CMIP: A study of climate variability and predictability according to general circulation models
- Lawrence Livermore National Lab., CA (United States)
The Coupled ocean-atmosphere Model Intercomparison Project (CMIP) is very briefly described, and preliminary results are presented. The goal of CMIP is to comprehensively study to behavior of global coupled models of the atmosphere, ocean, and sea ice. CMIP is presently examining control runs in which external forcing terms are held constant. CMIP has received output from 17 different coupled general circulation model control runs. For the shortest time scale examined, the seasonal cycle, the modeled surface air temperature agrees fairly well with observations. This is a nontrivial result because about half the models examined refrain from using flux correction to move their results closer to observations. Power spectra of the globally and annually averaged surface air temperature are presented, and reveal substantial differences in interannual variability among the models. 3 refs., 1 fig., 1 tab.
