Sensitivity Study of Numerical Solutions of the South China Sea Ocean Model toVarious Grids Generated by Grid Generation Technique

摘要

The sensitivity of numerical solutions of systems of nonlinear flow equations(Navier-Stokes equations) to the grid used is investigated through the use of the South China Sea (SCS) numerical ocean model. The grid generation techniques are being introduced to coastal ocean modeling to study the sensitivity of numerical solutions to the grid used and to investigate the enhancement of the modeling process. One orthogonal (121 x 191) and two curvilinear nearly-orthogonal grids (121 x 191 and 151 x 241) are designed to couple with the SCS numerical ocean model. The designed grids are processed with the SOS numerical ocean model for 200 days to study the sensitivity of numerical solutions to the grid used. The solutions of the temperature and salinity fields are presented and analyzed. The
