Dynamics of global ocean heat transport variability
A state-of-the-art, high-resolution ocean general circulation model is used to estimate the time-dependent global ocean heat transport and investigate its dynamics. The north-south heat transport is the prime manifestation of the ocean’s role in global climate, but understanding of its variability …

Dependence of tropical precipitation on changes in cross-equatorial atmosphere and ocean heat transport in global warming simulations
… decline) results in a greater net influx of heat into one hemisphere the Hadley cells will shift across the equator to transport heat from the warmer to the cooler hemisphere resulting in a shift of the annual mean location of the ITCZ. Shifts in the annual mean location of the ITCZ can …

The effect of changing topological constraints on poleward ocean heat transport induced by plate tectonics over the last 600 million years
… 600 Ma. Different topological constraints on the oceans may affect their ability to transport heat poleward and change the equilibrium pole-equator temperature of Earth. An ocean model was run for three simple continental geometries to determine the effect of land distribution on the heat …

The influence of heat transport on Arctic amplification
… versus remote factors, such as changes in heat transport from the midlatitudes. This thesis focuses mainly on the role of poleward heat transport on Arctic amplification. Most of the previous studies on this topic have defined ocean heat transport as the zonally averaged ocean heat …

Coupling of the intertropical convergence zone and the Hadley cells to the ocean's circulation
… and shift, for example, into the hemisphere heated most strongly by radiation and surface heat fluxes. By redistributing heat around the globe, the ocean circulation plays an important role in the atmosphere's energy balance and is a potentially strong control on the region of intense …

The Role of diapycnal mixing in coupled atmosphere-ocean general circulation models
The value of ocean diapycnal diffusivity (v) sets the rate at which dense bottom water can be mixed<br/>up through the stratified water column and thus plays an important role in the meridional overturning<br/>circulation (MOC). Previous idealised experiments and simplified theory suggest that the …

Oceanic control of the sea ice edge and multiple equilibria in the climate system
I study fundamental mechanisms of atmosphere-ocean-sea ice interaction. Hierarchies of idealized models are invoked to argue that multiple equilibria and abrupt change are robust features of the climate system. The main finding is that meridional structure in poleward oceanic energy transport, …

Decadal variability of the Atlantic Meridional Overturning Circulation
In the mean, the Atlantic Ocean transports 1 to 1.5 PW of heat northward, and estimates suggest that 60% of this heat transport is associated with a circulation that reaches the cold waters of the abyss. Due to the role of the Atlantic Meridional Overturning Circulation (AMOC) in ocean heat …
