Abstract

<abstract abstract-type="main" id="asl2472-abs-0001"> <title>Abstract</title> <p id="asl2472-para-0001"> <bold>To explore both the parametric and structural uncertainties of climate sensitivity (CS), we have proposed a new general circulation model (GCM) ensemble termed the multi‐parameter multi‐physics ensemble (MPMPE). We used eight multi‐physics ensemble (MPE) models in which the MIROC5 physics schemes were replaced by those of MIROC3. MPMPE consisted of perturbed‐physics ensembles in which the parameter values were swept for each MPE model. MPMPE resulted in a wide range of CS, which was related to the shortwave cloud feedback (SWcld). Coupling between low‐ and mid‐level clouds controlled the differences in the parametric spread of SWcld among the MPE models.</bold> </p> </abstract>
