海洋中的流氓波的传统定义是，它们的高度，从波峰到波谷，是有效波高的两倍以上，有效波高是附近最大的三分之一波的平均波高。当使用非线性薛定谔方程模拟深水波时，最有可能满足此标准的候选者是所谓的Peregrine解。它在空间和时间上都是局部的，因此描述了一个独特的波事件。到目前为止，专门设计用于观察深水波演化中呼吸状态的实验从未在这种双重限制下进行过。在目前的工作中，我们提出的第一个实验结果与观察的游隼孤子在水波槽。
The conventional definition of rogue waves in the ocean is that their heights, from crest to trough, are more than about twice the significant wave height, which is the average wave height of the largest one-third of nearby waves. When modeling deep water waves using the nonlinear Schrodinger equation, the most likely candidate satisfying this criterion is the so-called Peregrine solution. It is localized in both space and time, thus describing a unique wave event. Until now, experiments specifically designed for observation of breather states in the evolution of deep water waves have never been made in this double limit. In the present work, we present the first experimental results with observations of the Peregrine soliton in a water wave tank.
