Globally averaged vertical profiles of vapor (red) and condensate (blue) VMRs, together with the saturation vapor VMR (green), for KCl, Na₂S, and MnS (left to right) in the T_eff = 600 K and P_rot = 20 h case at t_run = 1000 d averaged over the final 10 days. Solid curves show the fiducial model including convective mixing; dashed curves show an advection-only variant with convective diffusion omitted.
