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。The refraction caused by topography and nonlinear energy transfers are takeninto account the wind input function and S. C. Wen's tbeoretical windsea spectrumin the YW-SWP sea wave numerical prediction model given by authors, so that themodel is not only suitable for deep or shal1ow water but lias a feature especiallyapplicable to chinese sea areas as well. In addition, a weighted average method oftreating the wind field has been adopted. The model results' maximum(8.5) andminimum (2.5), in Bohai Sea, relative error for the hincast significant wave heightshow that the mode1is quite reliable and accurate. The influence of refraction is notobvious beyond 20m depths, but at about 10m it can reach 30cm.
