> The findings could have implications for how offshore structures are designed, weather forecasting and climate modeling, while also affecting our fundamental understanding of several ocean processes.

Does this translate to terrestrial and deep space signals? FWIU there's research in rogue waves applied to EM waves and DSN, too

What is the lowest power [parallel] transmission that results in such rogue wave effects, with consideration for local RF regulations?

> Professor Ton van den Bremer, a researcher from TU Delft, says the phenomenon is unprecedented, "Once a conventional wave breaks, it forms a white cap, and there is no way back. But when a wave with a high directional spreading breaks, it can keep growing."

> Three-dimensional waves occur due to waves propagating in different directions. The extreme form of this is when wave systems are "crossing," which occurs in situations where wave system meet or where winds suddenly change direction, such as during a hurricane. The more spread out the directions of these waves, the larger the resulting wave can become.

Branched flow: https://en.wikipedia.org/wiki/Branched_flow :

> Branched flow refers to a phenomenon in wave dynamics, that produces a tree-like pattern involving successive mostly forward scattering events by smooth obstacles deflecting traveling rays or waves. Sudden and significant momentum or wavevector changes are absent, but accumulated small changes can lead to large momentum changes. The path of a single ray is less important than the environs around a ray, which rotate, compress, and stretch around in an area preserving way.

Are vortices in Compressible and Incompressible fluids area preserving?

(Which brings us to fluid dynamics and superhydrodynamics or better i.e. superfluid quantum gravity with Bernoulli and navier-stokes, and vortices of curl, and gravity (maybe with gravitons) if the particles are massful, otherwise we call it "radiation pressure" and "solar wind" and it also causes relative displacement)

Resonance: https://en.wikipedia.org/wiki/Resonance :

> For an oscillatory dynamical system driven by a time-varying external force, resonance occurs when the frequency of the external force coincides with the natural frequency of the system.
