Abstract: Whereas Rayleigh-Bénard convection is a classical problem in fluid dynamics and complex systems, atmospheric moist convection harbors a number of additional phenomena, such as large-scale segregation into cloudy and cloud-free subregions (known as convective self-aggregation) or the emergence of mesoscale convective systems - self-organized clusters of convective cells. Treating the population of convective cells as a form of interacting particle system, we discuss several simple toy models, which highlight some mechanisms involved in tropical cloud organization. We make contact to results obtained from idealized fluid dynamics simulations of the tropical atmosphere and highlight, where discrepancies between simulations and observations exist and could be bridged.
