In the previous posting the Tide Tables for Cristobal [Colón, Panama 9° 21′ 26″ N 79° 53′ 55″ W] revealed that “tidal maxima do not occur when the Moon is overhead” and that “the tidal range peaks when the Moon is at its Northern maximum and at its Southern maximum.”
Generally, the rhythm of the Lunar Orbit dictates the cycle of tides at Cristobal.
When the Moon is at its Northern [or Southern] maxima the tides display a single daily high tide. When the Moon moves closer to the Equator the tidal pattern displays two daily high tides.
The Lunar Meridian advances each day as the Moon orbits the Earth.
The advance varies from 40 minutes to 63 minutes as the Lunar orbit moves North and South.
Overall, the single daily tides adopt an average rhythm of 24 hours and 52 minutes which gives an average time between High and Low water of 12 hours and 26 minutes.
The Lunar interference to this pattern [as the Moon nears the Equator] alters the rhythm so that the time between High and Low water appears to oscillate around the quarter period of 6 hours and 13 minutes.
However, this underlying monthly pattern is regularly broken [especially in the Summer and Winter months] when the time between High and Low water spikes up to [around] 16 hours.
These curious spikes appear to be associated with [both] Full Moon and New Moon.
However, the interference spikes are different in Summer and Winter.
In the Summer months New Moon and Full Moon cause low tides.
Whereas, in the Winter months the New Moon and Full Moon are associated with higher high tides, whilst the First Quarter and Third quarter are associated with higher low tides.
This clearly suggests:
1) The Moon interferes with the Ambient Force in the New Moon and Full Moon alignments.
2) The Ambient Force is an electromagnetic force i.e. not a gravitational force
3) The Sun is the local focus of the Ambient Force.
