Scafetta Launches New Paper Covering Planetary Influence over Solar Output Across the Holocene.

Dr. Nicola Scafetta has been very busy with another paper accepted today in the Journal of Atmospheric and Solar-Terrestrial Physics.

The new paper is titled "Multi-scale harmonic model for solar and climate cyclical variation throughout the Holocene based on Jupiter–Saturn tidal frequencies plus the 11-year solar dynamo cycle" and can be found at:

I have only read the paper once but some interesting concepts and observations are revealed. The bulk of the paper is concerned with the harmonic influence of Jupiter and Saturn.

Nicola through his analysis notes that on the sunspot cycle length data collected since the 1700's there are no cycle lengths between 10.55 and 11.25 years, with a double bell curve showing all cycle lengths each side of these values. If the solar cycle length is controlled by a random solar dynamo it is unusual that we have not had one cycle between 10.55 and 11.25 years. This suggests some form of outside control? Nicola shows how the Jupiter/Saturn tidal forces influence the spread of cycle lengths measurements.

The major thrust of Nicola's paper is the planetary influence of solar output over the Holocene. Nicola uses the modulation of Jupiter/Saturn tidal forces as the main influence over solar output over the Holocene, including solar grand minima that we are familiar with such as the Oort, Sporer, Wolf, Maunder and Dalton minima. He also includes the period between 1900-1920 which also experienced low solar cycles. Tidal forces that control solar output is a different theory than that proposed on this website, but it may be found that many principles throughout the solar system are linked. I have not yet got my head around the exact process involved in the modulation of the Jupiter/Saturn tidal force, but perhaps there is a Neptune/Uranus connection.

Readers are invited to comment on any aspects on Nicola's paper.
