The Benguela current surges equator wards in the north-westerly direction to merge with South Equatorial current thus completing the anti-clockwise circulation of the South Atlantic Ocean. Etymology. They can flow for thousands of miles and are found in all the major oceans of the world. The South Equatorial Current (SEC) in the southern Indian Ocean bifurcates at the east coast of Madagascar into the Northeast and Southeast Madagascar Currents (NEMC and SEMC, respectively). The pathways for cross-equatorial and cross-gyre exchange are studied with an extensive set of new high-quality hydrographic data. These gyres are driven by the combination of trade winds in the tropics and westerly winds that are found south of about 30 degrees south, through a rather complicated process that includes western boundary current intensification. Journal of Geophysical Research, 99(22), 501-22, 512. a) Every ocean, except the Arctic Ocean, has a North Equatorial Current, a South Equatori-al Current and an Equatorial Counter Current. reaches its greates strength just below the equator, where it encounters the coast of Brazil and splits in 2. The East Australian Current (EAC) is the southward western boundary current that is formed from the South Equatorial Current (SEC) crossing the Coral Sea and reaching the eastern coast of Australia.At around 15° S near the Australian coast the SEC divides forming the southward flow of the EAC. for latitude and directly related to heat flux, salt transfer, and nutrient trap. Sense of "presently in effect" is from mid-15c. (2002). An ocean current is a continuous movement of ocean water from one place to another. Ocean currents are created by wind, water temperature, salt content, and the gravity of the moon.The current's direction and speed depend on the shoreline and the ocean floor. Falkland Current 7.

Monsoon Current 14. The theme of this book is the inter-hemispheric and inter-gyre exchanges of heat, salt and fresh water, while its goal is to improve the knowledge of the tropical Atlantic dynamics and how it affects the global ocean. Circulation at the western boundary of the South and Equatorial Atlantic: There is no interannual variability in the wind fields of this data set. The results presented here are from the fourth year of a 10-year seasonal cycle run. The Antarctic Circumpolar Current or the West wind Drift . Directly on the equator, the winds reverse twice a year due to the monsoons, and so the surface current can be either eastward or westward. The seasonal transport of the equatorial Undercurrent in the western Atlantic Molinari, R.L., 1983: Mayer, DA, RL Molinari, and FJ Festa, 1998: In El Nino years, this current intensifies in … Within the southern hemisphere, the South Equatorial Current is the westward limb of the very large-scale subtropical gyres. Surrounding ocean waters are warm, pushed by equatorial and counter-equatorial currents. A Model of the Seasonal Cycle in the Tropical Atlantic Ocean, In this paper, seasonal variation of the South Equatorial Current (SEC) bifurcation off the Madagascar coast in the upper south Indian Ocean (SIO) is investigated based on a new climatology derived from the World Ocean Database and 19-year satellite altimeter observations. In observational and reanalysis data, interannual variations of the NEMC and SEMC transports are strongly correlated with those of the SEC transport, rather than those of the SEC bifurcation latitude (SBL). In the Pacific, its core of maximum velocity lies at a depth of about 100 meters within the South Equatorial Current. Brazil Current Warm currents 1. Related: Currentness.

The name for these winds was coined by sea captains who sailed for trading companies and took advantage of their persistent speed and direction when crossing the ocean. Trade winds drive both North and South Equatorial Currents westward, thus transporting warm ocean-surface waters in that direction. The south equatorial current, partly led by the corresponding current of the Pacific Ocean, flows from east to west and thus, southward along the coast of Mozambique in Africa. The westward South Equatorial Current (SEC) stretches from 8° to 20°S, which is con-sistent with the observations in Schott et al. South Pacific Subtropical Gyre. The movement of the Indian South Equatorial Current is particularly strong off the Somali coast and southeastern Arabia, where upwelling lowers the surface temperature of the water near shore. Brazil's current account deficit widened to USD 1.58 billion in July of 2021 from USD 0.65 billion in the same month of the previous year and compared with market expectations of a USD 0.65 billion shortfall. 23½°N. © 2003-2012 Princeton University, Farlex Inc.
