Two methods for computational reconstruction of fluctuating flows in the ocean based on field measurement data are suggested. Here full-3D treatment with the spatial scale of O(100m)–O(1000m) is taken into account. In the first method, the fluctuating flow based on measurement data is generated at inflow boundary and introduced into computational domain. In the second method, small wavenumber components of fluctuation in the ocean are forced in computational domain, and large wavenumber components are generated automatically. The results of each method are discussed with comparing with measured data, and effectiveness of each method is shown.
