Revisiting the Frictional Control of the Antarctic Circumpolar Current From the Energy Diagram
Takuro Matsuta, Yuki Tanaka, Atsushi Kubokawa
The transport of the Antarctic Circumpolar Current (ACC) has been shown to increase with friction. Previous studies explained this counter-intuitive relationship called frictional…

Drag-Controlled Regime Transitions in the Eddy Saturation Mechanism of the Antarctic Circumpolar Current
Takuro Matsuta, Yuki Tanaka, Atsushi Kubokawa
Eddy saturation -- the weak sensitivity of Antarctic Circumpolar Current (ACC) transport to wind stress -- is a fundamental feature of Southern Ocean dynamics, yet the processes th…

A frictional control mechanism of circumpolar transport in barotropic reentrant channel models
Takuro Matsuta, Atsushi Kubokawa, Humio Mitsudera +1
Recent studies have reported that an increase in the bottom drag coefficient can enhance the volume transport of the Antarctic Circumpolar Current. Several mechanisms have been pro…
