The North Equatorial current flows in the equatorial zone of the Northern Hemisphere, from east to west. It is named as such because it flows near the equator in the northern part of the globe.
The South Equatorial current, on the other hand, flows in the equatorial zone of the Southern Hemisphere, also from east to west. It is named accordingly due to its location near the equator in the southern hemisphere.
The terms "North" and "South" in their names refer to the hemispheres in which they are located, while "Equatorial" indicates their proximity to the Earth's equator.
