  • equator
  • The South Equatorial Currents of the Atlantic and Pacific straddle the equator. (wikipedia.org)
  • Researchers onboard set four buoy stations containing current chart recorders at 30°W. One of them, that was set at the intersection of this meridian with the equator under the thin layer of the South Equatorial Current had recorded the strong current eastwards. (wikipedia.org)
  • The salinity will then decrease to around 36.5 psu as the current moves northward toward the equator and into the presence of the Intertropical Convergence Zone (ITCZ). (wikipedia.org)
  • water
  • A rip current, often simply called a rip, or by the misnomer rip tide, is a specific kind of water current which can occur near beaches with breaking waves. (wikipedia.org)
  • citation needed] A rip is a strong, localized, and narrow current of water which moves directly away from the shore, cutting through the lines of breaking waves like a river running out to sea, and is strongest near the surface of the water. (wikipedia.org)
  • Rip currents can be hazardous to people in the water. (wikipedia.org)
  • A rip current forms because wind and breaking waves push surface water towards the land, and this causes a slight rise in the water level along the shore, which will tend to flow back to the open water by the route of least resistance. (wikipedia.org)
  • When there is a local area which is slightly deeper or a break in an offshore bar or reef, this can allow water to flow offshore more easily, and this will initiate a rip current through that gap. (wikipedia.org)
  • When the water in the rip current reaches outside of the lines of breaking waves, the flow disperses sideways, loses power, and dissipates in what is known as the "head" of the rip. (wikipedia.org)
  • Although rip tide is a misnomer, in areas of significant tidal range, rip currents may only occur at certain stages of the tide, when the water is shallow enough to cause the waves to break over the bar, and deep enough for the broken wave to flow over the bar. (wikipedia.org)
  • A fairly common misconception is that rip currents can pull a swimmer down, under the surface of the water. (wikipedia.org)
  • The term eddy current comes from analogous currents seen in water in fluid dynamics, causing localised areas of turbulence known as eddies giving rise to persistent vortices. (wikipedia.org)
  • It is predominantly a salt water current, but it does help transport fresh water from the Amazon River northward. (wikipedia.org)
  • Both are quite warm, so the densities are similar, and the currents mix and create water with a salinity of 37.1 psu . (wikipedia.org)
  • Closer to the shore, and especially where the depth of the water is less than 400 m, the sea floor acts as the lower limit to the current. (wikipedia.org)
  • magnitude
  • The magnitude of the current in a given loop is proportional to the strength of the magnetic field, the area of the loop, and the rate of change of flux, and inversely proportional to the resistivity of the material. (wikipedia.org)
  • physical
  • This allows measurement of the current in a conductor without the need to make physical contact with it, or to disconnect it for insertion through the probe. (wikipedia.org)
  • warm
  • For example, warm currents traveling along more temperate coasts increase the temperature of the area by warming the sea breezes that blow over them. (wikipedia.org)
  • branch
  • Deep ocean basins generally have a non-symmetric surface current, in that the eastern equatorward-flowing branch is broad and diffuse whereas the western poleward flowing branch is very narrow. (wikipedia.org)
  • Around 5°S, it merges with a northern branch of the South Equatorial Current (SEC) and increases its volume to 37 Sv, with its peak between 100m and 200m deep. (wikipedia.org)
  • known
  • An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp. (wikipedia.org)
  • For the case where space is a one-dimensional circle, current algebras arise naturally as a central extension of the loop algebra, known as Kac-Moody algebras or, more specifically, affine Lie algebras. (wikipedia.org)
  • Tim Eliot, better known by his stage name Current Value, is a German drum & bass producer and DJ. (wikipedia.org)
  • Where significant vertical movement of ocean currents is observed, this is known as upwelling and downwelling. (wikipedia.org)
  • winds
  • In these wind driven currents, the Ekman spiral effect results in the currents flowing at an angle to the driving winds. (wikipedia.org)
  • Since the current can be quite large, it is easy for large anticyclonic rings to generate, which separate from the main mass of the current and move northwestward with the prevailing winds. (wikipedia.org)
  • contributors
  • Contributors to Current History in the publication's early years included George Bernard Shaw, Winston Churchill, Charles A. Beard, Allan Nevins, and Henry Steele Commager. (wikipedia.org)
  • Shortly after Current History began publishing in 1914, its editor, Ochs Oakes, decided that a magazine recording "history in the making" should maintain as regular contributors a group of historians and social scientists. (wikipedia.org)
  • publication
  • After the bankrupted NAEB closed in 1981, Current resumed publication in 1982 as an independent journalistic service of the public television station WNET. (wikipedia.org)
  • Current Books claimed to be "the most widely distributed book publication in bookstores" at the time with copies for sale in 3,840 stores. (wikipedia.org)
  • Current History is the oldest United States-based publication devoted exclusively to contemporary world affairs. (wikipedia.org)
  • Current History addressed this episode in its October 1942 issue, maintaining that Smyth during the months that he held an ownership interest in the publication did not control editorial policies. (wikipedia.org)

  • Current OU students may be eligible for the following types of scholarships beyond their freshman year. (ou.edu)
  • strong
  • Ripple marks in sediments, scour lines, and the erosion of rocky outcrops on deep-ocean floors are evidence that relatively strong, localized bottom currents exist. (wikipedia.org)
  • narrow
  • Rip currents are usually quite narrow, but tend to be more common, wider and faster, when and where breaking waves are large and powerful. (wikipedia.org)

  • proportional
  • The Rogowski coil gives a voltage proportional to the rate of change of current in the primary cable, so more signal processing is needed before the sensed values can be displayed. (wikipedia.org)
  • electrical

  • Audio and radio signals carried on electrical wires are also examples of alternating current. (wikipedia.org)
  • Electrical energy is distributed as alternating current because AC voltage may be increased or decreased with a transformer . (wikipedia.org)
  • movement
  • Play media Play media Play media An ocean current is a seasonal directed movement of seawater generated by forces acting upon this mean flow, such as breaking waves, wind, the Coriolis effect, cabbeling, temperature and salinity differences, while tides are caused by the gravitational pull of the Sun and Moon. (wikipedia.org)
  • resistance

  • effect

  • Another example is Lima, Peru where the climate is cooler (sub-tropical) than the tropical latitudes in which the area is located, due to the effect of the Humboldt Current. (wikipedia.org)

  • direction
  • In 1834, Heinrich Lenz stated Lenz's law, which says that the direction of induced current flow in an object will be such that its magnetic field will oppose the change of magnetic flux that caused the current flow. (wikipedia.org)
