From techno-science.net This tip came in on our tip & notes page, and at first I was quite surprised because I could not see a possible mechanism for it. Then as I read the translation (from French) it started to make more sense. I’ll point out my friend Jim Goodridge published an essay on WUWT about correlation of the PDO and rainfall with LOD: California Climate, PDO, LOD, and Sunspot Departure
Here’s the graph from the current article of interest:
And here’s some excerpts describing possible mechanisms:
Some authors, notably Bourget et al (1992), had begun to reveal correlations between solar activity and the length of day, and more recently, Abarca del Rio et al (2003) and Winkelnkemper (2008) in his thesis noted that the amplitude of the component semi-annual (6 months period) of the length of day and atmospheric angular momentum were anti-correlated with changes in the same period of the ” solar constant (the solar constant expresses the amount of solar energy (actually a lighting power) which would be one …) “.
What could be the link between certain changes in day length, the zonal winds and solar activity? To help answer this question, The Mouël and colleagues analyzed a series of 48 years (from 1962 to 2009) of daily measurements of the length of day, the service provided by the International Earth Rotation and systems reference located at the Observatoire de Paris. They have extracted the component of period 6 months and showed significant variations in the amplitude of this component, about 30%, they compared the one hand the number of sunspots (the Wolf number, a traditional indicator of solar activity measured for several centuries) and also the flux of galactic cosmic ray.
The authors show a good correlation between these three parameters, more precisely (Figure), it is the evolution of cosmic rays and the amplitude of the semi-annual day length are correlated (correlation coefficient the order of 0.7), and are in phase. The correlation is improved when we remove the curve (In geometry, the word curve or curved line designates certain subsets of the plan, the usual space. ,…) example of day length linear trend which could be related to phenomena occurring in the nucleus. It is established also that variations in cosmic rays are out of phase with sunspots and shifted about a year (this is attributed to the mechanism of modulation of galactic cosmic rays by the solar wind (solar wind is a stream plasma consisting essentially of ions and electrons are ejected from the high …) and its magnetic field).
How the speed of rotation of the Earth can it be sensitive to the modulation of cosmic rays?
The answer is in the system of winds. Those who contribute most to the seasonal variations of angular momentum are the winds of relatively low altitude (Altitude is the vertical elevation of a place or object relative to a baseline.) below 30km . Taking an average over a year (A year is a unit expressing the duration of time between two occurrences of an event linked to the revolution …), the difference between radiation (Radiation is energy transfer under form of waves or particles, which can occur by radiation …) received from the Sun ((weight percent)) and one that is emitted by the Earth outward into the great length of wave (A wave is the propagation of a disturbance occurring on its passage a reversible variation of properties …) (IR) is positive towards the equator and negative beyond 40 degrees latitude (Latitude is an angular value, expression north-south position of a point on Earth (or another …).
This latitude gradient must be balanced by a flow of energy (in the common sense energy means anything that allows a work, making the heat, …) from the equator to the poles: the transportation (transport, from the Latin trans, beyond, and portare wearing is wearing something, or someone one, a place …) is provided by the Southern movements (that is to say along the geographic meridians) of the atmosphere, averaged in longitude (Longitude is an angular value, expressing the position east-west from a point on Earth (or another …), and eddies. The zonal winds are the result of this transport because of conservation of angular momentum: going to the poles is approached the axis of rotation of the Earth and changes in this distance must be compensated by changes in speed. The seasonal variations in insolation lead to variations of the same period of the carriage along the meridians and, from there, the mean zonal winds.
…
There is another route by which clouds can be affected: the atmosphere is indeed penetrated by a vertical electric current of a few nano-Ampere per square meter (the meter (the meter (symbol m, the Greek metron, measure) is the basic unit of length in the International System. … It is defined) square (a square is a regular polygon with four sides is a quadrilateral that is both a rectangle (it a. ..) ( symbol m) is the unit area of the international system.), which fluctuates with the ionospheric currents and therefore the solar activity. These vertical currents electrically charged clouds and, again, change their micro-physical state. Both mechanisms can indeed co-exist. What characterizes them is that those variations induced by solar activity is measured in tenths of a percent and not in parts per thousand. That’s where the important niche amplification (We are talking about force amplifier for a whole range of systems that amplify the efforts: mechanics ,…) of the phenomenon.
