The waves move generally toward the west in the lower tropospheric
tradewind flow across the Atlantic Ocean. They are first seen usually
in April or May and continue until October or November. The waves have
a period of about 3 or 4 days and a wavelength of 2000 to 2500 km
[1200 to 1500 mi], typically (Burpee 1974).

Now let us perceive if we may; a 3 or 4 day interval with an uptake of
some 12 to 16 perhaps consequent to their being harmonics of a shared
algorithm.

We know that one part of the sum is the time of the phase and that it
must follow a suitable synergy. (That last part may have to fall by
the wayside in light of recent developments.) So what astronomical
phenomena are there that might give us a 3 or 4 day pattern?

Possibly something to do with Libration and mascons...

The seasonality of hurricanes tells us one series of lunar librations:

Just as the rotation axis of the Earth is inclined by (90°-23.5°) to
the Earth-Sun direction (drawing above, from section #3 "Seasons of
the year"), so the rotation axis of the Moon is inclined by about (90°-
6.5°) to the mean Moon-Earth line. As noted, that line is also the
direction of the Moon's elongation, on the average always pointed
towards Earth.

In the discussion of the seasons of the year, it was shown how the
23.5° tilt of the Earth axis lets the Sun shine onto the polar caps,
onto circular areas around the poles, giving them 24-hour sunlight.
The drawing demonstrates how in June the Sun illuminates the northern
polar cap and in December (when shade and light are interchanged) the
southern one.

In other words, as the moon presents significantly more effect on
Caribbean storms between April to October, perhaps something in its
make-up is central to the plot. (Or maybe something just a little
north by north west? What did Shakespeare know?)
