根据西太平洋赤道海域秋季实测海浪资料,分析了该海域的混合浪特征,拟合出混合浪的波高、周期分布函数及波高-周期联合分布函数。应用文圣常等提出的深水风浪谱公式,对其稍作改变后拟合涌浪谱;应用他们的改进理论风浪谱公式拟合风浪谱,两分谱公式叠加为混合海浪谱公式。对混合海浪谱的拟合表明,拟合效果良好。 According to the measured data of the ocean waves in the equatorial Pacific Ocean in the autumn of the western Pacific Ocean, the characteristics of the mixed waves in this area are analyzed, and the wave height, period distribution function and wave height - period distribution function of the mixed wave are fitted. Applying the formula of deep water wave spectrum proposed by Wen Shengchang et al., The wave spectrum is modified after it is slightly changed; and the wind wave spectrum is fitted by using their improved theory wind wave spectrum formula, and the bisection spectrum formula is added to the mixed wave spectrum formula. The fitting of the mixed wave spectrum shows that the fitting effect is good.
