Atlantic meridional ocean heat transport at 26° N: impact on subtropical ocean heat content variability [PDF]

Ocean Science, 2013
Local climate is significantly affected by changes in the oceanic heat content on a range of timescales. This variability is driven by heat fluxes from both the atmosphere and the ocean.

Drivers of the evolution and amplitude of African Humid Periods

Communications Earth & Environment, 2021
A strengthening of the Atlantic Meridional Overturning Circulation was the main driver of the abrupt initiation of African Humid Periods during the last two deglaciations, according to transient simulations performed using an Earth system model.

Melancholia states of the Atlantic Meridional Overturning Circulation

Physical Review Fluids
The Atlantic Meridional Overturning Circulation (AMOC) is a much studied component of the climate system, because its suspected multistability is associated with tipping behavior yielding potentially large regional and global climatic impacts. In this paper we investigate the global stability properties of the system using an ocean general circulation ...

Monitoring the Atlantic Meridional Overturning Circulation at 26.5°N: RAPID-WATCH [PDF]

, 2008
The Atlantic Meridional Overturning Circulation (AMOC) at 26.5°N carries a northward heat flux of 1.3 PW. Northward of 26.5°N over the Gulf Stream and its extension much of this heat is transferred to the atmosphere and subsequently is responsible for ...

Atlantic Meridional Overturning Circulation slowdown modulates wind-driven circulations in a warmer climate

Communications Earth & Environment
Wind-driven and thermohaline circulations, two major components of global large-scale ocean circulations, are intrinsically related. As part of the thermohaline circulation, the Atlantic Meridional Overturning Circulation has been observed and is ...

Possibility for strong northern hemisphere high-latitude cooling under negative emissions

Nature Communications, 2022
A strong decrease or collapse of the Atlantic Meridional Overturning Circulation would cool down the northern high latitudes. This study reveals the possibility that such cooling could be amplified under deliberate CO2 removal from the atmosphere.

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Observed and simulated variability of the AMOC at 26°N and 41°N [PDF]

, 2013
Timeseries of the observational estimate of the Atlantic meridional overturning circulation (AMOC) have recently become available, but so far no contemporaneous relation has been documented between them. Here, we analyze the variability of the 26°N RAPID

The stability of an evolving Atlantic meridional overturning circulation [PDF]

Geophysical Research Letters, 2013
In this study, we propose a generalized stability indicator, L, for a slowly evolving and quasi‐steady Atlantic meridional overturning circulation (AMOC), which represents a feedback related to the AMOC and its associated freshwater transport within the Atlantic basin.

Antarctic meltwater reduces the Atlantic meridional overturning circulation through oceanic freshwater transport and atmospheric teleconnections

Communications Earth & Environment
The Atlantic meridional overturning circulation is an important component of the climate system because of its role in the heat transport. Its strength is sensitive to the surface density but mechanisms of the effect of Southern Ocean freshwater ...
