A conceptual model of oceanic heat transport in the Snowball Earth scenario [PDF]

Earth System Dynamics, 2016
Geologic evidence suggests that the Earth may have been completely covered in ice in the distant past, a state known as Snowball Earth. This is still the subject of controversy, and has been the focus of modeling work from low-dimensional models up to ...

Ocean heat transport and a climate paradox [PDF]

Atmosphere-Ocean, 2001
Abstract Paleoclimcite data indicate a climate paradox. In warmer climates the equator to pole temperature gradient is typically less than that of the current climate. However, more northward heat transport is required to maintain this weaker gradient, particularly in tropical, subtropical and midlatitude regions where the ice‐albedo feedback and polar

Artic-North Atlantic interactions and multidecadal variability of the thermohaline circulation [PDF]

, 2005
Analyses of a 500-yr control integration with the non-flux-adjusted coupled atmosphere–sea ice–ocean model ECHAM5/Max-Planck-Institute Ocean Model (MPI-OM) show pronounced multidecadal fluctuations of the Atlantic overturning circulation and the ...

Major variations in subtropical North Atlantic heat transport at short (5 day) timescales and their causes [PDF]

, 2016
Variability in the North Atlantic ocean heat transport at 26.5°N on short (5-day) timescales is identified and contrasted with different behaviour at monthly intervals using a combination of RAPID/MOCHA/WBTS measurements and the NEMO-LIM2 1/12° ocean ...

AMOC sensitivity to surface buoyancy fluxes: Stronger ocean meridional heat transport with a weaker volume transport? [PDF]

, 2016
Oceanic northward heat transport is commonly assumed to be positively correlated with the Atlantic meridional overturning circulation (AMOC). For example, in numerical “water-hosing” experiments, imposing anomalous freshwater fluxes in the northern ...

Influence of Sea-Ice Anomalies on Antarctic Precipitation Using Source Attribution in the Community Earth System Model [PDF]

, 2020
We conduct sensitivity experiments using a general circulation model that has an explicit water source tagging capability forced by prescribed composites of pre-industrial sea-ice concentrations (SICs) and corresponding sea surface temperatures (SSTs) to

The Coherence of the Oceanic Heat Transport Through the Nordic Seas: Oceanic Heat Budget and Interannual Variability [PDF]

Russian Journal of Earth Sciences, 2020
The Atlantic Water is the main source of heat and salt in the Arctic. Properties of the Atlantic Water inflow regionally affect sea ice extent and deep water formation rate. The Atlantic Water heat transported into the Nordic Seas has a significant impact on the local climate and is investigated here along with its inter-annual variability.

Mid-pliocene Atlantic Meridional Overturning Circulation not unlike modern [PDF]

Climate of the Past, 2013
In the Pliocene Model Intercomparison Project (PlioMIP), eight state-of-the-art coupled climate models have simulated the mid-Pliocene warm period (mPWP, 3.264 to 3.025 Ma).

Changes in ocean vertical heat transport with global warming [PDF]

, 2015
Heat transport between the surface and deep ocean strongly influences transient climate change. Mechanisms setting this transport are investigated using coupled climate models and by projecting ocean circulation into the temperature-depth diagram.

Disentangling the Coupled Atmosphere‐Ocean‐Ice Interactions Driving Arctic Sea Ice Response to CO2 Increases

Journal of Advances in Modeling Earth Systems, 2020
A novel decomposition of the ocean heat energy that contributes to sea ice melt and growth (ocean‐ice and frazil heat) into components that are driven by surface heat flux and ocean circulation changes is used to isolate the evolving roles of the ...
