Interactions between convection and its large-scale environment during the AMIE/DYNAMO campaign are examined using doubly-periodic cloud-resolving model (CRM) simulations. The properties and upscale heat and moisture budget of different cloud types simulated under imposed large-scale forcing from the northern and southern sounding arrays and variational analyses are related to the thermodynamic environment and Madden-Julian Oscillation (MJO) phase. The relationship between convection and environmental moisture is given particular attention. In addition, the importance of CRM resolution, particularly in the simulation of shallow clouds, and microphysics parametrization is also assessed with cloud properties compared to observations from the dual-polarimetric S-band (S-Pol) precipitation radar and Ka-band Atmospheric Radiation Measurement (ARM) zenith radar (KAZR).
