IMPORTANT CLAIMS:
1. The Synodic (phase) cycle of the Moon precisely re-synchronises with the times of the Extreme Perigean Spring tides (EPST) once every 574.60 topical years.
2. Jupiter precisely re-synchronises itself in a frame of reference that is rotating with the Earth-Venus-Sun line once every 575.52 tropical years.
3. The orientation of Jupiter to the Earth-Venus-Sun line produce the tidal torques that act upon the base of the convective layers of the Sun which are thought to be responsible for the periodic changes in the level of magnetic activity on the surface of the Sun (i.e. the Solar Cycle).
4. The period of time required for Jupiter to precisely re-align with the Earth-Venus-Sun line in a reference frame that is fixed with respect to the stars is 4 x 575.52 = 2302 years. This is the Hallstatt cycle that is intimately associated with the planetary configurations that are driving the VEJ Tidal-Torquing model for solar activity.
5. Hence, the repetition period for strongest of the Extreme Perigean Spring tides appears to match that of the planetary tidal-torquing forces that are thought to be responsible for driving the Solar sunspot cycle.
6. The Venus–Earth–Jupiter (VEJ) tidal-torquing model is based on the idea that the planet that applies the dominant gravitational force upon the outer convective layers of the Sun is Jupiter, and after Jupiter, the planets that apply the dominant tidal forces upon the outer convective layers of the Sun are Venus and the Earth. Periodic alignments of Venus and the Earth on the same or opposite sides of the Sun, once every 0.7993 sidereal Earth years, produce temporary tidal bulges on the opposite sides of the Sun’s surface. Whenever these temporary tidal bulges occur, Jupiter’s gravitational force tugs upon the tidally induced asymmetries and either slows down or speeds-up the rotation rate of plasma near the base of the convective layers of the Sun. The VEJ tidal-torquing model proposes that it is the variations in the rotation rate of the plasma in Sun’s lower convective layer, produced by the torque applied by Jupiter upon the periodic Venus–Earth (VE) tidal bulges that modulate the Babcock–Leighton solar dynamo. Hence, the model asserts that it is the modulating effects of the planetary tidal-torquing that are primarily responsible for the observed long-term changes in the overall level of solar activity.
What makes this simple VEJ tidal-torquing model so intriguing is the time period over which the Jupiter’s gravitational force speeds up and slows down the rotation rate of the Sun’s outer layers. Jupiter’s movement of 13.00 deg. per 1.5987 yr with respect to closest tidal bulge means that Jupiter will increase the rotation speed of the lower layers of the Sun's convective zone for 11.07 yrs. This is almost the same amount of time as to average length of the Schwabe sunspot cycle (11.1 ± 1.2 yrs, Wilson, 2011).
In addition, for the next 11.07 yrs, Jupiter will start to lag behind the closest tidal bulge by 13.00 deg. every 1.5987 yrs, and so its gravitational force will pull on the tidal bulges in such a way as to slow down the rotation rate of the outer convective layers of the Sun. Hence, the basic unit of change in the Sun’s rotation rate (i.e. an increase followed by a decrease in rotation rate) is 2 × 11.07 = 22.14 yrs. This is essentially equal to the mean length of the Hale magnetic sunspot cycle of the Sun, which is 22.1 ± 2.0 yrs (Wilson, 2011).
It is important to note that, the actual torques that are applied by Jupiter to the temporary tidal bulges induced by alignments of Venus and the Earth, vary in-phase with the observed 11 year sunspot cycle.

A. The 574.6 Year Cycle in Extreme Perigean Spring Tides
Extreme Perigean Spring tides (EPST) occur when a New moon occurs at time when the Perigee of the lunar orbit points directly at the Sun or when a Full Moon occurs when the Perigee of the lunar orbit points directly away from the Sun (the latter are often called Extreme Super Moons). Figure 1 shows a schematic diagram an EPST occurring at a New Moon.

