This graph is the same as above, but all quantities have the sign removed (mathematical absolute):
Once again the 'waves' seem to shift phase with regard to the sunspot cycle, with no obvious link between them. |
Hi Carl
you are right that there is no obvious link between the two.
The
non-obvious link is that the spectrum of the two have a set of very similar periods in them as I have shown. As I have stated, the result does not give you a good correlation with the Sunspot numbers unless an additional assumption is made. That assumption is that there is a natural resonance of 10.5 years in the Sun with quite a high Q factor. Then it is possible to get a correlation of 0.66 with the sunspot numbers.
I began to make a spreadsheet to try an demonstrate this to you. However yesterday I bought some extra memory for my computer and when I installed it my computer stopped working and stayed that way after I took it out. I took in in for repair today (Saturday in NZ) but I won't get it back until Monday at the earliest. As I also mentioned, I will be away from Wednesday morning until the thread finishes, so suddenly the time has got squeezed.
At present I am logging in from another computer but I don't have ready access to all my files, so will do the best that I can to answer any further questions.
One note about the sign removal Carl - it is only the displacement that should have the sign removed.
