Approximate Solution of the Stommel Model: Sverdrup Balance
The Sverdrup transport and the implied western boundary currents in the oceans corresponding to the annual mean wind-stress field if the Sverdrup transport is required to satisfy the normal-flow condition on oceanic eastern boundaries
The figure represent the volume transports in Sverdrups (millions of m$^3$ s$^{-1}$)