B. The Venus–Earth–Jupiter (VEJ) Tidal-Torquing Model
(A Proposed Driver of Solar Activity)
Quote from: Wilson, I.R.G.: The Venus–Earth–Jupiter spin–orbit coupling model, Pattern Recogn. Phys., 1, 147-158
Figure 3.
It is important to note that tidal bulges will be induced in the surface layers of the Sun when Venus and the Earth are aligned on the same side of the Sun (inferior conjunction), as well as when Venus and the Earth are aligned on opposite sides of the Sun (superior conjunction). This means that whenever the gravitational force of Jupiter increases/decreases the tangential rotation rate of the surface layer of the Sun at inferior conjunctions of the Earth and Venus, there will be a decrease/increase the tangential rotation rates by almost the same amount at the subsequent superior conjunction.
Intuitively, one might expect that the tangential torques of Jupiter at adjacent inferior and superior conjunctions should cancel each other out. However, this is not the case because of a peculiar property of the timing and positions of Venus– Earth alignments. Each inferior conjunction of the Earth and Venus (i.e. VE alignment) is separated from the previous one by the Venus–Earth synodic period (i.e. 1.5987 yr). This means that, on average, the Earth–Venus–Sun line moves by 144.482 degrees in the retrograde direction, once every VE alignment. Hence, the Earth–Venus–Sun line returns to almost the same orientation with respect to the stars after five VE alignments of almost exactly eight Earth (sidereal) years (actually 7.9933 yr). Thus, the position of the VE alignments trace out a five pointed star or pentagram once every 7.9933 yr that falls short of completing one full orbit of the Sun with respect to the stars by (360−(360×(7.9933− 7.0000))) = 2.412 degrees (fig. 4).
Figure 4.
In essence, the relative fixed orbital longitudes of the VE alignments means that, if we add together the tangential torque produced by Jupiter at one superior conjunction, with the tangential torque produced by Jupiter at the subsequent inferior conjunction, the net tangential torque is in a pro-grade/retrograde direction if the torque at the inferior conjunction is greater/less than that of the torque at the superior conjunction.
Figure 5.
What makes this simple tidal-torquing model so intriguing is the time period over which the Jupiter’s gravitational force speeds up and slows down the rotation rate of the Sun’s outer layers.
Figure 5 shows Jupiter, Earth and Venus initially aligned on the same side of the Sun (position 0). In this configuration, Jupiter does not apply any tangential torque upon the tidal bulges (the position of the near-side bulge is shown by the black 0 just above the Sun’s surface). Each of the planets, 1.5987 yrs later, moves to their respective position 1's. At this time, Jupiter has moved 13.00 deg. ahead of the far-side tidal bulge (marked by the red 1 just above the Sun’s surface) and the component of its gravitational force that is tangential to the Sun’s surface tugs on the tidal bulges, slightly increasing the rotation rate of the Sun’s outer layers.
Interestingly, Jupiter’s movement of 13.00 deg. per 1.5987 yr with respect to closest tidal bulge means that Jupiter will get 90 deg. ahead of the closest tidal bulge in 11.07 yrs. This is almost the same amount of time as to average length of the Schwabe sunspot cycle (11.1 ± 1.2 yrs, Wilson, 2011). In addition, for the next 11.07 yrs, Jupiter will start to lag behind the closest tidal bulge by 13.00 deg. every 1.5987 yrs, and so its gravitational force will pull on the tidal bulges in such a way as to slow down the rotation rate of the outer convective layers of the Sun. Hence, the basic unit of change in the Sun’s rotation rate (i.e. an increase followed by a decrease in rotation rate) is 2 × 11.07 = 22.14 yrs. This is essentially equal to the mean length of the Hale magnetic sunspot cycle of the Sun, which is 22.1 ± 2.0 yrs (Wilson, 2011)."
C. The 575.52 year Realignment Cycle for Jupiter in a Reference Frame that is Rotating with the Earth-Venus-Sun Line
The slow revolution of the Earth-Venus-Sun alignment axis can be removed provided you place yourself in a framework that rotates by 215.5176 degrees in a pro-grade direction [with respect to the fixed stars] once every 1.59866 years. In this rotating framework, Jupiter moves in a pro-grade direction (with respect to the Earth-Venus-Sun line) by 12.9993 degrees per [inferior conjunction] VE alignment.
Figure 6 shows the position of Jupiter every VE alignment (i.e. 1.59866 years) in reference frame that is rotating with the Earth-Venus-Sun alignment line. This keeps the Earth and Venus at the 12:00 o'clock position in this diagram whenever the number of VE aligns is even and at the 6:00 o'clock position whenever the number of VE aligns is odd. In contrast, Jupiter starts out at JO and moves 12.9993 degrees every 1.59866 years, taking 11.07 years to move exactly 90 degrees in the clockwise (pro-grade) direction and 11.19 years to the position marked J7 (at roughly 91 degrees).
Figure 6.
Also shown on this diagram is the position of Jupiter after 27, 28 and 29 VE alignments. This tells us that Jupiter completes exactly one orbit in the VE reference frame once every 44.28 years (= 11.07 years x 4), with the nearest VE alignment taking place at 28 VE alignments (= 44.7625 years) when Jupiter has moved 3.9796 degrees past realignment with its original position at JO.
The following table shows how Jupiter advances by one orbit + 3.9796 degrees every 28 VE alignments until the alignment of Jupiter with the Earth-Venus-Sun line progresses forward by 13 orbits in the VE reference frame plus 51.7345 degrees. This angle (see * in table) is almost exactly equal to the angle moved by Jupiter in 4 VE aligns (i.e. 4 x 12.99927 degrees = 51.9971 degrees).

