RISMultidecadal to Centennial Variability of the AMOC: HadCM3 and a Perturbed Physics Ensemble
Publisher: American Meteorological Society
Abstract: ultidecadal to centennial variability of the Atlantic meridional overturning circulation (AMOC) is investigated in a multi-thousand-year simulation of the third version of the Hadley Centre Coupled Model (HadCM3) and in ...
A Multimodel Study of Sea Surface Temperature and Subsurface Density Fingerprints of the Atlantic Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: he Atlantic meridional overturning circulation (AMOC) is an important component of the North Atlantic climate system. Here, simulations from 10 coupled climate models are used to calculate patterns of sea surface temperature ...
Topographic Control of Basin and Channel Flows: The Role of Bottom Pressure Torques and Friction
Publisher: American Meteorological Society
Abstract: The topographical control of western boundary currents within a basin and zonal jets in a channel is investigated in terms of the potential vorticity (PV) and barotropic vorticity (BV: the curl of the depth-integrated ...
Mechanisms of Low-Frequency Variability in North Atlantic Ocean Heat Transport and AMOC

Locations and mechanisms of ocean ventilation in the high-latitude North Atlantic in an eddy-permitting ocean model
Publisher: American Meteorological Society
Abstract: A substantial fraction of the deep ocean is ventilated in the high-latitude North Atlantic. Consequently, the region plays a crucial role in transient climate change through the uptake of carbon dioxide and heat. However, ...
Improving Oceanic Overflow Representation in Climate Models: The Gravity Current Entrainment Climate Process Team
Publisher: American Meteorological Society
Abstract: Oceanic overflows are bottom-trapped density currents originating in semienclosed basins, such as the Nordic seas, or on continental shelves, such as the Antarctic shelf. Overflows are the source of most of the abyssal ...
