摘　　要：针对琉球群岛海域内多岛屿复杂地形对海浪数值计算的特殊影响,发展一种综合利用水深数据和高分辨率海岸线数据优化计算网格且引入次网格地形效应的方法,并利用WAVEWATCH-Ⅲ模式进行连续1个月的数值模拟试验。结果表明:采用该方法后,在计算网格分辨率上,充分考虑了海岸和多岛屿地形对海浪传播的作用和多岛屿的次网格效应,数值计算结果有明显改善。In order to describe complex multi-island terrain and coastlines adequately for modeling ocean wave in sea areas by Ryukyu,an algorithm based on high-resolution bathymetry and coastline data was developed to optimize the design of wave computation grid and introduce subgrid terrain effect into wave computation.WAVEWATCH-Ⅲ was used to carry on continuous numerical simulation for a month.It was validated that the impact of complex coastline and multi-island on the wave propagation,computation grid resolution,and sub-grid effect of the multi-island effect was adequately address.Application of this algorithm led to much improved computational results.
