Breakthroughs in ocean and climate modeling made possible by supercomputers of today and tomorrow

A three-dimensional hydrodynamic model has been constructed for the purpose of simulating ocean circulation on modern supercomputing architectures. The model is designed to take advantage of faster clock speeds, increased numbers of processors, and enlarged memories of machines expected to be available over the next decade. The model allows realistic global simulations to be conducted in support of the Global Change Program. This involves resolving the energetic scales of motion, usually referred to as 'eddies'. Such global ocean modeling is essential for proper representation of the full range of oceanic and climatic phenomena. The first-ever global eddy-resolving ocean calculation is reported as a genuine breakthrough made possible by today's supercomputers.<>
