Ocean current the windthe Coriolis effect plays a role in their behaviours. The thermohaline circulation is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. The adjective "thermohaline" derives from "thermo-" referring to temperature and "" referring to salt content, factors which together determine the density of sea water. Wind-driven surface currents (such as the Gulf Stream) travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows into the ocean basins. While the bulk
West Australian Current on the Western Australian Coast, the Leeuwin Current and Southern Australian Countercurrent, also flow along this coast, with the former flowing in the opposite direction. These 3 currents together contribute greatly to the rainfall and climate in the southwest region of Western Australia. West Australian Current The West Australian Current (or the Western Australian Current), is a cool surface current of the Southern Ocean and Southern Indian Ocean. It starts as the Southern Indian Ocean Current, a part of the larger Antarctic Circumpolar Current (also known as the West Wind Drift). As the current approaches Western Australia, it turns north,
