Agulhas Current
The Agulhas Current is a warm current that flows down the east coast of Africa. It contributes to the warm climate of South Africa and is known for being one of the fastest flowing currents. It influences the global climate by affecting the transfer of heat between the Indian Ocean and the Atlantic Ocean, an important factor in global thermohaline circulation.
Gulf Stream
The Gulf Stream is a powerful, warm, and swift Atlantic ocean current that originates in the Gulf of Mexico, stretches to the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean. It influences the climate by making Northwestern Europe significantly warmer and milder than it would otherwise be at its latitude.
Humboldt Current
Also known as the Peru Current, this is a cold, low-salinity ocean current that flows north along the western coast of South America. It is one of the most productive marine ecosystems in the world due to upwelling of nutrient-rich water, influencing local weather by bringing cool temperatures and dense fog to coastal areas. It also has a global impact by contributing to a rich marine biodiversity.
California Current
The California Current is a Pacific Ocean current that moves southward along the western coast of North America, beginning off southern British Columbia and extending to Baja California. It brings cool and relatively low-salinity water from the north and has profound effects on the climate of California and the Pacific Northwest, contributing to the frequent fog in coastal areas and moderating the climate.
Kuroshio Current
This is a warm north-flowing ocean current on the west side of the North Pacific Ocean. It extends from Taiwan to the northeast of Japan. The Kuroshio stabilizes the temperature of the air above it, leading to milder winters than one would expect at such high latitudes in Japan and nearby regions.
North Atlantic Drift
An extension of the Gulf Stream, the North Atlantic Drift is a powerful warm Atlantic ocean current that continues northeast after the Gulf Stream nordens out. It plays a significant role in warming the climate of Western Europe, thus making the UK and Norway warmer than other regions at the same latitude.
