totalEnstrophySpatiallyIntegrated

Potential enstrophy evaluated from the gridded QGPV field.

---

Declaration

 enstrophy = totalEnstrophySpatiallyIntegrated()

Returns

• enstrophy horizontally averaged potential enstrophy

Discussion

Potential enstrophy evaluated from the gridded QGPV field.

This scalar diagnostic evaluates one half of the QGPV variance integrated over depth, or multiplied by equivalent depth for the barotropic transform.
