Southwest Climate Science Center supported researcher Suraj Polade is the lead on a recent study that analyzed the ways that global climate models from the last generation of projections (CMIP3, ca. about 2006) compared to the new generation of projections (CMIP5) that have been generated more recently. Specifically the study looked to see how the two generations differed in the ways that they represented Pacific Ocean-atmosphere climate modes (e.g., ENSO and PDO) in their respective historical simulations. Improvements in the new generation were identified.
