Ocean Circulation Kinetic Energy: Reservoirs, Sources, and Sinks (2009, background): “Arbic and Flierl (2004) found that moderate bottom friction is required for the modeled geostrophic turbulence to reproduce the observed amplitudes, vertical structure, and horizontal scales of mid-latitude eddies.”
Global observations of large oceanic eddies (2007, background): “Recent modeling supports this view and suggests that dissipation may play an important role in determining the large eddy diameters [Arbic and Flierl, 2004].”
Using a resolution function to regulate parameterizations of oceanic mesoscale eddy effects (2013, background): “Arbic and Flierl (2004) demonstrate that a strong quadratic bottom drag serves the purpose of giving idealized eddies this structure, while noting that in the real ocean form drag exerted by rough bathymetry could fill an analogous role.”
Global energy conversion rate from geostrophic flows into internal lee waves in the deep ocean (2011, background): “It is believed that the eddy field in turn loses its energy through friction in bottom boundary layers [Arbic and Flierl, 2004] and along western boundaries [Zhai et al.”
