Abstract: he classic baroclinic, wind-driven, double gyre problem is considered over a range of deformation radii, wind stress amplitudes, and bottom friction coefficients with the aim of better understanding the transfer of energy ...

Abstract: Recently a new class of coarse-grained equations, known as α models, have been proposed for the mean motion of an ideal incompressible fluid. The use of one such model to represent the time-mean component of a turbulent ...

Abstract: The dynamics of an idealized wind-driven double-gyre circulation in an ocean basin are studied from a dynamical systems point of view in an effort to better understand its variability. While previous analyses of this ...

Abstract: This paper presents analytical and numerical results for a class of turbulence closure models called ?alpha models,? in which Lagrangian averaging and turbulence closure assumptions modify the Eulerian nonlinearity. The ...