Thus, the Earth (specifically the mantle), the rotation is accelerated or slowed according to the fluctuations of cosmic rays under the influence of solar activity through the zonal winds, provide a wonderful device integration variations in atmospheric angular momentum and zonal wind circulation that it is difficult to measure directly.

Pour tenter de répondre à cette question, Le Mouël et ses collègues ont analysé une série de 48 années (de 1962 à 2009) de mesures journalières de la longueur du jour, fournies par le service international de la rotation de la Terre et des systèmes de référence situé à l’Observatoire de Paris. To help answer this question, The Mouël and colleagues analyzed a series of 48 years (from 1962 to 2009) of daily measurements of the length of day, the service provided by the International Earth Rotation and systems reference located at the Observatoire de Paris. Ils en ont extrait la composante de période 6 mois et ont mis en évidence de fortes variations de l’amplitude de cette composante, de l’ordre de 30%, qu’ils ont comparé d’une part au nombre de taches solaires (le nombre de Wolf, un indicateur traditionnel de l’activité solaire mesuré depuis plusieurs siècles) et d’autre part au flux de rayon cosmiques galactiques. They have extracted the component of period 6 months and showed significant variations in the amplitude of this component, about 30%, they compared the one hand the number of sunspots (the Wolf number, a traditional indicator of solar activity measured for several centuries) and also the flux of galactic cosmic ray.
Les auteurs mettent en évidence une bonne corrélation entre ces trois paramètres, plus précisément (Figure), ce sont les évolutions des rayons cosmiques et de l’amplitude de la composante semi-annuelle de la longueur du jour qui sont corrélées (coefficient de corrélation de l’ordre de 0,7), et qui sont en phase. The authors show a good correlation between these three parameters, more precisely (Figure), it is the evolution of cosmic rays and the amplitude of the semi-annual day length are correlated (correlation coefficient the order of 0.7), and are in phase. La corrélation est améliorée quand on retire à la courbe de la longueur du jour une tendance linéaire, qui pourrait être liée à des phénomènes se produisant dans le noyau. The correlation is improved when we remove the curve (In geometry, the word curve or curved line designates certain subsets of the plan, the usual space. ,…) example of day length linear trend which could be related to phenomena occurring in the nucleus. Il est établi par ailleurs que les variations des rayons cosmiques sont en opposition de phase avec les taches solaires et décalées d’environ un an (ceci est attribué au mécanisme de modulation des rayons cosmiques galactiques par le vent solaire et son champ magnétique). It is established also that variations in cosmic rays are out of phase with sunspots and shifted about a year (this is attributed to the mechanism of modulation of galactic cosmic rays by the solar wind (solar wind is a stream plasma consisting essentially of ions and electrons are ejected from the high …) and its magnetic field).
Comment la vitesse de rotation de la Terre peut-elle donc être sensible à la modulation des rayons cosmiques ? How the speed of rotation of the Earth can it be sensitive to the modulation of cosmic rays?
