8). The total relief of the ocean surface (not counting waves or tides) is only about 1.5 meters, but this is sufficient to drive the ocean circulation. To understand how the wind stress distorts sea level, with hills at the convergences, valleys at the divergences, one needs to invoke the hydrostatic relationship.
