Peregrine breather solution of the nonlinear Schrödinger (NLS) equation can be treated as one of the excellent backbone models for abnormal wave in the ocean. Fully nonlinear numerical simulations performed with the higher-order spectral method reveal that its maximum amplification factor can be larger than the theoretical prediction in the regular background wave and that such breather dynamics has a high probability to persist even in a chaotic environment. Evidently, in both cases the maximum wave height attainable and the corresponding spatial evolutionary distance required are significantly affected by the initial background waves. In fact, whether the abnormal wave induced by breather dynamics can be generated, is mainly a localized behaviour, strongly dependent on the initial wave group energy as well as the detailed structure of this group.

非线性Schrödinger（NLS）方程的游廊通气解可被视为海洋异常波的优秀骨干模型之一。用高阶谱方法进行的完全非线性数值模拟表明，其最大放大因子可以大于规则背景波中的理论预测值，并且即使在混乱的环境中，这种呼吸动力学也很可能持续存在。显然，在两种情况下，可获得的最大波高和所需的相应空间演化距离都受到初始背景波的显着影响。实际上，是否可以产生由呼吸动力学引起的异常波，主要是局部行为，这在很大程度上取决于初始波组的能量以及该组的详细结构。
