occur tangentially to the surface of the Sun, if the gravitational

force of Jupiter were to tug upon the combined tidal bulge

that is induced in the convective layer of the Sun by the

periodic alignments of Venus and the Earth (every 1.599

years). In essence, whenever the cumulative acceleration

is increasing (i.e its slope is positive), the tugging gravitational

force of Jupiter increase the rotation rate of a layer of plasma

in the Sun's convective layer [assumed to be a dynamically

decoupled layer ~ 0.02 % of the mass of the Sun]. Similarly,

whenever the cumulative acceleration is decreasing (i.e its

slope is negative), the tugging gravitational force of Jupiter

decrease the rotation rate of a layer of plasma in the Sun's

convective layer.

N.B. It is reasonable to assume that the dynamically

decoupled layer in the Sun's convection region is likely

to be at the base of the convective zone near the

Tachocline, since this is where most solar scientists

believe that the solar dynamo is formed.

Figure 1a shows this cumulative acceleration between the

years 1880 and 1960, while figure 1b shows the corresponding

plot between the years 1950 and 2030.

Superimposed on each of these figures are the times of solar

maximum for solar sunspot cycles 13 through 23.

Figure 1a

Figure 1b

Whenever the Sun's sunspot cycles were weak, as in

the later parts of the 19 th century and the first 40 years

of the 20 th century (i.e. cycles 13 through 17), the

rotation velocity of the layer in the convective region of

the Sun changed direction PRIOR TO the date of solar

sunspot maximum.

Whenever the Sun's sunspot cycles were strong, as in

the last 60 years of the 20 th century (i.e. cycles 18

through 23), the rotation velocity of the layer in the

convective region of the Sun changed direction AFTER

the date of solar sunspot maximum.

What this suggests is that there could be a correlation

between the relative timing of the change in rotation

velocity of the layer in the convective region that is being

spun up and spun down by Jupiter's gravitational force.

Figure 2a shows the peak Solar sunspot number for cycles

-4 through 23 [covering the period from 1698 to 2009]

plotted against the number of years that the Jupiter

induced change in direction of rotation of the layer in

the convective zone, occurs BEHIND the year of solar

maximum [i.e. Solar maximum minus peak cumulative

acceleration in years].

the convective zone, occurs BEHIND the year of solar

maximum [i.e. Solar maximum minus peak cumulative

acceleration in years].

The data in figure 2a clearly shows that there is indeed

a moderately good correlation between these two

variables (R = 0.678).

Figure 2a

is that there are three solar sunspot cycles associated with

the Dalton Minimum (i.e cycles 4, 5 and 6 which are

labelled in the diagram) that are systematically shifted towards

lower left of the figure. This raises the possibility that during

periods of low solar activity like that in the Dalton Minimum,

the Sun may respond differently to the tidal-torquing of Jupiter

than at times of "normal" solar sunspot activity.

Figure 2b below, shows that if these three unusual solar cycles

are excluded from the data set, the quality of the correlation

greatly improves, with the new linear correlation co-efficient

being R = 0.784.

Figure 2b

Hence, provided we exclude the unusual solar sunspot

This is comparable to the level of correlation that exists between

the peak sunspot number for a solar cycle and the time it takes

[in years] for that sunspot cycle to reach maximum.

Figure 3 shows the relationship between the peak solar sunspot

number and the time required for that sunspot cycle to reach its

maximum for solar cycles -4 through 23. As you can see, there

is a very good correlation between these two parameters with

the correlation coefficient being R = 0.810.

Figure 3

cycles associated with grand solar minima, there appears

to be an excellent correlation between peak sunspot

number of a solar-cycle and the timing of the Jupiter induced

change in direction of the rotation rate [of a layer in the

convective zone of the Sun] compared to the timing of

solar maximum.

Peak SSN = -13.485 x (SOL MAX - PEAK of Cumulative Acceleration) + 116.05

Unfortunately, this relationship cannot be used to predict the

peak SN for the next two solar cycles, as there is a strong

possibility that both cycles 24 and 25 will be very similar to

cycles 5 and 6 in the Dalton Minimum. Evidence for this can

be seen in figure 4.

Figure 4 is a reproduction of figure 2a, with a box superimposed

on the figure showing were we expect solar cycle 24 to be

located if it reached a sunspot maximum some time between

2013 and 2014, with a peak sunspot number between 65

and 85. This places cycle 24 in similar part of the diagram as

solar cycles 5 and 6.

N.B. The relation between peak SN and the rise time of a solar

cycle [shown in figure 3] would point to a maximum for cycle 24

that is either at or after 2014, tending to favor a location for cycle

24 that is at the right hand side of the box in figure 4.

link the level of solar sunspot activity to planetary motions,

the simple V-E-J Tidal-Torquing model [that has been

presented in this blog] implicitly produces many of the

observed properties of the Solar sunspot cycle without

any need for a "phase-catastrophe" to realign the planetary

motions with the solar dynamo.
