[MIS14-P22] Using a coupled AOGCM to study the Antarctic climate of the mid-Pliocene warm period
Keywords:Antarctica, Pliocene, modeling
In this study, we use the mid-resolution MIROC4m coupled atmosphere-ocean general circulation model and apply ice sheet configuration, land-sea mask and biome distribution from PRISM3 data sets, as set forth in the latest, second phase of the Pliocene Model Intercomparison Project. We conduct a series of experiments, including those which look into a range of atmospheric carbon dioxide levels given the spread in values suggested by various sources of proxy data. We show the degree of warming over Antarctica and how the precipitation responds to changes in the moisture transport.
