WVTransformStratifiedQG

Create a stratified quasigeostrophic transform.

---

Declaration

 wvt = WVTransformStratifiedQG(Lxyz,Nxyz,options)

Parameters

• Lxyz length of the domain (in meters) in the three coordinate directions, e.g. [Lx Ly Lz]
• Nxyz number of grid points in the three coordinate directions, e.g. [Nx Ny Nz]
• options.N2Function function returning squared buoyancy frequency on [-Lz,0]
• options.rhoFunction function returning density on [-Lz,0]
• options.latitude latitude in the supported domain; default 33
• options.shouldAntialias exclude quadratically aliased modes; default true
• options.rho0 reference density in kilograms per cubic meter; default 1025

Returns

• wvt new WVTransformStratifiedQG instance

Discussion

Creates a new instance of the WVTransformStratifiedQG class for quasigeostrophic flow in variable stratification.

Supply either N2Function or rhoFunction. This transform represents the geostrophic A0 coefficients and has no wave Ap or Am content. Additional modal arrays accepted by the constructor are reconstruction state used by persistence.
