Charvatova's Solar Inertial Motion (SIM) hypothesis - similar SIM curves yield similar solar activity

An exciting twist to a 150-year model for solar activity has been presented by Ivanka Charvatova of the Institute of Geophysics in Praha, the Czech Republic. While she still works on physics based models to establish a link between sun-barycenter movements (as have many others), she has proposed that periods of similar SIM curves would have similar solar activity. This gives a simple but powerful, phenomenlogically uncommitted way of testing for a correlation between SIM and solar activity, beyond past approaches.

Given the limited amount of sunspot data (~300 or 400 years, with quality data for only 150 years, and a basic SIM period of 178 years), there are only a couple of periods that have been compared, and the results are striking. Phasing is especially good, and the current years and projections are covered.

I think that Charvatova's approach has great potential.


Charvatova's own papers and presentations

Unfortunately, due to copyright restrictions I can't post CHarvatova's publications, but I can post presentations and a list of her publications. Here's an Aug08 presentation on Solar Inertial Motions and climate. One slide shows the near exact correspondance of Fourier and power spectrum periodicities / frequencies for SIM and values for climate. But floods, volcanoes etc are also covered!

Here's the list of Charvatova's publications:

Solar activity, climate and history over the last 7 ky using Charvatova's hypothesis and radiocarbon dating curves

Will we be able to forecast solar activity 3,000 years into the future?? Probably not with what we have at hand, but we can try.

21Aug08 - This paper and its supporting files are in a very incomplete, preliminary draft. However, Figure A.2 in Appendix A is especially interesting, as it suggests at least a "phase synchronization" between Solar Inertial Motion (SIM) and solar activity, with the 2,402.2 year Charvatovan "long cycle".

Here's a nice one-page chart to show the essence of the radio-isotope (solar activity) relation to Charvatova's 2.4 ky period of Solar Inertial Motion (SIM). It's best to print it out on 11 inch by 17 inch paper or larger (3 feet by 4 feet is even better!):

Here's a 3 foot by 4 foot chart of data folded and bent according to the Charvatovan "long" (2.4 ky) cycle, including isotope data, temperature, and history timelines.

I also need a better temperature series, such as Loehle's over the last 2 millenia, but extending back 7 ky. By the way, looking at these charts, what do YOU think it implies for climate over the next 100 years? ...And hopefully by 31Oct08 I'll post the "time folded and bent" chart of history (this could be messy).

Independent verification of Charvatova's results

I have prepared an initial draft verification of the SIM curves by Charvatova, plus I've provided some related comments, such as the lack of a correspondence between Usoskin/Solanki decadal beryllium 10 curves for periods of similar SIM.
