Description |
Numerical methods in fluids Description of regional oceanic models (primitive equations, discretization, advection schemes, parameterizations, boundary conditions). Familiarization with modelling through practical work (implementation on a simple real case, results analyses, sensitivity studies to schemes and parameterisations, process studies, comparison with observations) |
