| Research Abstract |
It conceived of the prediction system for sea-salt concentrations in consideration of land geographical feature near seashore, shoreline and bottom topography, vegetation distribution, and influence of an artificial structure, and combined the computation of advection-diffusion of sea-salt particles by use of LAWEPS data with the ocean wave simulation by SWAN. In order to harness the characteristic of LAWEPS data, the advection-diffusion model using generalized curvilinear coordinates was introduced. In order to evaluate amounts of sea-salt emission fluxes from ocean waves, the relationship between sea-salt emission fluxes and wave energy dissipation rates, an interpolating function, was inferred.
