Cloud concentration and total opacity (upper panel) in Uranus atmosphere derived from the microphysical model when K_eddy is decreased by a factor of 10 at pressures greater than 1 bar (lower panel). The decrease in K_eddy is applied to the steady-state simulations for K_eddy (p ≥ 0.4 bars) = 1 m² s⁻¹ (solid lines in the upper panel). The cloud profiles after 10 hours and 10 days of this decrease are represented by the dashed and dotted lines in the upper panel.
