2) multi-island
多岛屿地形
1.
In order to describe complex multi-island terrain and coastlines adequately in modelling ocean wave,an algorithm making use of high-resolution bathymetry and coastline data to optimize the design of wave computation grid and taking sub-grid terrain effect into account is developed in archipelago.
通过理想试验和实际应用表明:采用该方法后,在计算网格分辨率水平上,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。

补充资料：凹多边形

凹多边形
把一个各边不自交的多边形任意一边向两方无限延长成为一直线，如果多边形的其他各边不在此直线的同旁，那么这个多边形就叫做凹多边形。
凹多边形的内角和的解，其实我们可以通过（n-2）·180来计算。实际上是把大于平角的角划分为两个角（如图）
