transformQGPVToWaveVortex

Project quasigeostrophic potential vorticity onto A0 coefficients.

---

Declaration

 A0 = transformQGPVToWaveVortex(qgpv)

Parameters

• qgpv QGPV field with the transform’s spatial shape

Returns

• A0 zero-frequency coefficients with the transform’s spectral shape

Discussion

Project quasigeostrophic potential vorticity onto A0 coefficients.

The input is a gridded QGPV field. The output uses the transform’s compact spectral layout and may be assigned to A0.

A0 = wvt.transformQGPVToWaveVortex(qgpv);
