WVNonlinearFluxQGForced

3D forced quasigeostrophic potential vorticity flux

---

Declaration

WVNonlinearFluxQGForced < WVNonlinearFluxQG

Overview

The 3D quasigeostrophic potential vorticity flux will only use and modify the A0 coefficients.

\[\frac{\partial}{\partial t} A_0^{klj} = \underbrace{M_{A_0}^{klj} \left(\bar{A}_0^{klj} - A_0^{klj} \right)/ \tau_0}_{F_\textrm{force}} + F_0^{klj} + F_\textrm{damp}^{klj}\]

To initialize the WVNonlinearFluxQGForced,

  model = WVModel(wvt,nonlinearFlux=WVNonlinearFluxQGForced(wvt,shouldUseBeta=1,uv_damp=wvt.uvMax));

Topics

• Equality
  • isequal check for equality with another nonlinear flux operation
• Initialization
  • nonlinearFluxFromFile initialize a nonlinear flux operation from NetCDF file
  • nonlinearFluxWithResolutionOfTransform create a new nonlinear flux operation with double the resolution
• Computation
  • setGeostrophicForcingCoefficients set forcing values for the geostrophic part of the flow
• Write to file
  • writeToFile write information about the nonlinear flux operation to file
• Other
  • A0bar A0 ‘mean’ value to relax to
  • MA0 Forcing mask, A0. 1s at the forced modes, 0s at the unforced modes
  • WVNonlinearFluxQGForced initialize 3D quasigeostrophic potential vorticity flux
  • addVariableOfType
  • compute this is ever so slightly faster (for barotropic only), but why add the complication?
  • forcingFlux
  • setNarrowBandForcing
  • tau0 relaxation time
