North Brazil Current

Overview

The North Brazil Current (NBC) is a western boundary current that flows off the coast of northeast Brazil and retroflects between 4°N and 10°N.

The NBC sheds large anticyclonic rings that move northwestward along the continental break. (Didden and Schott, 1993). These warm rings could play an important role in the net meridional transport of warm water in the upper layers of the Atlantic Ocean as part of the meridional overturning circulation (MOC).
