In spite of the important role convection plays in the climate system, many uncertainties remain owing to the wide variety of processes and scales involved. Processes on the smallest scales of turbulence and microphysics connect through dynamics and radiation to both weather and climate, locally through precipitation and hazardous weather, and more broadly through feedbacks on global circulations and the climate system. Improving our understanding of clouds and convection at a process level, their representation in large-scale models, and the ability to forecast related hazards remains an outstanding challenge. This session aims to explore aspects of boundary layer, shallow, and deep convective clouds, considering fundamental processes as well as links to self-aggregation, land surface interactions, and their role in weather and climate. We invite presentations of both observational and modeling studies.
