Southern Ocean heat and momentum uptake are sensitive to the vertical resolution at the ocean surface [PDF]
Ocean Modelling, 2019 Abstract The Southern Ocean plays a leading oceanic role in Earth’s changing climate, accommodating over two thirds of the excess anthropogenic heat to date. In spite of this, climate and ocean models exhibit substantial variability in Southern Ocean heat uptake and storage, reflecting the modelling challenges of representing the responsible ...

The magnitudes and timescales of global mean surface temperature feedbacks in climate models [PDF]
Earth System Dynamics, 2011 Because of the fundamental role feedbacks play in determining the response of surface temperature to perturbations in radiative forcing, it is important we understand the dynamic characteristics of these feedbacks.

The Deep-Ocean Heat Uptake in Transient Climate Change [PDF]
Journal of Climate, 2003 Abstract The deep-ocean heat uptake (DOHU) in transient climate changes is studied using an ocean general circulation model (OGCM) and its adjoint. The model configuration consists of idealized Pacific and Atlantic basins. The model is forced with the anomalies of surface heat and freshwater fluxes from a global warming scenario with a ...

A Conceptual Model of Ocean Heat Uptake under Climate Change [PDF]
Journal of Climate, 2014 Abstract A conceptual model of ocean heat uptake is developed as a multilayer generalization of Gnanadesikan. The roles of Southern Ocean Ekman and eddy transports, North Atlantic Deep Water (NADW) formation, and diapycnal mixing in controlling ocean stratification and transient heat uptake are investigated under climate change scenarios,

Stratification and overturning circulation are intertwined controls on ocean heat uptake efficiency in climate models [PDF]
Ocean ScienceThe global ocean takes up over 90 % of the excess heat added to the climate system due to anthropogenic emissions, thereby buffering climate change at Earth's surface. A key metric for quantifying the role of the oceanic processes removing this heat from

Global Warming Pattern Formation: The Role of Ocean Heat Uptake
Journal of Climate, 2022 Abstract This study investigates the formation mechanism of the ocean surface warming pattern in response to a doubling CO2 with a focus on the role of ocean heat uptake (or ocean surface heat flux change, ΔQnet). We demonstrate that the transient patterns of surface warming and rainfall change simulated by the dynamic ocean–atmosphere coupled model ...

Drivers of uncertainty in simulated ocean circulation and heat uptake [PDF]
Geophysical Research Letters, 2017 AbstractThe impact of uncertainties in air‐sea fluxes and ocean model parameters on the ocean circulation and ocean heat uptake (OHU) is assessed in a novel modeling framework. We use an ocean‐only model forced with the simulated sea surface fields of the CMIP5 climate models.

The Effects of Ocean Heat Uptake on Transient Climate Sensitivity [PDF]
Current Climate Change Reports, 2016 Transient climate sensitivity tends to increase on multiple timescales in climate models subject to an abrupt CO2 increase. The interdependence of radiative and ocean heat uptake processes governing this increase are reviewed. Heat uptake tends to be spatially localized to the subpolar oceans, and this pattern emerges rapidly from an initially uniform ...

Geophysical Research Letters, 2019 Mixing of the upper ocean by the wind field associated with tropical cyclones (TCs) creates observable cold wakes in sea surface temperature and may potentially influence ocean heat uptake. The relationship between cold wake size and storm size, however,

Ocean Heat Uptake in Eddying and Non-Eddying Ocean Circulation Models in a Warming Climate
Journal of Physical Oceanography, 2013 Abstract Ocean heat uptake is explored with non-eddying (2°), eddy-permitting (0.25°), and eddy-resolving (0.125°) ocean circulation models in a domain representing the Atlantic basin connected to a southern circumpolar channel with a flat bottom.
