Abstract. A set of coupled ocean-atmosphere simulations using state the art climate models is now available for Last Glacial Maximum and Mid-Holocene through second phase Paleoclimate Modeling Intercomparison Project (PMIP2). This study presents large-scale features simulated climates compares new model results to those atmospheric from first PMIP, which sea surface temperature was prescribed or computed simple slab ocean formulations. We consider change, pointing out some major differences between different sets experiments. show in particular that systematic PMIP1 PMIP2 are due interactive ocean, such as amplification African monsoon at change precipitation mid-latitudes LGM. Also general better agreement with data than simulations.
