Isobaric map of the maximum value of the cloud mass density in the atmosphere and OLR for each simulation of WASP-43 b, centred on the dayside. On the left, clouds are composed of MnS, and of Mg₂SiO₄ on the right. Each row displays a simulation with a different cloud particle size, from 0.1 μm to 5 μm. In all our simulations, clouds preferentially form on the nightside and at the western terminator, leaving a cloudless dayside from which most of the thermal flux is emitted.
