this cloud particle population in particular in transient regimes like at the day-night terminators. and [@Drummond2018a] demonstrate from HD189733b and HD209458b simulations that longitudinal quenching of C/H/O/N species occurs inside the jet regions and on the nightside. [@Mol2019] point out for HAT-P-7b, however, that the atmospheric optical depth is little effected, in particular if cloud particles form through other paths than C/H/O/N chemistry.

[*3D GCM input:*]{}We use the SPARC/MITgcm [@Showman2009] to determined the 3D thermal structure of WASP-43b. The model solves the primitive equations coupled to non-grey radiative transfer. We assume solar composition abundances including rainout of condensates but do not consider any cloud radiative feedback. Local chemical equilibrium is assumed, [ since]{}, as shown by @Steinrueck2019, the effect of disequilibrium chemistry on the thermal structure is small compared to the horizontal temperature contrasts. More details of the specific model run can be found in [@Parmentier2018; @2019arXiv190903233I]. For more details on the GCM approach, we refer the reader to the description in [@2019arXiv190608127H]. The outputs of our WASP-43b models are very similar to the ones of [@2015ApJ...801...86K] since both are utilising the same base 3D GCM code.

We run the simulation for 300 Earth days and average all physical quantities
