enstrophy

I wish that I could make a career claiming that I do not have the dynamical PDE system accurately approximated, that I do not have the correct spectrum physical decay of enstrophy, and that I do not have the right forcing, but I have the right answer.

If the turbulence is not properly resolved, the model will blow up because of an accumulation of energy at the highest waves due to the unresolved cascade of enstrophy.

That will determine how rapidly the enstrophy can cascade down the spectrum for the Lu et al. example for convergent numerical approximations at least in the first day or so of the two different continuum systems and how much of a role the dissipation is playing in controlling that cascade.

I would surmise that these model forcings, e.g. solar, must be larger than the real forcings because the coupled climate models have a much faster removal of energy and enstrophy than the real atmosphere.

One of the problems with using the incorrect viscosity is that the cascade of enstrophy is incorrect.

That is, the small scales are just a sink of energy or enstrophy, and contribute nothing else in those cases.

If the enstrophy can cascade down from balanced large scale flow in a matter of hours because of large exponential growth near a jet, locally the scales are not separated , i.e. smaller scales can form very quickly even from a balanced large scale state.

What happens to features that develop in the smaller scales of motion as the enstrophy rapidly cascades down the spectrum?

The potential-enstrophy-, kinetic-energy, and mass-conserving ocean module calculates diffusion of energy below the ocean mixed layer and multiple layers below each surface ocean grid cell.

Energy from the potential-enstrophy-, kinetic-energy, and mass-conserving ocean module are used to drive melting of sea ice from below.
