Abstract
Some portions of the ocean surface put a troposphere column placed above them in ideal temperature and humidity training atmosphere’s low-pressure system and primary gravity waves that accompany them. This is similar to pilots that put their plane in the ideal conditions for the atmosphere to suck it and allow a successful launch. To study the behavior of rogue waves triggered by the tornadoes, cyclones or hurricanes in terms of their space and time evolution, that is, their motion and also in terms of mechanical transformations that these systems may suffer in their dealings with other systems, we use the effectiveness of Mbanes’ fluid dynamic balance model which provides relevant knowledge on the vertical profile of winds triggered by the atmosphere’s low-pressure system. Result shows that: i) the rogue waves are generated on the free surface of deep-water by constructive filamentation or interference of atmosphere’s low-pressure system and ii) the nonlinear evolution of the occurrence probability of freak wave predicted increases with the number of wave train and steepness parameter.
