CLIMATE OF THE 21ST CENTURY

Objective

To compare, improve and apply well established coupled Ocean-Atmospheric General Circulation Models (O-A-GCM) for modelling of anthropogenic climate change and natural climate variability.

In sub-project 1, numerical integrations will be carried out with coupled O-AGCMs over periods of several decades to more than a century to compute the time dependent evolution of climate for a number of prescribed scenarios describing the possible evolution of future concentrations of the principal greenhouse gases (CO2, methane, CFCs, ozone, N2O).
A major goal of sub-project 2 is the investigation of the predictability of climate in the time scale range of a month to a few years. This will be studied primarily by means of coupled O-A-GCMs experiments. The prediction experiments will be accompanied by extensive sensitivity experiments to clarify the nature of predictability and to attempt to extend the predictability limit. The investigations will concentrate on the ENSO phenomenon in the tropical belt, but will include also ocean-atmosphere interactions on a global scale.
In sub-project 3 sensitivity experiments are planned with A-GCMs to test the dependence of the model on different parameterizations of critical processes (radiation, clouds, land surfaces, etc.).
Sub-project 4 concerns model intercomparison and validation. A specific set of experiments will be designed with the sole purpose of identifying discrepancies and similarities between the many different atmospheric and ocean GCMs used in the project.
In sub-project 5 the nested high resolution limited area model HIRLAM developed by the Scandinavian and Dutch weather services for Europe will be made available and operated in conjunction with the global models used in other sub-projects. The HIRLAM model will be applied in all climate experiments requiring an enhanced higher resolution representation of the climate change in Europe.
