The integral is solved using FSU average annual cycle winds and an eastern boundary condition of the 1 cpy harmonic of observed Z20 along the coast. Integrating westward, dx is negative.
Coastal boundary condition:
- 1 cpy harmonic of Z20, showing the phase along the coast
- Another way of showing the coastal harmonic (These values were used to compute the coastal BC for the model).
- Z20(t) along coast
- Mean coastal BC from winds (Sverdrup) and obs (AOML XBT Z20)
Annual cycle from ERS and FSU (doesn't work -> not a equilibrium balance)
(Also see figures on the winds page dealing with coastal work).
- Observed and modeled amplitude and phase for various c (KW speed):
No damping: c=1.5 m/s c=2.0 m/s c=2.5 m/s c=3.0 m/s c=2.0 m/s (wind part only)
9-month damping (c=2.0 m/s): Model/obs Add difference amp/phase Blank phase for low amplitude
- Harmonics shown as vectors: (4 panels = Obs, Total, Wind part, BC part):
No damping: c=1.5 m/s c=2.0 m/s c=2.5 m/s c=3.0 m/s
9-month damping: c=2.0 m/s c=2.0 m/s (correlations) c=2.5 m/s
