1
An Introduction to Dynamic Meteorology
This revised text presents a cogent explanation of the fundamentals of meteorology, and explains storm dynamics for weather-oriented meteorologists.
James R. Holton, Gregory J. Hakim, 2013

Atmospheric and Oceanic Fluid Dynamics: Fundamentals and ...
Rather, if the vertical scale in the Ekman layer is 5 (meaning z ~ 5) we must have
5 ~ Ek112. In dimensional terms this means the thickness of the Ekman layer is 5
= H5 = HEk112 (2.283) (2.284) [This estimate also emerges directly from ...

Encyclopedia of Geomagnetism and Paleomagnetism
apply and a new force balance is struck, and a new type boundary layer arises
called the equatorial Ekman layer. This is intimately linked to a free shear layer,
which surrounds the tangent cylinder, i.e., the imaginary cylinder touching the
inner ...
David Gubbins, Emilio Herrero-Bervera, 2007

Ocean Circulation and Climate: Observing and Modelling the ...
Ekman (1905) also pointed out that the scaling of the momentum balance
equations, with the above formula for magnitude of the Ekman velocity, implied
that the depth scale of the Ekman layer was proportional to wind friction velocity
and ...
Gerold Siedler, John Church, John Gould, 2001

The Atmospheric Boundary
Layer Over Polar Marine Surfaces
12/ . (131) Figure 21 shows plots of eq 130 in both the Northern and Southern
Hemispheres. The obvious feature in these hodographs is the so-called Ekman
spiral. The height of the Ekman layer, hE, is commonly taken as hE = π δ (132)
since ...

Introductory Dynamical Oceanography
Here, wE is the vertical velocity at the bottom of the Ekman layer associated with
convergence or divergence of the Ekman transport. If wE # 0, it requires a
corresponding divergence or convergence of the flow below. Denoting this flow
by (g ...
Stephen Pond, George L. Pickard, 1983

Modeling Dynamic Climate Systems
4.8 The Ekman Layer in the Atmosphere The atmosphere near the ground is
closely analogous to the upper ocean. The ground exerts drag on the lowest
layer of the air, which then, by the turbulent exchange of momentum, exerts a
drag on ...

Numerical Simulations of the Stratified Oceanic Bottom ...
The surface wind-driven Ekman layer forms when frictional terms contribute to the
leading order momentum balance, leading to an ageostrophic flow. Since the
velocity gradients, and hence the size of the viscous stresses are strongest at the
...
... changing the stratification modifies the structure of a BBL rather than to make
quantitative comparisons. Studies of the stably stratified atmospheric boundary
layer indicate that a stably stratified turbulent Ekman layer changes as follows by

Atmosphere-Ocean Interaction
6.1.1 The stationary laminar Ekman layer Ekman (1905) analyzed the problem as
one of viscous laminar flow. This is an idealization that is hardly, if ever, realized
in the PBLs. The results remain applicable, however, to some laboratory ...
