To approach with numerical models is essential for grasping the mechanism of marine environment change and predicting the one in the future. We have suggested that the simulation driven by real external changing forces is important in discussing environment change with models. Especially, we have considered the reproducibility of the model for coastal zone phenomena and improved its accuracy.(Literature.2)
Also we developed Multi-Scale Ocean Analysis Model by combining the hydrostatic approximation model and the non-hydrostatic approximation model with multi-stage Nested-grid for the purpose of analyzing multi-scaled phenomena in the ocean simultaneously.
With this model, we can do relatively accurate calculation of the wide-area flow field with low computation load including the sectional flow field in such areas that the hydrostatic approximation is not available(ex. around the stracture). This model is expected to be applied for a broad range of Science and Engineering(ex. Evaluation of the technology to promote vertical mixing for improving and controlling the environment, Analysis of the natural phenomenon involving the strong convection flow by the effect of complicated terrain or the buoyancy(Literature.3).
