Coupled Climate Model Appraisal: A Benchmark for Future Studies

@article{citeulike:3040701, abstract = {Studies of future climate scenarios, such as those conducted in support of the Inter-governmental Panel on Climate Change (IPCC, http://www.ipcc.ch/), rely heavily on numerical experiments performed with coupled ocean-atmosphere general circulation models (OAGCMs). In order to assess the results of such climate change experiments, a benchmark for evaluating model performance is required. To provide this benchmark, Lawrence Livermore National Laboratory's Program for Climate Model Diagnosis and Intercomparison (PCMDI) conducted an extensive appraisal of multidecadal climate simulations by 11 coupled OAGCMs that were developed during the period of 1995-2002 [Bader et al., 2004]. While diverse representations of atmostphere, ocean, sea ice, land, and of their respective couplings were employed (see Table 1), all of these climate models were run with current values of solar and greenhouse gas radiative forcings. Thus, by comparing details of the OAGCM simulations with analogous facets of climate observations, the needed model-performance benchmark can be obtained. If, for instance, a model simulation closely replicates the salient features of the present climate, a necessary (though not sufficient) condition is met for placing some confidence in the model's projections of the climate of the next several decades.}, author = {Phillips, Thomas J. and Achutarao, Krishna and Bader, David and Covey, Curtis and Doutriaux, Charles M. and Fiorino, Michael and Gleckler, Peter J. and Sperber, Kenneth R. and Taylor, Karl E. }, citeulike-article-id = {3040701}, journal = {Eos, Transactions}, keywords = {climate, coupled, gcm, intercomparison, model, projections, skill}, number = {19}, pages = {185+}, posted-at = {2008-07-24 18:03:28}, priority = {2}, title = {Coupled Climate Model Appraisal: A Benchmark for Future Studies}, volume = {87}, year = {2006} }
