Ocean Science Southern Ocean overturning across streamlines in an eddying simulation of the Antarctic Circumpolar Current
Abstract. An eddying global model is used to study the characteristics of the Antarctic Circumpolar Current (ACC) in a streamline-following framework. Previous model-based estimates of the meridional circulation were calculated using zonal averages: this method leads to a counter-intuitive poleward...
