论文摘要
我们研究了在表面重力波湍流反向级联反向的流氓波的统计数据。在这种统计均匀,固定和各向同性波场中,低频波是由非线性相互作用产生的,而不是由波浪制造商直接强迫。这提供了实验室实现的实现,可以说是最简单的非线性海洋状态,其中进行了长期获取并将其与理论模型进行比较。对数千个流氓波的分析表明,它们的某些特性至关重要地取决于四波谐振的相互作用,例如,大冠比二阶模型所预测的更有可能。
We investigate the statistics of rogue waves occurring in the inverse cascade of surface gravity wave turbulence. In such statistically homogeneous, stationary and isotropic wave fields, low-frequency waves are generated by nonlinear interactions rather than directly forced by a wave maker. This provides a laboratory realization of arguably the simplest nonlinear sea state, in which long-time acquisitions are performed and compared with theoretical models. The analysis of thousands of rogue waves reveals that some of their properties crucially depend on four-wave resonant interactions, large crests being for instance more likely than predicted by second-order models.
