  Information - OS16 Model development for large- and small-scale processes in the ocean (co-listed NP)

Event Information
'Recent developments in numerical models of physical and biogeochemical processes at all scales in the ocean has been rather impressive. With increasing computer power the progress in numerical techniques is expected to continue and many methods that previously were too complex or demanding have now become a real opportunity.

In physical oceanography novel methods include the choice of hybrid vertical coordinates, unstructured or adaptive meshes, combinations of finite difference, finite volume and finite element methods, advection schemes, parameterization by statistical methods just to name a few.

Better descriptions of physical transport processes have also led to improved simulations of the cycling of biogeochemical tracers. High-resolution simulations of multiple-tracer, non-linear biological systems are now possible, and the development of new parameterisations of complex food-web structures and functional groups as well as of sub-grid scale mixing of biogeochemical tracers is well under way. Validation of these increasingly complex models is now becoming a critical issue, as are observability and controllability of the model's degrees of freedom.

We solicit contributions covering any of the abovementioned topics, including those that aim to quantify the improvements brought about by the recent model developments.'
