Nyquist plot of the transfer function associated with the component of the semidiurnal tide, that is such that . The imaginary part of the normalized function is plotted in absolute value as a function of the real part in the reference case of the study (a = a_Venus and p_s = 10 bar). Values obtained using GCM simulations are indicated by points. They are interpolated by a green line in the range 0 ≤ ω < 3 (step Δω = 0.3), a black line in the range 3 ≤ ω < 30 (step Δω = 3), and a blue line in the range 30 ≤ ω ≤ 300 (step Δω = 30), being the normalized tidal frequency. Similarly, values obtained in these ranges with the model given by Eq. (32) for the surface thermal time τ_s = 0.3 days are designated by crosses. The red line corresponds to the function itself.
