(A)symmetry of the Lamb resonance. Similar to Fig. 2, the imaginary part of the normalized pressure anomaly (Eq. (22)), which is associated with the semidiurnal tide, is plotted as a function of the normalized forcing frequency ω = (Ω − n_⋆)/n_⋆ = σ/2n_⋆, for the same planetary-stellar parameters. We focus here on the high frequency regime around the Lamb resonance. Different panels correspond to different values of σ_bl, or different thermal inertias in the ground and the atmosphere. Allowing for thermal inertia results in a delayed ground response, of which the signature is clear in inducing an asymmetry in the spectral behavior around the resonance.
