7 - Precursor signs before a wave “arrival”.

===================================================

Precursor signs of normal waves.

An area of placid and unruffled water, in a lagoon, does not swell just before being affected by waves, caused by the passage of a boat.

Precursor signs before a density wave gets shape.

By contrast, in the case of density waves, the area that will be affected, the minute before they appear, is subject to various precursor processes, the most visible of which may be a swelling of the area, or a bubbling water.

Density waves in the phase of swelling.

Lusenzo, 2007-04-28 u0916: spatiole B u0848; moon declination N 1°45; Moon distance km 404490; Eq t -2'25"; moon angular velocity 104.68 deltins/hr; variation -0.04 sec/hr.. Water level: cm +10.

Operation “syntonisation”.

Around one minute before the start of the density waves, even before the swelling, one may catch a glimpse of a few warning signs, rather hard to grasp.

One cannot rule out that the density waves are just the last phase of a process of successful ... “syntonisation” to a critical frequency of motion ...

... (operation) done more or less quickly, and thus, more or less effectively, as the available time, at which a useful value is working, is always of short duration.

The efficient use of the limited available time depends on two crucial variables, here repeated, ...

(1) being near to the time of a spatiole (when the signal is stronger), ...

and (2) with enough quantity of contextual energy exchanges, those which make the configurational reactions in water molecules possible.

During the first 10 seconds, no particular event appears to be in process. Then, during around one minute, some process appears to begin, until waves of water swellings appear, and get some order, taking the shape of a grid of protuberances.
