简要回顾当前第三代海浪模式中的困难。为避开这些困难，作者提出一种新的海浪模拟方法，其中特定定义的风浪组成波依常风下随时间成长的方向谱计算，而涌浪组成波藉考虑涡动黏性和底摩擦加以计算。并进行了常风场和变风场下系统的数值试验。在常风速情形中，模拟结果能精确地化为建立模拟所根据的谱和风浪成长关系。计算显示出台风中心附近浪场的极端复杂的谱结构。当风速骤然降低时，模拟的波高减小与观测符合。在风向逐渐或骤然改变情形下，计算的时间响应尺度与海上观测符合，而且演化中的二维谱结构得到良好刻画。对于涌浪在无风下的传播，模拟结果合理，包括波参量及谱结构的变化。后报得到的波高、周期和海上资料符合。与第三代模式相比，文中提出的方法较易改进，需用的计算机时间显著减少。最后讨论采用一个已知谱来建立谱形式的海浪预报模型的合理性以及有关的问题。
Briefly review the current difficulties in the third generation of wave patterns. In order to avoid these difficulties, the authors propose a new wave simulation method in which the waves of a specific definition form the direction spectrum of the waves growing with time under normal winds, and the wave composition of the waves is calculated by considering the vortex viscosity and the bottom friction Calculate. The numerical experiments of the system in the wind field and the wind field were carried out. In the case of constant wind speed, the simulation results can accurately be used to establish the relationship between the spectrum and storm growth based on which the simulation is based. Computation shows the extremely complex spectral structure of the wave field near the typhoon center. When the wind speed suddenly decreases, the simulated wave height decreases in line with the observations. In the case of a gradual or sudden change of wind direction, the calculated scale of time response is consistent with the observations at sea, and the evolving two-dimensional spectral structure is well characterized. For the wave propagation under no wind, the simulation results are reasonable, including the changes of wave parameters and spectral structure. After the newspaper reported the wave height, cycle and sea data line. Compared with the third generation model, the method proposed in the paper is easier to be improved and the computer time required is significantly reduced. Finally, we discuss the rationality of using a known spectrum to establish a spectral form of the ocean wave prediction model and related problems.
