Plain Language Summary: The impacts of number of cloud condensation nuclei (CCN) on moist Rayleigh convection were examined by using a simple 2D fluid model with a double moment microphysics model. The effect is most prominent in the initially formed convection, whereas the convection in the quasi-steady state does not significantly depend on the number of CCN. It is suggested that the former convection forms by local buoyancy, while the latter is largely influenced by boundaries.
