Global climate models (GCM) spanning a wide range of complexity are able to reproduce present day climate quite well. A wealth of studies demonstrating their competence for present and future predictions has been outlined in the Intergovernmental Panel on Climate Change, AR4. Current research efforts with GCM are moving beyond global prediction to focus on the resolution and characterisation of regional and local climate behavior. These efforts include computational science to enable fine scale models to run on leadership-class computing facilities, numerical methods to solve the increasingly multiscale and coupled equations, the inclusion of more complete process models that handle multiple resolutions and the transport of numerous additional tracers of chemical and moisture based variables. Supporting this wealth of activities requires constant and expanding verification and validation tools and robust reproducibility.
I will outline recent efforts to develop GCM to provide a regional and local prediction capability in tandem with strategies and challenges to maintain and expand our confidence in their results.
