由于南海海域地形复杂,岛屿众多,不可避免的会产生折射、变浅、绕射、波浪破碎、非线性波相互作用等近岸物理过程。因此采用以风场驱动的第三代海浪数值模式SWAN,可得到南海海域1986年1月至2005年12月较高分辨率的波浪场,计算了南海海域的波浪能流密度,综合考虑能流密度的大小和14个站位能流密度分级统计的特征等方面对南海海域波浪能资源进行了研究,寻找该海域波浪能资源的相对优势区域,为建立海上波浪能电站提供科学依据。
Due to the complex terrain of the South China Sea and the large number of islands, inevitable coastal physical processes such as refraction, shallowing, diffraction, wave breaking, nonlinear wave interaction and the like are inevitable. Therefore, using the third-generation numerical model SWAN driven by wind field, the wave field with high resolution in the South China Sea from January 1986 to December 2005 can be obtained and the wave energy density in the South China Sea can be calculated. Considering the energy flow Density and size of 14 stations, the energy resources of the South China Sea were studied, and the relative advantage of the wave energy resource in the sea area was searched for providing a scientific basis for the establishment of offshore wave power station.
