KCl cloud structures using the log g = 3.25 (top row) and log g = 4.25 (bottom row) Y-dwarf temperature-pressure profiles from Gao et al. (2018) and assuming a constant K_zz = 10⁸ cm² s⁻¹. The dashed lines show the monodisperse size distribution, the dotted lines the exponential distribution, and the solid lines the exponential size distribution results. The left panels show the temperature-pressure profiles with the mass mixing ratio of the condensate, q₁, vapour, q_v and saturation point, q_s (pink dash-dot line). The middle panels show the representative particle sizes, r_c and r_p, and total number density, N_c. The right panels show the relative difference in r_c and N_c between the monodisperse and gamma cloud structure.
