Vertical heat transport in eddying ocean models [PDF]

Geophysical Research Letters, 2008
The effect of mesoscale eddies on the vertical heat transport of the ocean is examined using two eddy‐resolving numerical models. The global heat transport by the mean flow and diffusion are both downwards and are balanced by an upward eddy heat flux. Mean and eddy advective heat fluxes dominate the subpolar regions, while diffusive flux is important ...

Influence of the Multidecadal Atlantic Meridional Overturning Circulation Variability on European Climate [PDF]

, 2006
The influence of the natural multidecadal variability of the Atlantic meridional overturning circulation (MOC) on European climate is investigated using a simulation with the coupled atmosphere–ocean general circulation model ECHAM5/Max Planck Institute ...

Beyond the bipolar seesaw: toward a process understanding of interhemispheric coupling [PDF]

, 2018
The thermal bipolar ocean seesaw hypothesis was advanced by Stocker and Johnsen (2003) as the ‘simplest possible thermodynamic model’ to explain the time relationship between Dansgaard–Oeschger (DO) and Antarctic Isotope Maxima (AIM) events.

Biased thermohaline exchanges with the Arctic across the Iceland–Faroe Ridge in ocean climate models [PDF]

Ocean Science, 2016
The northern limb of the Atlantic thermohaline circulation and its transport of heat and salt towards the Arctic strongly modulate the climate of the Northern Hemisphere.

Climate Sensitivity to Changes in Ocean Heat Transport

Journal of Climate, 2011
Using an atmospheric general circulation model coupled to a slab ocean, the effects of ocean heat transport (OHT) on climate are studied by prescribing OHT from 0 to 2 times the present-day values. In agreement with previous studies, an increase in OHT from zero to present-day conditions warms the climate by decreasing the albedo due to reduced sea ...

Neutron star oceans: Instability, mixing, and heat transport [PDF]

Astronomy & Astrophysics, 2004
Summary: Stability of the ocean of magnetic neutron stars is considered. We argued that the ocean is unstable if the temperature varies along the surface. The instability grows on a time scale \(0.1-100\)\,s depending on the lengthscale of perturbations and generates a weak turbulence.

Gateway-driven weakening of ocean gyres leads to Southern Ocean cooling

Nature Communications, 2021
The role of Southern Ocean gateways contributing to the Eocene-Oligocene climate transition is still debated. Here, the authors present high-resolution ocean simulations to show that gateways opening led to a reorganization of ocean circulation, heat ...

Poleward heat transport in the ocean.

Tellus A, 1991
The large-scale transport of heat and carbon by the ocean circulation play an important role in the Earth's climate. Progress in developing realistic models of this process is reviewed. Sufficient numerical experiments have been carried out to indicate the role of subgrid scale mixing of temperature and salinity in the transport behavior of the models.

Poleward Heat Transport in a Barotropic Ocean Model

Journal of Physical Oceanography, 1995
Abstract A barotropic ocean circulation model coupled to a mixed-layer temperature equation is used to study the poleward heat transport by the horizontal wind-driven ocean currents. Through scaling analyses, two different regimes of the heat transport are found, characterized by λ→∞ and λ→0, respectively, where λ is the ratio between the ocean ...
