Modelled temperature profiles at different longitudes, averaged in latitude (thick lines). The light lines represent the temperature profiles at each latitude (spaced every 3.75°). (a) Cloudless simulation at solar metallicity. (b) With Mg₂SiO₄ clouds of 1 μm at solar metallicity. (c) Cloudless at 10× solar metallicity. (d) With Mg₂SiO₄ clouds of 1 μm at 10x solar metallicity. The solid grey line represents the condensation curves of Mg₂SiO₄ at solar metallicity, and the dashed grey line is the condensation curve of Mg₂SiO₄ at 10× solar metallicity.
