Cold ocean currents are ocean currents with waters of low temperature, i.e. the waters are cold. In Africa the main cold ocean currents include; the cold Benguella current and the cold canary current. Elsewhere examples include the Californian current, cold Peruvian current, the North equatorial current, East Greenland current and the West Australian current.
The following are Characteristics of cold ocean currents
- They are characterized by low temperatures, i.e. they have low waters.
- They tend to flow from high latitude regions to regions of low latitude, i.e. they flow equator wards from regions of cold conditions.
- They generally flow on the western side of the continental landmasses. This is true in the lower latitude regions.
- In the mid and high latitude regions, they tend to flow on the eastern sides of the continents e.g. the Labrador Current, the Oya siwo current.
- They tend to characterized by high density/low salinity.
- In the northern hemisphere their circulation tends to be anti-clockwise while in the southern hemisphere their circulation tends to be clockwise.
- They are also characterized by up-welling of waters at the coasts.
