Difference between the North Atlantic and Pacific meridional overturning circulation in response to the uplift of the Tibetan Plateau [PDF]

Climate of the Past, 2018
The role of the Tibetan Plateau (TP) in maintaining the large-scale overturning circulation in the Atlantic and Pacific is investigated using a coupled atmosphere–ocean model.

An indicator of the multiple equilibria regime of the Atlantic meridional overturning circulation [PDF]

, 2010
Recent model results have suggested that there may be a scalar indicator ? monitoring whether the Atlantic meridional overturning circulation (MOC) is in a multiple equilibrium regime. The quantity ?

Stability of the Atlantic meridional overturning circulation: A model intercomparison [PDF]

Geophysical Research Letters, 2012
The evolution of the Atlantic Meridional Overturning Circulation (MOC) in 30 models of varying complexity is examined under four distinct Representative Concentration Pathways. The models include 25 Atmosphere‐Ocean General Circulation Models (AOGCMs) or Earth System Models (ESMs) that submitted simulations in support of the 5th phase of the Coupled ...

Optimal surface salinity perturbations of the meridional overturning and heat transport in a global ocean general circulation model [PDF]

, 2008
Recent observations and modeling studies have stressed the influence of surface salinity perturbations on the North Atlantic circulation over the past few decades.

Arctic closure as a trigger for Atlantic overturning at the Eocene-Oligocene Transition

Nature Communications, 2019
Proxies of deep circulation suggest that the onset or strengthening of the Atlantic meridional overturning circulation occurred at the Eocene-Oligocene Transition. The authors show, using a paleoclimate model of the late Eocene, that a shift from Pacific

Interior pathways of the North Atlantic meridional overturning circulation [PDF]

Nature, 2009
To understand how our global climate will change in response to natural and anthropogenic forcing, it is essential to determine how quickly and by what pathways climate change signals are transported throughout the global ocean, a vast reservoir for heat and carbon dioxide. Labrador Sea Water (LSW), formed by open ocean convection in the subpolar North

Subpolar North Atlantic western boundary density anomalies and the Meridional Overturning Circulation

Nature Communications, 2021
Western boundary current variability in the subpolar North Atlantic is thought to reflect interior convection changes and determine Atlantic Meridional Overturning Circulation variability.

A numerical model study of the effects of interannual timescale wave propagation on the predictability of the Atlantic meridional overturning circulation [PDF]

, 2013
We investigate processes leading to uncertainty in forecasts of the Atlantic meridional overturning circulation (AMOC). A climate model is used to supply initial conditions for ensemble simulations in which members initially have identical ocean states ...

Extreme deepening of the Atlantic overturning circulation during deglaciation [PDF]

, 2010
Glacial terminations during the late Pleistocene epoch are associated with changes in insolation. They are also punctuated by millennial-scale climate shifts, characterized by a weakening and subsequent strengthening of the Atlantic meridional ...