La réponse est dans le système des vents. The answer is in the system of winds. Ceux qui contribuent le plus aux variations saisonnières du moment angulaire sont les vents de relativement basse altitude , en dessous de 30km. Those who contribute most to the seasonal variations of angular momentum are the winds of relatively low altitude (Altitude is the vertical elevation of a place or object relative to a baseline.) below 30km . Prise en moyenne sur une année , la différence entre le rayonnement reçu du Soleil et celui qui est réémis par la Terre vers l’extérieur dans les grandes longueur d’ onde (infra-rouge) est positif vers l’équateur et négatif au delà de 40° de latitude . Ce gradient en latitude doit être équilibré par un flux d’ énergie de l’équateur vers les pôles: ce transport est assuré par les mouvements méridionaux (c’est-à-dire le long des méridiens géographiques) de l’atmosphère, moyennés en longitude , et les tourbillons. Les vents zonaux sont la conséquence de ce transport à cause de la conservation du moment angulaire: en allant vers les pôles on se rapproche de l’axe de rotation de la Terre et les changements de cette distance doivent être compensés par des changements de la vitesse. Les variations saisonnières d’insolation entraînent des variations de même période du transport le long des méridiens et, partant de là, de la moyenne des vents zonaux. Taking an average over a year (A year is a unit expressing the duration of time between two occurrences of an event linked to the revolution …), the difference between radiation (Radiation is energy transfer under form of waves or particles, which can occur by radiation …) received from the Sun ((weight percent)) and one that is emitted by the Earth outward into the great length of wave (A wave is the propagation of a disturbance occurring on its passage a reversible variation of properties …) (IR) is positive towards the equator and negative beyond 40 degrees latitude (Latitude is an angular value, expression north-south position of a point on Earth (or another …).

‘ There you go again’ (RR).
I am not interested in peer reviews (lot of those fall by the wayside), just good solid verifiable data on which I base my conclusions.
Now if you are in business of science (and displayed good old scientific curiosity) you would made an effort to find out what is the data I have used as base of my work, or alternatively you would say : ‘here is actual 10Be data file as compiled from the Greenland ice cores, compare two and let me know what the result is’.
Your determined pursuance over various web blogs is welcome, convinces me and possibly others there is something to be concerned about.
My friend ‘radun’ made it through the ‘taminos’ censorship, I might try it again, (may I see you there too?), just waiting for Dr. McCracken response if any, it appears that he has already looked at the emailed link:

Re Solar Chord Science and the n-body issue
Fred Bailey replied elsewhere:
“Lucy Skywalker mentioned in an earlier post that my work may resolve the three body problem that Newton failed to achieve. I wish it were so but regrettably it is not. In my opinion, there is only one reason why a person of his calibre could not solve that problem, and that is because it is totally unsolvable.
The problem with the n-body solution, is that no matter what computing power one has at one’s disposal, one cannot tell the computer, or indeed one’s own brain, what the original vector starting points and vector co-ordinates are at the point of conception.
Prof. Steven Hawking has just made known his thoughts on the subject of the Universe’s conception, where he states that it all began without the necessity of the help of God. It only required the presence of Gravity. ( my thoughts…..perhaps that is what God is! ). Because of this dilemma, I think that the solution of the n-body problem will never be achieved.
Having said all this, I do believe that my work is important in the short term, ie., over periods of time measured in hundreds of years, because the drift in the vector quantities over these periods will not significantly alter the patterns of the solar bodies relationships, and therefore, neither will it significantly alter the Chord dimensions that I calculate, to give us the wattage’s received upon Earth in the coming decades.
This approach can be replicated every so many centuries, by updating the vector information by observation; which in turn will show the trends in chord length changes; so that the Earth’s climate changes can be monitored as the approach of the next ice age takes place, as it surely will, as past geological evidence shows.”
Many people, even highly credentialed scientists, have difficulty absorbing and comprehending the key elements of Solar Chord Science. Indeed it seems that sometimes the highly credentialed have become so captured by long standing traditional ideas of astrophysics that it is very hard to shift the mind into new modes of thinking; into additional dimensions of mental challenge.
The difficulty comes about because it is necessary to contemplate SCS in three dimensions and in perpetually changing vector force terms. One can fairly easily think of force vectors in a two dimensional aspect, such as the two dimensions of the elliptic plane, but it becomes far more complex to think about the force vectors which exist when the third dimension (movement of the elliptic plane along the galactic path) is added as well. Then add the fourth dimension of time to introduce the fully dynamic force vector phenomena. It requires deep thought analysis, an openness of mind and a preparedness to challenge traditional precepts of some highly respected and credentialed entities of science (and a couple no longer quite as respected as they once were).
