Latitudinal dependence of Atlantic meridional overturning circulation (AMOC) variations
[1] AMOC variations are often thought to propagate with the Kelvin wave speed, resulting in a short time lead between high and low latitudes AMOC variations. However as shown in this paper using a coupled climate model (GFDL CM2.1), with the existence of interior pathways of North Atlantic Deep Water (NADW) from Flemish Cap to Cape Hatteras as that observed recently, AMOCvariations estimated in...
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 کاملNorthward intensification of anthropogenically forced changes in the Atlantic meridional overturning circulation (AMOC)
[1] Extensive modeling studies show that changes in the anthropogenic forcing due to increasing greenhouse gases might lead to a slowdown of the Atlantic meridional overturning circulation (AMOC) in the 21st century, but the AMOC weakening estimated in most previous modeling studies is in depth space. Using a coupled ocean atmosphere model (GFDL CM2.1), this paper shows that in density space, t...
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 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...
