In the upper layers of the South Indian Ocean, three anomalous currents are observed: The South Indian Ocean Countercurrent, the Leeuwin Current and the Indonesian Throughflow. Using two models of different complexity, we show how these three currents can be dynamically connected, unravelling the large-scale connectivity. Further, we produce a conceptual theory of how this current system follows an idealized pattern of wind stress and buoyancy forcing.
