model results concerning the two main candidates...
