Explanation:
There are two equatorial current flowing from east to west – the North EC and South EC. In between the two, there flows a equatorial counter current in the opposite direction, i.e from west to east. Now, it is said that piling up of waters in the area near Brazil, due to convergence of the two equatorial currents give rise to the equatorial counter current. This is because in this area due to convergence, the water is raised.
