Plots of ρ₁∕ρ₀ (top panel), J_*,1∕J_*,0 (middle panel), and γ₁∕γ₀ (bottom panel) after one period of an internal gravity wave, as a function of the amplitude of the density perturbation used to drive the waves. The nucleation plot shows a strong non-linear increase in response to increased perturbation amplitude, more pronounced with low driving frequencies. The impact on dust growth is much weaker, and growth increases with the driving frequency. The measurements are taken as the maximum values along a vertical slice of the numerical domain, located at a distance X(ω) from the centre of the domain so that X(ω) = X_refω_ref∕ω.
