SW CSC Supported Publication on Last Generation and New Generation Climate Models


06/19/2013

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.

This publication was produced as a part of the SW CSC FY 11 project "Climate change impacts in the Southwest: An assessment of next generation climate models for making projections and derivations".

The first published product of his work is now available online as:

Polade, S.D., Gershunov, A., Cayan, D.R., Dettinger, M.D., and Pierce, D.W., 2013, Natural modes of variability and their teleconnections over the Pacific-North American region in CMIP3 and CMIP5 models: Geophysical Research Letters, 40, 6 p., doi:10.1002/grl.50941.
