Sunlight warms the waters on the ocean surface. Some heat energy is transferred to cooler waters through convection.
As water is on top of the ocean, wind pushes it along, creating a current. As it warms, it interacts with lower colder waters, pulling them along with it. As water cools, it rises and this interaction creates ocean currents.

Equator due to the trade winds pushing the surface waters westward. This creates the Equatorial Counter Current, which flows eastward at the surface.
Ocean currents.
waters of the ocean that move in giant streams are called currents.
Ocean currents moving away from the equator typically bring colder waters from higher latitudes towards the equator. These colder waters often carry nutrients, which can impact marine ecosystems and provide a source of food for various marine organisms.
Cyclones cannot hit Adelaide. Cyclones form in warm tropical waters, and then follow warm currents, but no warm currents extend from Australia's warmer waters to the south where Adelaide is located.

Tropical ocean waters are more saline than colder waters because tropical waters undergo ocean currents due to the vertical and horizontal movement of seawater.
