Resonance in optimal perturbation evolution. Part II: Effects of a nonzero mean PV gradient

Optimal perturbations are constructed for a two-layer -plane extension of the Eady model. The surface and interior dynamics is interpreted using the concept of potential vorticity building blocks (PVBs), which are zonally wavelike, vertically confined sheets of quasigeostrophic potential vorticity....
