Friction in mid-latitude cyclones: an Ekman-PV mechanism
Ekman transport is the net motion of fluid as the result of a balance between Coriolis and turbulent drag forces. In the picture above, the wind blowing North in the northern hemisphere creates a surface stress and a resulting Ekman spiral is found below it in the water column. Ekman transport is part of Ekman … 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 the physical world, this is difficult to observe because of the influences of many simultaneous current driving forces (for … 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 … See more • Ekman transport leads to coastal upwelling, which provides the nutrient supply for some of the largest fishing markets on the planet and can impact the stability of the Antarctic Ice Sheet by pulling warm deep water onto the continental shelf. Wind in these … 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 to the Coriolis effect, surface water … 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: See more cinemas west ocala

WebDec 1, 2000 · It is well known that “Ekman pumping”, a horizontal divergence in Ekman boundary layer, is an essential factor of the geostrophic motion dissipation. ... Therefore, it seems to be useful to know the solution of spin-down problem within the framework of this model. But, as we know, the efforts to find the corresponding explicit analytical ... WebMay 23, 2002 · Spin-up in a rectangular container with a free surface is investigated numerically and experimentally. In the formulation of two-dimensional numerical computation, we use a potential-like function in addition to the stream function to deal with the first-order Ekman pumping model.
