Numerical models of the Earth System and its components are used extensively for both operational services and Earth system sciences including long term climate simulations. For the atmosphere and the oceans such models are composed of a fluid dynamics component (the dynamics) and a subgrid scale parameterization package (the physics). New numerical techniques are being developed to improve the accuracy and efficiency of these models and also new parameterizations are continuously being developed.

This session encompasses the design, testing, and application of new numerical methods for NWP and Earth System models. This includes new developments in advection schemes, shallow water models, vertical discretization, dynamical cores, adaptive meshes, test cases, physics-dynamics coupling, global and regional climate models, and parameterization of various processes in such models not covered in other sessions.
