This post has the form of the release of a climate model. The fact that I don't think that global warming exist doesn't mean that I agree with the environmental catastrophe taking place nowadays. This model predicts that the northern hemisphere temperatures are going to fall in years to come, though if it is correct and they don't fall, perhaps we have seriously damaged environment.

Few months ago the NTUA published my postgraduate thesis in the web:

http://www.itia.ntua.gr/e/docinfo/680/

There you can see that a simple two cosine model of 251 and 265.4 years periods, very well describes the Northern Hemisphere temperatures as reconstructed by Jones et al(1998).
The 251 years period is the seasonality of the Earth synods with Venus(wich is very canonical). The 265.4 years period is the mean period of the synods of Jupiter and Mercury with Earth when at the same time Earth is in synod with Venus too(these planets bring the greatest tidal forcing to the Sun and perhaps play a key role to Solar Activity that we get back here in Earth). The meaning is that there is a difference if the solar activity is greater if it happens when we have a summer or a winter at the Northern Hemisphere here in Earth.

The interesting is that this model very well describes the high temperatures of nowadays while at the same time it's 265.4 years cosine constituent reaches its maximum around 1950 AD wich really is the maximum of the 265.4 years cycle.
Moreover this model is a frequency beat of about 4500 years period and its' hights describe the last 10000 years Northern Hemisphere temperatures of Gisp2 in Greenland(their vest). Especially if you take into consideration the Precession of the Earth axis.

welcome to the forums.

Anyway thanks for the welcome.

Happy to see you here. Do you expect any further documentation of your model?

Happy to see you too.
I am almost sure the Venus Express will bring a positive feedback. Earth and Venus are sister planets. (Everybody wants to go to Venus now! ;-))
Though I am not sure how much truth is going to be hidden in future to come. Politics play their role after major discoveries, from fuels to liberties.

Did you happen to change feelings in the meantime? It looks sound.

Hi,
I tried to move the graphs to flickr sometime ago.

"www.flickr.com/photos/12495302@N07/1306120483/"

check how well the synod graph describes the geomagnetic field oscillation( look at CLIMAX), which means that the planets drive the solar wind.

Dimitris,

I've been working on writing a program to calculate the barycenter (even with the laws of general relativity limiting gravity's speed to that of light considered) of the solar system, all eight planets included, and mapping it against sunspot records.

I know this has been done decades ago, and the scientific community dismissed the possibility that tidal forcing influences solar cycles. There's still a few believers out there though, and I'd hate to say it's impossible without doing some calculations myself.

The Wilson H-K Study looked at activity cycles of other stars similar to our sun, and found a highly variable range of solar cycles. It'd be great if we could identify any planets (or at least the most massive ones) around those stars to see if tidal forcing plays a role in their activity cycles. Something has to be driving the cycles though, whether it's mass, chemical composition, the Milky Way's intragalactic magnetic fields, or interstellar matter densities. I think the possibility of a truly random, unordered process isn't very likely.

Anyway, interesting assertions. smile.gif

Hi am_Unition,

the geomagnetic field oscillation amplitude is not the same as the sunspot record amplitude. It consists of 11 year(from sunspots) and 42-something years (from planets) etc oscillations, as far as I can tell.
am_Unition
Dimitris,

If you theorize that the planets drive the solar wind by observations of Earth's magnetic field strength, what process links the planetary positions to significantly affecting the geomagnetic field? It cannot be a direct EM influence, as the Interplanetary Magnetic Field snuffs all planetary effects; even Jupiter's massive B-field doesn't reach us here on earth.


So I'm guessing you believe one of three things:

1) A gravitational influence on Earth from other planets with a 42 year period (not sure how you obtained that particular number, your methodology would be interesting to know) has created some kind of resultant earth-mass oscillation with a similar period... similar to a "driving force" for spring systems. Naturally, this induced oscillation would cause perturbations in the core and mantle, resulting in a similar period of variance for the amplitude of the geomagnetic field strength. Surely, then, this 42 year period would be somehow reflected in the length of day variations, as observed via VLBI, if it is a gravity-induced mass oscillation.

2) Planetary magnetic fields, most notably Earth's, Jupiter's, and Saturn's, exert a significant force and influence on the IMF, which of course directs the path of the solar wind accordingly. The solar wind then couples with the Earth's magnetic field to induce a 42 year oscillation in field strength, via variations in solar wind speed and component orientations at Earth.

3) Planetary gravitational influences on the sun induce fluctuations in the solar wind and IMF via a different mechanism than solar cycles.

Any of these would be nearly muted by the ~11 year cycle of intensity from observed solar cycles though, yes?


I'm very curious as to these kinds of things, and I looked at your paper on the NTUA site, but it is all in Greek except for the abstract.

I'd love to hear more about it, and see any graphs you can provide in addition to the ones posted on Flickr.
D Poulos
am_Unition,

the study refers to (3). There is the graph of geomagnetic field oscillation of Climax Colorado where this 42-year cycle is not muted in intensity by the 11-year one(it is of significant amplitude).

Where?? All the data sets I come across from Climax Colorado are neutron counts related to GCR flux, which is moreso an indicator of the coronal field strength.

Can you link me to something?
D Poulos
Check this link.

I don't remember well the documentation but it is something like cosmic rays and geomagnetic field oscillation are coupled, if memory serves.

Very true, the correlation is similar to that of GCR flux and the coronal field... an "anti-correlation", like shown in your link.

But disentangling one from the other is quite a task since GCR's come from all directions, the coronal field strength is variable on short-term time scales in addition to the ~11 year cycle, the structure of the heliosphere is not symmetric, and irregularities in the coronal field (like those caused by sunspots) would have to be taken into account.

I can't really find any type of detailed graph with the strength of the geomagnetic field plotted against time. Obviously there is the known slow decay over the past two centuries, but any other periodic variations I don't really know about. The fact that local polarities are constantly evolving beneath us relatively quickly isn't a big help to our measurements either.

This is tough stuff huh.gif ... thanks for that link though, I'm always a sucker for real-time updates.
D Poulos

Having in mind this kind of coupling I spoke of geomagnetic field oscillation, but anyway the correct is cosmic ray oscillation. There are modern theories that connect cosmic rays with climate through cloud formation, but it is possible that they are connected through Foucault currents too IMO.

am_Unition
Oh yes, I'm very familiar with cosmic ray flux and cloud cover correlation via ion creation and the eventual formation of cloud condensation nuclei, but how would Foucault currents fit in? Do they perturb the ions enough to stimulate convection?

Now that I understand you meant cosmic ray flux oscillations all along, things make much more sense. smile.gif
