What is the difference between a poleward moving current and a equatorward moving ocean current?

Answer 1

The interaction between the oceans surface and the circulation of the lower atmosphere is the primary cause of the surface currents in the oceans. A current generally refers to the horizontal movement of water. The direction, speed, and the temperature of the water masses moved by the ocean currents play an important role in climatology by transporting heat energy. Currents may be small-scale, transient features, resulting from seasonal or local effects or large-scale, permanent features, covering vast portions of the oceans, resulting from atmospheric circulation patterns
