Ekman transport at equator

http://oceanmotion.org/html/background/ocean-in-motion.htm Web•Ekman transport is caused by the Coriolis effect on the surface ocean circulation, resulting in a net transport of surface water perpendicular to the wind direction. •Thermohaline circulation is a global-scale ocean circulation driven by differences in temperature and salinity, with cold, dense water sinking in the polar regions and warm ...

(IPMOC gradually decays north of the equator, as seen in Figure S1 in Supporting Information S1), and for comparison with the subtropical … Ekman transport is part of Ekman motion theory, first investigated in 1902 by Vagn Walfrid Ekman. ... There is a great deal of upwelling Ekman suction at the equator because water is being pulled northward north of the equator and southward south of the equator. This leads to a divergence in the water, resulting … See more Ekman transport is part of Ekman motion theory, first investigated in 1902 by Vagn Walfrid Ekman. Winds are the main source of energy for ocean circulation, and Ekman transport is a component of wind-driven ocean … See more Ekman theory explains the theoretical state of circulation if water currents were driven only by the transfer of momentum from the wind. In … See more Ekman suction is the component of Ekman transport that results in areas of upwelling due to the divergence of water. Returning to the concept of … See more Some assumptions of the fluid dynamics involved in the process must be made in order to simplify the process to a point where it is solvable. The assumptions made by Ekman were: • no boundaries; • infinitely deep water; See more There are three major wind patterns that lead to Ekman suction or pumping. The first are wind patterns that are parallel to the coastline. Due … See more Ekman Pumping is the component of Ekman transport that results in areas of downwelling due to the convergence of water. As discussed above, the concept of mass conservation requires that a pile up of surface water must be pushed downward.

http://sam.ucsd.edu/ltalley/sio210/Equatorial_circulation/index.html WebApr 6, 2024 · The net water transport is from the equator, where surface outflow is replaced by upwelling, towards the centers of the Pacific subtropical gyres of both hemispheres. Geostrophic convergence is a response to the Ekman divergence to balance variations in sea surface height from the subtropical gyres to the equator.

WebΤhe east-to-west wind across the tropical ocean waters induces Ekman transport divergence at the Equator, which cools the surface water there. At the geographic Equator a jetlike current is found just below the sea surface, flowing toward the east counter to the surface current. This is called the Equatorial Undercurrent. It attains speeds of ... WebEven though the wind-driven Ekman transport is confined to a thin surface layer in the ocean, it plays a critical role in the global heat balance. Ekman transport is responsible …

As shown in Figure 1.10, the global surface wind patterns are such that the winds are from the northeast north of the equator and from the southeast south of the equator (dark arrows). The net movement of water in the wind-driven layer as a result of the Ekman Transport will be away from ...

WebEkman transport also turns currents caused by higher latitude westerly winds towards the equator. This creates regions of convergence in the transition zone between the easterlies and the westerlies. Combination of wind direction and Ekman transport causes water to converge at mid-latitudes in the middle of the major ocean basins.