364________4731.7345______13__+__51.7345__*
This means that Jupiter returns to almost exact re-alignment with the Earth-Venus-Sun line after:
(364 - 4) VE aligns = 360 VE aligns = 575.52 years
[i.e. 12.9993 orbits of Jupiter in a retro-grade direction in the VE reference frame, falling 0.2625 degrees short of exactly 13 full orbits]
APPENDIX
The Planetary Connection to the 2300 Hallstatt Cycle
It has long been recognised that there is a prominent 208 year de Vries (or Suess) cycle in the level of solar activity. The following blog post shows that the there is a 208.0 year de Vries cycle in the alignment between the times that Perigee of the Lunar orbit points directly at the Sun and the Earth's seasons provided that you measure the alignment in a reference frame that is fixed with respect to the Perihelion of the Earth's orbit:
http://astroclimateconnection.blogspot.com.au/2016/05/there-is-natural-208-year-de-vries-like.html
Its appearance, however, is intermittent. Careful analysis of the Be10 and C14 ice-core records show that the de Vries cycle is most prominent during epochs that are separated by about 2300 years (Vasiliev and Dergachev, 2002). This longer modulation period in the level of solar activity is known as the Hallstatt cycle (Vitinsky et al., 1986; Damon and Sonett, 1991; Vasiliev and Dergachev, 2002).

Jupiter in a Reference Frame that is Fixed with Respect to the Stars
Figure_A1 shows the orbital position of Jupiter, starting at (0,1), every 0.79933 years, over a period of 35.9699 years [i.e. just over three orbits of the Sun]. It is clear from this diagram that, in a reference frame that is fixed with respect to the stars, the symmetry pattern perfectly re-aligns after moves roughly 24.26 degrees in a clockwise (pro-grade) direction. It takes Jupiter 71.9397 years (i.e. just over six orbits of the Sun or 45 VE aligns) to move 23.30 degrees in a clockwise (pro-grade) direction, to approach with one degree of producing a re-alignment of rotational symmetry.
Figure_A1
Figure_A2 shows the precise alignments Jupiter with the Earth-Venus-Sun line at 575.5176 years (360 VE aligns) and 1151.0352 years (720 VE aligns) in a frame of reference that is fixed with respect to the stars. Jupiter lags behind the VE alignments by 0.2654 degrees and 0.5251 degrees, respectively.
Figure_A2
Figure_A3 shows the precise alignments of Jupiter with the Earth-Venus-Sun line at 1726.5528 years (1080 VE aligns) and 2302.0704 years (1440 VE aligns) in a frame of reference that is fixed with respect to the stars. Jupiter lags behind the VE alignments by 0.7876 degrees and 1.0502 degrees, respectively.
Figure_A3
Hence, the period of time required for Jupiter to precisely re-align with the Earth-Venus-Sun line in a reference frame that is fixed with respect to the stars is 2302 years. This is the Hallstatt-like cycle that is naturally found in the planetary configurations that are driving the VEJ Tidal-Torquing model for solar activity.

Re-aligning the Movement of Jupiter in the Rotating VE Reference Frame with its Movement in the Reference Frame that is Fixed with the Stars
Figure_A2 shows the precise alignments Jupiter with the Earth-Venus-Sun line at 575.5176 years (360 VE aligns) and 1151.0352 years (720 VE aligns) in a frame of reference that is fixed with respect to the stars. Jupiter lags behind the VE alignments by 0.2654 degrees and 0.5251 degrees, respectively.
The important point to note is that after four precise Jupiter alignments of 575.5176 years (i.e. 4 x 575.5176 = 2302.07 years), the position of Jupiter advances from its initial position at JO (see figure 6 and figure_A1 above) by 24.2983 degrees. This angle is almost exactly the same as 24.26 degrees of rotation that is required to produce a re-alignment of the rotational symmetry of Jupiter, in the reference frame that is fixed with respect to the stars.
Hence, the period of time required for Jupiter to precisely re-align with the Earth-Venus-Sun line in a reference frame that is fixed with respect to the stars is 2302 years. This is the Hallstatt-like cycle that is naturally found in the planetary configurations that are driving the VEJ Tidal-Torquing model for solar activity.

Fascinating read, thank you. Living on the coast, tides are of interest to us. In 2015 we experienced a spectacular proxigean high tide coinciding with a lunar eclipse.
ReplyDeleteIs there a website listing extreme tides when these events occur together:
a) Earth is closest to the sun,
b) Moon is closest to earth,
c) Solar or lunar eclipse.
What other factors influence higher than normal tides? I know of the oscillation period of water in False Bay (South Africa) and storm winds. Any others?
