Dr Theodor Landscheidt & Solar Cycle Research

Over several decades until he passed away on May 20, 2004, Dr Theodor Landscheidt wrote extensively on the torque cycle of the planets in their orbits about the Sun causing a transference of angular momentum back and forth between the Sun and the planets in a quite predictable manner, and showed how it correlates quite well with both solar activity cycles and some aspects of the Earth’s climate.

Rather than rehash what is already written elsewhere, here are a couple of paragraphs quoted from the webpage So, What’s New In Our Universe? by Gary Sharp:

Since 1974 Theodore Landscheidt has made long-range forecasts of precisely defined classes of energetic X-ray flares and strong geomagnetic storms. A forecast experiment covering the period 1979 – 1985 was checked by the Space Environment Center, Boulder, Colorado, and the astronomers Gleissberg, Wöhl, and Pfleiderer. The forecasts reached a hit rate of 90 % even though solar eruptions occur at very irregular intervals. A forecast in 1984 that the sunspot activity would get weaker past 1990 also turned out to be correct. The just finished sunspot cycle (23) reached only mean level – although a panel of experts had predicted a sunspot maximum as high as in the preceding cycles. Cycle 23 did last a bit longer than Cycles 21 & 22, and in late July 2006 the first signs of the awaited Polar Reversal began, indicating the ending stages for Cycle 23.Â

Dependable forecasts of the Sun’s activity, based on solar cycles, made it possible for Landscheidt to correctly predict climatic phenomena years ahead of these events. His forecasts include the end of the great Sahelian drought; as well as a period of drought in the U.S.A. around 1999 , confirmed by a maximum in the Palmer Drought Index; the last five extrema in global temperature anomalies; the last three El Niños; and the course of the last La Niña. Extreme River Po discharges, beginning in October 2000, were predicted 7 months before the event.

You will find a page linking to all the online papers I could find by Dr Landscheidt on the sidebar – if you know of any others, please add them in a comment so I can update the list.

  1. Even though he may have been a largely self-taught Heliophysicist Dr. Landscheidt had phenomenal instincts unlike some academicians, e.g, Leif Svalgaard, who are among his steadfast detractors. Nonetheless, his cycle analysis has been substantially reproduced with the techniques of spectral analysis and CAM by Clilvred(2004), I.R.G. Wilson and may others.
    Perhaps his most controversial proposal, however, was that the sun’s orbit about the solar system barycenter produces a changing contribution to its angular momentum which in turn modulates solar activity. His conjecture that the change in sign of the contribution, at a zero in the second derivative, would somehow be incorporated as a torque the precise mode had not crystallized in his thinking prior to his death. In any event, he showed that the greatest pulses of solar activity are reliably associated with these crossings of the system barycenter by the solar center of mass (which distinguishes his thinking from Fairbridge who supposes the crossing to be associated with quiet solar behavior).
    DeJager, Versteegh(2004) criticised Landscheidt’s proposal believing it to imply a tidal force as the cause, i.e., understood in terms of Newtonian physics (due to change in sign of the contibution to solar angular momentum), but the Dr. did not specifiy the source.
    I recently ran across a paper by Tsagas(2006), which develops work begun by Thorne(1965), that might point to the second derivative zeroes in solar angular momentum due to barycentric crossings could in fact cause a perturbration by relativistic means via the Lorentz force. My conjecture is that the transit through the solar gravitaional well would induce a repulsive force at right angles to the field, i.e., the polar axis, a force Thorne indicated would be sufficient to stop the gravitational collapse of a black hole–along that axis.
    The field’s hystereisis would rigidly oppose the imposed deformation due to the transit. I believe the metallic hydogen core producing the polodal solar field would provide this hystereisis.
    While the displacement of the center of mass in Euclidian space is very small, at the outside, a millimeter, the traversal is physically real and effective.
    Whether or not my conjecture is correct, the circumstantial evidence presented by Landscheidt is overwhelming and I believe the Dr. will be found correct and has more surprises in store in other areas of his studies.

  2. Hi Carl,
    thanks for your outstanding compilation of Landscheidt’s work which is the best on the web.
    I am interested in the above mentioned Solar System Barycenter Ephemeris. Unfortunately I was not able to download it from none of the two sources/links.
    Your help will be very much appreciated.
    Best regards
    Dr. Georg Mayer

    • Dear Georg,
      if jou read this ,please cotatc me by mail,to arrange a personle meeteing in Berlin
      Best regards
      Erhard

  3. Georg,
    thanks for letting me know both the free storage site links have died – if I remember correctly, one has a strict time limit and the other expires of not used for a certain time.

    I now have access to a site where I can upload the Solar System Barycenter Ephemeris, giving it a brand new home that will not expire as long as my brother keeps the site going! 🙂

    I should be able to find the time over the next day or so to upload the ephemeris, and will let you know here when it is done.

    Regards,
    Carl.

  4. Just found your new link to the Solar System Barycenter Ephemeris … and it works fine. Many thanks, Carl. Best regards. Georg

  5. Georg,

    Sorry, but your comment got caught by the spam filter (presumably because of the links), and I did not see it there for a while, as I was busy with other things. Having approved it, hopefully the spam filter will now recognise you as a legitimate contributer!

    Thanks for those links, I’ve downloaded both and will read them soon.

    Carl.

  6. Love the site. FWIW, some folks have advocated calling the next solar minimum the “Al Gore Minimum”. I’d like to suggest that in addition to reminding them of the proper name “Landscheidt Minimum” that they be consoled with the suggestion to call the cold climate associate with it:

    “The Al Gore Cold Period” just a thought 😉

    I also suspect that it ought to be considered to be “Bond Event 0” since it fits the pattern…
