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
Western Cape along the southern slopes of the Outeniqua mountain range. Typical species are hardwoods of exceptional height, such as Yellowwood, Stinkwood and Ironwood trees. The Western Cape is also climatologically diverse, with many distinct micro- and macroclimates created by the varied topography and the influence of the surrounding ocean currents. These are the warm Agulhas Current which flows southwards along South Africa's east coast, and the cold Benguela Current which is an upwelling current from the depths of the South Atlantic Ocean along South Africa's west coast. Thus climatic statistics can vary greatly over short distances. Most of the province is
