Ekman spiral, theoretical displacement of current direction by the Coriolis effect, given a steady wind blowing over an ocean of infinite depth, extent, and uniform eddy viscosity. According to the concept proposed by the 20th-century Swedish oceanographer V.W. Ekman, the surface layers are displaced 45° to the right in the Northern Hemisphere (45° to the left in the Southern Hemisphere), and successively deeper layers are further displaced so that at a given depth the water motion is

The Ekman Spiral We consider now an elegant method of describing the wind in the boundary layer, due originally to V. Walfrid Ekman. The momentum equations will be taken in the form du dt −fv + 1 ρ0 ∂p ∂x + ∂ ∂z w0u0 = 0 dv dt +fu+ 1 ρ0 ∂p ∂y + ∂ ∂z w0v0 = 0 When the eddy ﬂuxes are parameterized in terms of the

The Ekman spiral is an equiangular spiral having the geostrophic wind as its limit point. Below the geostrophic wind level the wind blows across the isobars toward low pressure, at an angle that is a maximum at the surface and does not exceed 45°. The deviation of the wind vector from the geostrophic wind vector diminishes upward at an exponential rate. This net water movement is called Ekman transport (Figure 9.3.1). Figure 9.3.1 The Ekman spiral, shown for the Northern Hemisphere. Wind blowing over the water (blue arrow) creates a surface current 45 o offset from the wind. Each successive layer of water is moved and deflected by the layer above, creating a spiraling pattern of water movement that diminishes with depth.

Ekman Spiral is a musical collaboration project, writing and recording original songs. The songs are written by Carl Nelson. Carl does vocals, plays guitar(s), bass and occasionally drums. Most tracks have Brendan Coughlan’s drums and percussion as their foundation.

Ekman spirals are also found in the atmosphere. The Ekman spiral and Ekman transport are named for Swedish scientist V. Walfrid Ekman who first described the spiral in 1905. To help him make a mathematical model of these movements, Ekman used the observations that Fridtjof Nansen made while frozen into the Arctic sea ice.

One can also find the total mass transport of water involved in this Ekman-spiral current, by multiplying the velocity components \(u\) and \(v\) by the water density \(\rho\) and integrating Equations \ref{7.8} over the depth from \(0\) to \(\infty\).

The Ekman layer near the surface of the ocean extends only about 10 – 20 meters deep, and instrumentation sensitive enough to observe a velocity profile in such a shallow depth has only been available since around 1980.
