RCEMIP: Radiative-Convective Equilbrium Model Intercomparison Project


We are excited to move towards a Phase II of RCEMIP, which will involve simulations with a prescribed analytic SST boundary condition. For more info check out: RCEMIP Simulations and the RCEMIP-II protocol paper. Registration for participating in Phase II is now open!

Radiative-convective equilibrium (RCE) is an idealization of the tropical atmosphere, in which there is a statistical balance between radiative cooling and convective heating. RCE has long been used to study basic questions in climate science, from the vertical temperature structure of the tropics and the first estimates of climate sensitivity, to the scaling of the hydrological cycle with warming, interactions between convection and radiation, and the organization of convection.

RCEMIP is a coordinated intercomparison of models configured in RCE, to include both cloud resolving models (CRMs) and general circulation models (GCMs). There are a large variety of scientific questions that could be explored with RCEMIP, but we focus on changes in clouds and convective activity with warming, cloud feedbacks and climate sensitivity, and the aggregation of convection and its role in climate. These topics are related to some of the biggest open questions in climate dynamics, as detailed by the WCRP Grand Challenge on Clouds, Circulation, and Climate Sensitivity (Bony et al., 2015). In addition to addressing these important questions, RCEMIP serves as a common baseline, enabling assessment of the formulaic sensitivity of simulations of RCE and providing a fixed point for past and future studies.
