The return flow occurs in an intense, narrow, poleward western boundary current.

Like the Gulf stream, it is a strong western boundary current.

These western boundary currents (of which the gulf stream is an example) are a consequence of basic fluid dynamics.

Western boundary currents (the Gulf Stream and Kuroshio) exist in order to return water to higher latitude.

The classical definition of the Mozambique Current is that it is a strong, steady, western boundary current.

It is an eastern boundary current flowing in the direction of the equator, and can extend 1,000 kilometers offshore.

Spatially, the focus is on the California Current region and coastal upwelling in eastern boundary currents.

These four eastern boundary currents comprise the majority of coastal upwelling zones in the oceans.

The Brazil Current is the western boundary current of the gyre.

An abundance of these fish species is a common feature of eastern boundary currents.
