摘要:

我们的实验表明,一个稳定的波传播到一个区域的特点是相反的电流可能成为modulationaly不稳定。实验已经在两个独立的波浪水槽设施中进行;它们都配备有造波机和泵,用于产生相对于波浪在相反方向上传播的电流。实验结果支持了最近基于电流修正的非线性薛定谔方程的猜想,该方程建立了以负水平速度梯度为特征的非均匀电流可以触发流氓波。

英文摘要:

We show experimentally that a stable wave propagating into a region characterized by an opposite current may become modulationaly unstable. Experiments have been performed in two independent wave tank facilities; both of them are equipped with a wavemaker and a pump for generating a current propagating in the opposite direction with respect to the waves. The experimental results support a recent conjecture based on a current-modified Nonlinear Schrödinger equation which establishes that rogue waves can be triggered by non-homogeneous current characterized by a negative horizontal velocity gradient.
