Elucidation of the occurrence mechanism of freak waves via strongly nonlinear wave group solutions

阐明海洋“异常浪”的发生机制，是船舶安全航行所需要的。在本研究中，我们旨在从强非线性波群的相互作用中获得关于异常波现象的新信息。遗憾的是，在完全实现这一目标之前，研究期就结束了，但在研究过程中，我们对非线性随机波场中分量波振幅波动的特征获得了各种有意义的结果，这应该与进一步理解异常波现象有关。

Elucidation of the occurrence mechanism of "freak waves" in the ocean has long been desired for safe navigation of vessels and ships. In this study, we aimed at obtaining new information on the phenomenon of freak waves in terms of interactions of strongly nonlinear wave groups. Unfortunately the research period ended before fully achieving this goal, but in the course of the research, we have obtained various significant results on the characteristics of amplitude fluctuations of component waves in a nonlinear random wave field, which should be relevant to further understanding of freak wave phenomenon.
