Title:On the topographic rectification of ocean fluctuations
Book title:-
Editorial:Kluwer academic publishers, Dordrecht
Abstract:Stochastic fluctuations acting on a model of quasigeostrophic fluid motion
on a rotating frame are shown to be rectified giving rise to
large-scale noise-sustained average currents. As in other noise
rectification phenomena, the effect requires nonlinearity and absence of
detailed balance to occur. We apply an analytical
coarse-graining procedure to obtain insight into the phenomenon.
Relevance of the effect in the context of ocean modeling is
briefly discussed.
