10.21.10: Wave amplitude and mean flowsΒΆ

I present here measures of the wave amplitude versus the Laplacian dissipation coefficient and the mean flow quantities (Lagrangian-mean zonal velocity, Eulerian-mean zonal velocity and zonal Stokes drift). The wave amplitude is defined as the maximum of the meridional velocity during a cycle (during days 2000-2100) at the center of the domain. The measures of the mean flow amplitude are from the same location.


Figure 1: (a) Squared wave amplitude versus the Laplacian dissipation coefficient. (b) Square wave amplitude versus zonal mean flow quantities. The dashed red line (b) is the Stokes drift computed using the third-order theoretical formula. The black dashed line in (b) is the one-to-one relationship.


Figure 2: As in Fig.1 but the suite of experiments with twice the amplitude of the forcing.
