Record #185777:

Energetics of the global ocean: the role of layer-thickness form drag / Hidenori Aiki, Kelvin J. Richards.

Title: Energetics of the global ocean: the role of layer-thickness form drag / Hidenori Aiki, Kelvin J. Richards.
Author(s): Aiki, Hidenori.
Richards, Kelvin J.
Date: 2008.
In: Journal of Physical Oceanography. (2008.), Vol. 38(9) (2008)
Abstract: Presents results of analysis of high-resolution numerical simulation with particular reference to energetics in density space, and demonstrates role of layer-thickness form drag (residual effects of hydrostatic pressure perturbations) hidden in classical analysis of energetics of flows. Though study provides direct evidence to verify some basic characteristics of layer-thickness form drag, result of analysis disagrees with speculation that layer-thickness form drag in Antarctic circumpolar current (ACC) is agent that transfers wind-induced momentum near sea surface downward to bottom layers. Energy analysis conducted in this study suggests that layer-thickness form drag reduces and thereby cancels vertical shear resulting from eddy induced overturning circulation, rather than vertical shear resulting from surface wind stress.
