Declaration

 setGeostrophicForcingCoefficients(A0bar,options)

Parameters

• A0bar A0 values on the transform spectral grid
• MA0 optional logical A0 selection mask; default abs(A0bar) > 1e-6*max(abs(A0bar(:)))

Discussion

Without an explicit mask, coefficients whose magnitude is at least \(10^{-6}\) times the largest supplied magnitude are selected. If adaptive damping is registered, selected modes above its horizontal k_damp threshold are removed.
