There are two main driving forces for ocean currents; surface wind and the (horizontal) gradients in temperature and salinity. We usually assume that if you uniformly warm the ocean, there will be no major impact on ocean circulation. Accounting for the top-down nature of ocean warming changes that picture, she adds. The heat in the water is carried to higher latitudes by ocean currents where it is released into the atmosphere.

This study applied eigenvector-based time-decomposition and spatial-decomposition techniques to examine mechanisms through which the positive Indian Ocean Dipole (IOD) sea surface temperature (SST) pattern can influence the patterns of summer rainfall over southern Africa. Currents, like winds in the atmosphere, do not move in straight lines because of the spin of the Earth, which causes the Coriolis effect. Large masses of water that move together, called ocean currents, transport heat, marine organisms, nutrients, dissolved gasses such as carbon dioxide and oxygen, and pollutants all over the world.
