Plain Language Summary: We analyse the set of 40-day-long kilometre-resolution global atmospheric simulations of the DYAMOND model intercomparison project over the South-East Atlantic to study how this new family of models simulate subtropical marine low clouds. Such clouds represent a critical uncertainty in climate-change projections. The simulations produce low cloud fields that look in general realistic in comparison to satellite images, but there are considerable inter-model differences. Detailed analyses show that the relevant dynamical and physical processes of the marine boundary layer are consistently represented by the analysed models, indicating that there is a potential to improve the simulated low cloud cover through model calibration.
