Abstract: The large-scale consequences of diapycnal mixing location are explored using an idealized three-dimensional model of buoyancy-forced flow in a single hemisphere. Diapycnal mixing is most effective in supporting a strong ...

Abstract: An idealized three-dimensional model of buoyancy-driven flow in a single hemisphere is used to investigate the relationship between the meridional overturning and the efficiency by which convective mixing eliminates static ...

Abstract: Tropical cyclones instigate an isolated blast of vigorous mixing in the upper tropical oceans, stirring warm surface water with cooler water in the thermocline. Previous work suggests that the frequency, intensity, and ...

Abstract: Recent numerical experiments indicate that the rate of meridional overturning associated with North Atlantic Deep Water is partially controlled by wind stress in the Southern Ocean, where the zonal periodicity of the domain ...

Abstract: Zonal wind stress over the Southern Ocean may be responsible for a significant fraction of the meridional overturning associated with North Atlantic Deep Water. Numerical experiments by Tsujino and Suginohara imply that ...

Abstract: An idealized three-dimensional model of buoyancy-forced flow in a single hemisphere is used to investigate whether transient diapycnal mixing can sustain the meridional overturning circulation. In the annual mean, mixing ...

Abstract: The interhemispheric thermohaline circulation is examined using Rooth?s three-box ocean model, whereby overturning strength is parameterized from density differences between high-latitude boxes. Recent results with general ...

Abstract: AbstractWe present observational estimates of Ekman pumping in the Beaufort Gyre region. Averaged over the Canada Basin, the results show a 2003?14 average of 2.3 m yr?1 downward with strong seasonal and interannual ...
