Simulations showing the impact of the droplet setting velocities on the cloud opacity. (a) Vertical profiles of methane ice concentration and cloud column opacity on Uranus derived from CMM for K_eddy (p ≥ 0.4 bars) = 0.5 m² s⁻¹, with droplet settling velocities decreased by a factor of 10. For comparison, the baseline simulation (left panel of Fig. 1) is also shown. (b) Variation of the cloud total opacity over time when K_eddy is decreased by a factor of 100 in the simulations shown in (a). Time = 0 represents the moment when the sudden decrease in K_eddy is applied in the simulations.
