Variability of Southern Ocean Jets near Topography
The interaction of jets with topography in the Southern Ocean is investigated using 19 years of altimetry data. In particular, the ‘‘jet jumping’’ mode of variability, by which two or more jets passing close to the same topographic feature show strongly anticorrelated strengthening and weakening, is studied. Three regional case studies are described—the Southeast Indian Ridge south of Tasmania,...
متن کاملMixing of Tracers by Submesoscale Flows Formed at Wind-Driven Ocean Fronts
This project is part of the DRI on Scalable Lateral Mixing and Coherent Turbulence that aims to characterize lateral mixing in the ocean on scales of 10m-10 km, the submesoscales. Lateral mixing at the submesoscales is not accounted for in present-day ocean models. This deficiency is a potential source of error in the numerical prediction of the distribution of temperature, salt, nutrients, phy...

متن کاملInterpreting wind-driven Southern Ocean variability in a stochastic framework
A stochastic model is derived from wind stress and bottom pressure gauge data to examine the response of the Antarctic Circumpolar Current (ACC) transport to wind stress forcing. A general method is used to estimate the drift and diffusion coef cients of a continuous stationaryMarkovian system. As a rst approximation, the response of the ACC to wind stress forcing can be describedby a multiv...
متن کاملSouthern Ocean Response to Relative Velocity Wind Stress Forcing
An eddy resolving quasi-geostrophic model of the Southern Ocean coupled to a dynamic atmospheric mixed layer is used to compare the performance of two different wind stress parameterisation schemes. The first is the standard quadratic drag law based on atmospheric velocity alone, while the second (more exact) formulation is based on the difference between ocean and atmosphere velocities. The tw...
