Article Summary: This is an invited lecture dedicated to the physics behind rogue waves. Author concentrates upon the phenomenon of freak/rogue waves existing in the open ocean. How to deduce such enormous concentration of wave energy compared to the average Author analyses three main types of effects which are potential sources for the wave energy focusing…

Introduction

However, author critiques this factor as "rather unrealistic". Second factor is temporal-spatial focusing which is the result of applying dispersion to a wave group with chirped spatial distribution of frequencies. Author notes that this mechanism can work for the "forced" wavetrains only which can not develop spontaneously. Finally, third factor is nonlinear focusing which produces solitons and so-called breathers as model representations of rogue waves. About real mechanisms of the rogue waves forming in the open ocean, author concludes that 'nobody knows the answer to these questions yet.'
My Comments: This paper shows that there are some fields for researches with no direct and clear answers. Real mechanism of the rogue waves forming in the open ocean is yet unknown. Existing mathematical models for explanation of these phenomena are refined but not realistic. Indeed, considered mechanisms for the wave energy focusing are operable only for narrow sets of cases or for unnatural conditions. Details of mathematical notations (especially in Appendix) were not clear for me.
Article Summary: This is short but comprehensive introduction to the freak/rogue waves phenomenon. ...

Significant of Edge Waves and Shear Waves
Edge waves or low frequency gravity motion waves are water waves that are trapped at the shoreline by refraction. It is produce by the variability of wave energy reaching shore. An edge-wave is a low frequency wave attached to the beach. The edge waves have periods of a minute, a long-shore wave-length of around a kilometer, and amplitude that decays exponentially offshore as shown in figure 1…

Wave Theories and Their Applicability
This disturbance carries the energy and travels through the water from one location to another without or temporarily transporting the water on which the wind acts. It is like transfer of power or energy from one thing to another. The wind exerts the force on water to form the wave to carry its energy. Then where the wind energy comes from It's again recursive. It's not the topic of discussion in…
