"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 ...

Ekman transport at equator

WebThe upwelling of colder ocean water at the equator is an example of a situation where the Coriolis force, although small, is important. Imagine a steady easterly wind along the equator ( Fig 1 ). Since the Ekman … 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.

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.

WebThe easterly trade winds cause northward Ekman transport just to the north of the equator and southward Ekman transport just to the south of the equator. This causes upwelling at the equator. As a result, the pycnocline shoals towards the equator. This drives a westward geostrophic flow at the sea surface, much like the eastern boundary current ... 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 …

WebIn the open ocean, trade winds also caused Ekman transport. Along the equator prevailing winds blow from east to west. This causes water to move away from the equator in both the northern and southern hemispheres. … WebView ERTH 110 lab 7 Spring 2024 Ekman transport.docx from KINE 247 at California State University, Chico.
