| 摘要: |
| 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。 |

| Abstract: |
| The refraction caused by topography and nonlinear energy transfers are taken into account the wind input function and S. C. Wen’s theoretical windsea spectrum in the YW-SWP sea wave numerical prediction model given by authors, so that the model is not only suitable for deep or shallow water but has a feature especially applicable to chinese sea areas as well. In addition, a weighted average method of treating the wind field has been adopted. The model results’ maximum (8.5) and minimum (2.5), in Bohai Sea, relative error for the hincast significant Wave height show that the modelis quite reliable and accurate. The influence of refraction is not obvious beyond 20 m depths, but at about 10 m it can reach 30 cm. |
