Scélérate vagueness

The vague scélérates are Vague S oceanic very high, sudden and considered as very rare.

Until the beginning of the 20th century, the scélérates waves seemed to belong to the maritime folklore - until a certain number of testimonys of meeting of these waves by large modern ships, as well as oceanographical measurements, convince the scientists of the reality and the frequency of the phenomenon.

Characteristics

Contrary to the waves of tidal waves (Tsunami, in Japanese) which are flows big wavelength and which rise only with the approach of the coasts, the scélérates waves are vague recluses, of the same wavelength as their neighbors, but profile much more abrupt than that of the other waves and of which the height of the hollow to the peak is of 2,5 times the height of the vague averages. Moreover, the tsunamis are the consequence of an underwater seism, while the scélérates waves are formed " a priori " without reasons apparent. They are often described as a water wall which comes to run up against the ship, contrary to the " waves; classiques" who go up relatively soft inclined, allowing the ships to pass over.

One had recently still allotted the exceptional waves to the meeting of the wind against the current in circumstances of hurricane.

In a commonly allowed way, the waves can add their amplitude in a linear way: two waves, for example a one meter height of hollow with peak, can sporadically combine to form of it a wave which measures two meters. But these calculations seem to show that the linear undulatory phenomena do not make it possible to explain the appearance of waves higher than 15 Mr. However, these waves exist. The assumption is that the waves, while growing bigger more and more, do not follow any more one addition of the linear type. The resulting height is thus completely different from the sum of the components. The principle of superposition is not true any more.

One located scélérates waves in all the oceans of the world, that there are or not currents of surface. Their frequency of appearance opposes the generally allowed models, and their existence on the open ocean would consolidate the assumption of a possibility of behavior nonlinear of propagation of the waves. The currently allowed assumption would be that in a train of swell, the scélérate wave appears by absorbing the energy contained in its neighbors; Energy, by the nonlinear phenomenon, creates a well of potential in its propagation medium. This well traps energy and prevents it from dispersing. Would quantum mechanics assist from traditional mechanics in this phenomenon?

The scélérates waves can reach heights of more than 30 meters and pressures phenomenal. Thus, vague a 3 height meters normal exerts a pressure of 6 tonnes/m ². A billow 10 height meters can exert a pressure of 12 tonnes/m ². A scélérate wave 30 height meters can exert a pressure going up to 100 tonnes/m ². However, no ship is designed to resist such a pressure.

Detection

A team of researcher inhabitant of Madrid of the Université of Alcalá announced the creation of a Logiciel of analysis of the signals radars taken by orbital satellites.
