Meridional Density Gradients Do Not Control the Atlantic Overturning Circulation
A wide body of modeling and theoretical scaling studies support the concept that changes to the Atlantic meridional overturning circulation (AMOC), whether forced by winds or buoyancy fluxes, can be understood in terms of a simple causative relation between the AMOC and an appropriately defined meridional density gradient (MDG). The MDG is supposed to translate directly into a meridional pressu...
متن کاملAtlantic 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 کاملActive Pacific meridional overturning circulation (PMOC) during the warm Pliocene
An essential element of modern ocean circulation and climate is the Atlantic meridional overturning circulation (AMOC), which includes deep-water formation in the subarctic North Atlantic. However, a comparable overturning circulation is absent in the Pacific, the world's largest ocean, where relatively fresh surface waters inhibit North Pacific deep convection. We present complementary measure...
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...
