22.1 引言 在这一章中,提出一个新的、称为离散/混合波浪预报模式,它结合了Pierson-Tick-Bear型模式和参量化模式中的某些部分。它不同于混合参量化模式,在这种模式中,整个方向谱分为各个方向传播。它也不同于PTB对源函数的处理,即在频带空间里应用一个参量的成长来模拟非线性波与波间的相互作用。在新的模式中,利用与Abaco观测一致的风-浪不稳定机制,使每一个频带都有较大的增长率,并由ε-ξ定律给出参量的参数增长（ε是无量纲总能量,ξ是无量纲风区）。 与PTB成长模式不同,此模式是以ε_1（顺风频带无量纲能量）的参量成长和平衡区为基
22.1 Introduction In this chapter, a new model called Discrete / Mixed Wave Prediction is proposed, which incorporates some of the Pierson-Tick-Bear model and the parametric model. It is different from the hybrid parametric model, in which the entire direction spectrum is spread in all directions. It also differs from PTB’s handling of source functions by applying a parameter growth in the band-space to simulate the interaction between nonlinear waves and waves. In the new model, using the wind-wave instability mechanism consistent with Abaco observations, each band has a larger growth rate and the parametric growth of the parameters is given by the ε-ξ law (ε is the dimensionless total energy , ξ is the dimensionless wind area). In contrast to the PTB growth model, which is based on the parametric growth and balance of ε_1 (downwind band dimensionless energy)
