YW－SWP海浪数值预报模式考虑了地形引起的折射效应和波波间非线性能量转移，采用了新的风输入源函数和文氏理论风浪谱，使模式不仅适合深浅水，且有更适合我国海区的特色;另外，计算中对风场采取了一种加权平均的处理技术。应用于渤海个例检验及对温坨子站的后报结果表明，本模式有相当好的可靠和准确性。折射效应在20m以上水深影响不明显，但在大约10m水深的浅水区影响达30cm。
YW-SWP ocean wave numerical prediction model takes into account the refraction effect caused by the terrain and the non-linear energy transfer between waves. It adopts a new wind input source function and Wen’s theory wind wave spectrum so that the model is suitable not only for deep and shallow water but also for China’s sea area In addition, the calculation of the wind field to take a weighted average processing technology. The results of the Bohai Sea case test and the post-Bo Wenhua station show that this model is quite reliable and accurate. The effect of refraction is not obvious at depth above 20m, but the influence in shallow water about 10m depth is up to 30cm.
