Description Process-level understanding of moist convection is relevant to many aspects of weather forecasting and climate simulation. Moist convection in the atmosphere is inherently a multi-scale phenomenon, from processes on the scale of cloud and precipitation particles, to cloud turbulence and entrainment, to cloud-scale updrafts and downdrafts, to mesoscale organization and the interaction of cloud fields with the large-scale environment. A key aspect is how these processes interact over this huge range of scales. This symposium is focused particularly on the dynamical and microphysical processes determining the properties of cumulus clouds and how they interact with the environment. Contributions are welcome on a range of relevant topics including aerosol-microphysics-dynamics interactions, precipitation development in cumulus clouds, entrainment and detrainment, cloud turbulence, updraft and downdraft dynamics, the shallow-to-deep convective transition, convective-cold pool interactions, and convective organization and upscale growth. These could include perspectives from observations, theory, and/or modeling, including parameterization development.
