RCEMIP Scientific Objectives

RCEMIP was designed to address the following three themes:

  1. What is the response of clouds to warming and the climate sensitivity of RCE?
  2. What is the dependence of convective aggregation and tropical circulation regimes on temperature in RCE?
  3. What is the robustness of the RCE state, including the above results, across the spectrum of models?

These themes are related to two of the questions raised by Bony et al., 2015 as central to a better understanding of global and regional climate changes: What role does convection play in cloud feedbacks? and What role does convective aggregation play in climate?

We recognize that the initial (Phase I) RCEMIP simulations will not necessarily be a definitive representation of the RCE state. Our vision for the evolution of RCEMIP is that the initial simulations serve as a starting point. RCEMIP presents an exceptional opportunity for the participants to explore other issues. Some topics that additional simulations could address are: (1) Robustness of RCE results to experimental design; (2) Sensitivity to the model physics and dynamics; (3) Mechanisms of convective aggregation; (4) Impact of ocean-atmosphere interactions; (5) Impact of rotation.

RCEMIP Phase II is designed to build on the success of Phase I while providing a constraint on convection and circulation (and a hopefully narrower intermodel spread), and thus the motivating science questions are similar to Phase I, geared towards further investigation of cloud-circulation coupling, convective aggregation and climate. Further information on the motivation for Phase II can be found in the Phase II protocol document - coming soon!
