The solutions of ( 5 ) with boundary condition that \ psi be constant on the coastlines, and for different values of \ alpha, emphasize the role of the variation of the Coriolis parameter with latitude in inciting the strengthening of western boundary currents.

This prohibited the application of his theory to the western boundary currents, since some form of dissipative effect ( bottom Ekman layer ) would be later shown to be necessary to predict a closed circulation for an entire ocean basin and to counteract the wind-driven flow.

The typical water volume transported by the Somali Current amounts to "'37 + /-5 Sv "'( during mid-September ), making the current circulation generally weaker than other mid-latitude western boundary currents ( such as the Gulf Stream, the Kuroshio current ).

In 1948 Henry Stommel proposed a circulation for the entire ocean depth by starting with the same equations as Sverdrup but adding bottom friction, and showed that the variation in Rossby ( eddy viscosity ), Sverdrup ( upper ocean wind driven flow ) and Stommel ( western boundary current flow ) and proposed a complete solution for the ocean circulation.

Because of conservation of potential vorticity caused by the northward-moving winds on the subtropical ridge's western periphery and the increased relative vorticity of northward moving water, transport is balanced by a narrow, accelerating poleward current, which flows along the western boundary of the ocean basin, outweighing the effects of friction with the western boundary current known as the Labrador current.

The low-salinity, better ventilated forms of WSDW and WSBW flowing along the outer rim of the Weddell Gyre have the position and depth range that would lead to overflow of the topographic confines of the Weddell Basin, whereas the more saline forms may be forced to recirculate within the Weddell Gyre are carried by the western boundary current of the Weddell Sea into the northwest corner of the Weddell Gyre.
