Cyclonic eddies rotate anticlockwise (clockwise) in the Northern (Southern) hemisphere and have a cold core. Anticyclonic eddies rotate clockwise (anticlockwise) in the Northern (Southern) hemisphere and have a warm core. The temperature and salinity difference between the eddy core and the surrounding waters is the key element driving vertical ...
The Great Whirl is a huge anti-cyclonic eddy generated by the Somali current flowing in (northern) summer, and one of the two gigantic Indian Ocean Gyres (the other is the Socotra Gyre). The Great Whirl can be observed between 5-10°N and 52-57°E off the Somali coast in the summer season, a location typically around 200 km southwest of the ...
The eddies appeared to be caused mostly by topography (particularly islands), wind, and instabilities in the current. These eddies lay mainly between the California Current (flowing toward the equator) and the coastline. [3] The majority of these eddies were cyclonic and had the ability to induce the upwelling of nutrient-rich water.
The world's largest ocean gyres. Western boundary currents may themselves be divided into sub-tropical or low-latitude western boundary currents. Sub-tropical western boundary currents are warm, deep, narrow, and fast-flowing currents that form on the west side of ocean basins due to western intensification. They carry warm water from the ...
Its contributing currents are the Loop Current and the Antilles Current. The current was discovered by Spanish explorer Juan Ponce de León in 1513. The Florida Current results from the movement of water pushed from the Atlantic into the Caribbean Sea by the rotation of the Earth (which exerts a greater force at the equator ).
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, amongst others. Mesoscale ocean eddies are characterized by currents that flow in a roughly circular motion around the center of the eddy.
Eddies normally travel around one mile per day in these areas; the smoke rings covered five to 10 miles per day and lasted for about six months before splitting up.
The Loop Current is an extension of the western boundary current of the North Atlantic subtropical gyre. [1] Serving as the dominant circulation feature in the Eastern Gulf of Mexico, the Loop Currents transports between 23 and 27 sverdrups [2] and reaches maximum flow speeds of from 1.5 to 1.8 meters/second.
