[MIS15-P13] CO2 sensitivity experiments to study the climate of the mid-Pliocene Warm Period: results from Antarctica and the Southern Ocean
Keywords:climate modeling, Pliocene, Antarctica, Southern Ocean, paleoclimate
In our study, we use the mid-resolution MIROC4m coupled atmosphere-ocean general circulation model and apply ice sheet configuration, land-sea mask, orography and biome distribution from PRISM data sets, as set forth in the second phase of PlioMIP. We conduct a series of experiments which include a range of atmospheric carbon dioxide levels given the spread in values suggested by different sources of proxy data and show how various aspects of the climate in the southern polar region respond. We also compare sea surface temperature anomalies with proxy values derived from PRISM data sets.
