Oscillon dynamics and rogue wave generation in Faraday surface ripples

Phys Rev Lett. 2012 Sep 14;109(11):114502. doi: 10.1103/PhysRevLett.109.114502. Epub 2012 Sep 14.


We report new experimental results which suggest that the generation of extreme wave events in the Faraday surface ripples is related to the increase in the horizontal mobility of oscillating solitons (oscillons). The analysis of the oscillon trajectories in a horizontal plane shows that at higher vertical acceleration, oscillons move chaotically, merge and form enclosed areas on the water surface. The probability of the formation of such craters, which precede large wave events, increases with the increase in horizontal mobility.
