Circumstances affecting the water figures.

Energy exchanges.
.1 Probably the main variable is the amount of the energy exchanges, that are allowed to take place per unit of time, necessary to the configurational reactions.
.2 These energy exchanges take place above all as heat exchange.
.3 That is facilitated, among other things, by the water flowing: when, in a lagoon, the water is at its lowest level and at a standstill, the water figures usually either are negligible, or do not occur, even if all the other variables are at their maxima.
Slow variation of the lunar phase velocity.
.4 The second factor considered is the variation of the angular moon phase velocity.
.5 The slower the variation, the better. Which usually occurs near the points a, b, c, d of the sidereal month.
See the calendar of the lunar phase velocity in the “insert c”.
.6 This condition would enhance the units of time available, for the configurational reactions, to take place per single discrete value, of the lunar phase velocity.
Phenomenon seen at a slow motion.
.7 This allows also that everything can be seen at a slow motion, and appreciate the alternation of stretches of time - say, of 5 or 15 minutes each - where nothing special appears to take place, with others, where peculiar phenomena become visible.
.8

It is as if only some of the discrete values of angular velocity of the Moon with regard to the Earth are “useful”, with respect to the configurative state of the water at a given moment, and trigger some configurational changes.

Example: 2007 march 24 (near a “point b”).
Lusenzo 2007-03-24 u0600, Moon phase velocity deltin 366,6015; variation <+0,0191.

Positions of the generating celestial bodies.
.10

The water figures would have also a relation with the positions of the two generating celestial bodies (Moon, and Sun).

The spatioles, areas where the action is best focused.
.11 The water figures - though they may appear at all times, when all constraints are fulfilled - are more probable, and better outlined, in the places with regard to which the Moon (or the Sun) reaches given positions.
.12 These positions are here called spatioles, mobile spots within a tide basin, where the action of each generating mass (Moon, or Sun) is best focused.
See more on “the tide spatioles” (page 5.2).
Time windows.
.13 It is possible that there are a sort of “time windows”, short time spaces, normally fixed, specific to each locality, during which the water figures are more likely to assume orderly patterns.
See more on the subject “time windows”.
