Boundary conditions representation can determine simulated aerosol effects on convective cloud fields

Abstract Anthropogenic aerosols effect on clouds remains a persistent source of uncertainty in future climate predictions. The evolution the environmental conditions controlling cloud properties is affected by themselves. Hence, aerosol-driven modifications can affect thermodynamic conditions, which turn could feed back to development. Here, comparing many different resolving simulations conducted with models and under condition, we show that this feedback loop strongly representation boundary model. Specifically, impacts magnitude simulated response environment aerosol perturbations, both shallow deep convective clouds. Our results raise doubts about significance previous conclusions aerosol-cloud feedbacks made based idealised conditions.
