This session will provide a forum for the presentation of the latest developments, applications, and assessment methods for ocean modelling. Modelling the ocean is a complex and increasingly sophisticated science. New discretisations and parameterisations are in constant development and the application of existing and new techniques to scenarios at vastly different scales from coastal seas to the global ocean and from single processes to complex coupled systems provides a constant stream of new challenges. Ocean simulations should then be quantitatively assessed, dynamically and with respect to available observations, in order to improve the models and quantify their sensitivities. Skill measures (integrated/local statistically-significant misfit estimates) need to take advantage of most available observations, which are very diverse and usually sparse.
Presentations are solicited covering the full range of ocean modelling and their assessment including, for example, structured and unstructured meshes, new treatments of vertical coordinates, parameterisation of mixing and subgridscale processes, discretisations and stabilisation schemes, use and limitations of various observational datasets for model assessment, oceanographic and numerical outcomes of model-observation comparisons, and observational requirements for improved evaluations of ocean simulations. Contributions are also welcome on the subject of ocean model technology such as interfaces, interoperability and standardisation, new platforms and data formats. In addition to flow models, modelling of biogeochemical processes and the ocean carbon cycle lie within the session's scope.
