Despite advances in knowledge development and modeling of cumulus convection, there are large unknowns and uncertainties in our understanding of the life cycle of convection. This session focuses on scientific advancements in measurements, methods, and modeling related to cumulus convection, such as but not limited to, deducing entrainment, convective microphysical processes, coupling boundary layer processes with cloud dynamics, aerosol influences on convective microphysics, cloud base mass fluxes, convective momentum transfer, convective detrainment and environment interactions, scale-aware convective formulations, development of unified cloud models (combined grid scale and subgrid scale cloud formulations), ideas for the development of two community convection parameterization schemes (mass flux and statistical/stochastic) to save resources and focus development efforts only on these community parameterizations, and other sub-topics relevant to the advancement of cumulus convection science as well as pollutant wet deposition modeling in air quality models.
