Eigenfunctions describing the oceanic tidal response for a supercontinent of angular radius θ_c = 10° (i.e. θ₀ = 170°), and associated tidal flows. Top: set {Φ_k} (SCHNs). Bottom: set {Ψ_k} (SCHDs). The orange disk designates the continent. The eigenfunctions are computed from the expression given by Eq. (C.19), and their real parts are plotted for l_n such that n = 0,…, 3 (vertical axis) and −n ≤ m ≤ n (horizontal axis). Bright or dark colours designate positive or negative values of the eigenfunctions, respectively. Streamlines indicate the tidal flows corresponding to for the set {Φ_k} and to for the set {Ψ_k}.
