[AAS02-08] RCEMIP: Radiative Convective Equilibrium Model Inter-comparison Project
Keywords:radiative convective equilibium, cloud resolving model, general circulation model, model intercomparison project, RCEMIP
Geometry: sphere / plane (square or channel)
Domain size: Earth radius R / length=40,000 km × factor (e.g., 0.1–1.0)
Horizontal resolution: Δx = 1–10 km for explicit convection, or coarser resolution (1–2 degree) with a cumulus parameterization
Boundary condition: fixed SST (e.g., 296, 300, 304K) or a slab ocean
CO2: a current value or increased (e.g., 4×CO2)
Physics dependency: cloud microphysics, turbulence, radiation,; switch on/off of cumulus parameterization
Interactive radiation or non-interactive, with/without clouds
With or without diurnal cycle
Without rotation, or with rotation
Among a lot of varieties listed above, we will discuss the experimental design of RCEMIP, scientific targets, and how to proceed. One strength of RCEMIP is the numerous scientific questions that could be explored, such as better understanding of uncertainties of climate sensitivities and changes in clouds and circulations, or convective aggregation, associated with global warming.
