An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, ...
The Kuroshio current is warm, compared to cooler waters in the Yellow Sea, and Sea of Japan. The Kuroshio is a relatively warm ocean current with an annual average sea-surface temperature of about 24 °C (75 °F), is approximately 100 kilometres (62 mi) wide, and produces frequent small to meso-scale eddies.
Marine currents can carry large amounts of water, largely driven by the tides, which are a consequence of the gravitational effects of the planetary motion of the Earth, the Moon and the Sun. Augmented flow velocities can be found where the underwater topography in straits between islands and the mainland or in shallows around headlands plays a major role in enhancing the flow velocities ...
Overview of climatic changes and their effects on the ocean. Regional effects are displayed in italics. [1] This NASA animation conveys Earth's oceanic processes as a driving force among Earth's interrelated systems. There are many effects of climate change on oceans. One of the most important is an increase in ocean temperatures.
The Humboldt Current, also called the Peru Current, is a cold, low-salinity ocean current that flows north along the western coast of South America. [1] It is an eastern boundary current flowing in the direction of the equator , and extends 500–1,000 km (310–620 mi) offshore.
This current as part of a baroclinically unstable system meanders and creates eddies (in much the same way as a meandering river forms an oxbow lake). These types of mesoscale eddies have been observed in many major ocean currents, including the Gulf Stream , the Agulhas Current , the Kuroshio Current , and the Antarctic Circumpolar Current ...
Surface currents flow at a 45° angle to the wind due to a balance between the Coriolis force and the drags generated by the wind and the water. [7] If the ocean is divided vertically into thin layers, the magnitude of the velocity (the speed) decreases from a maximum at the surface until it dissipates.
The Somali Current is a cold ocean boundary current that runs along the coast of Somalia and Oman in the Western Indian Ocean and is analogous to the Gulf Stream in the Atlantic Ocean. [1] This current is heavily influenced by the monsoons and is the only major upwelling system that occurs on a western boundary of an ocean.
