Meander dynamics in the Antarctic Circumpolar Current ...
Meanders formed where the Antarctic Circumpolar Current (ACC) interacts with topography have been identified as dynamical hot-spots, characterised by enhanced eddy energy, momentum transfer, and cross-front exchange. However, few studies have diagnosed the dynamics of ACC standing meanders directly...

Meanders formed where the Antarctic Circumpolar Current (ACC) interacts with topography have been identified as dynamical hot-spots, characterised by enhanced eddy energy, momentum transfer, and cross-front exchange. However, few studies have diagnosed the dynamics of ACC standing meanders directly from observations. Therefore, we first use a synoptic, upper-ocean hydrographic survey and satellite altimetry to explore the momentum and vorticity balance of a Subantarctic Front standing meander, downstream of the Southeast Indian Ridge. Second, we validated the processes diagnosed in the first hydrographic survey with a high-resolution model. And finally, we applied the knowledge of the momentum and vorticity balances gained from the Subantarctic Front meander to a second, more recent hydrographic survey of a growing, unstable meander in the Polar Front. This included measurements of full depth temperature, salinity and velocityeanders formed where the Antarctic Circumpolar Current (ACC) interacts with ... |
