The best way to study the changes in the climate "forcings" that impact the Earth's mean atmospheric temperature is to look at the first difference of the time series of the world-mean temperature, rather than the time series itself. Therefore, if the Perigean New/Full Moon cycles were to act as a forcing upon the Earth's atmospheric temperature, y...

Paper I showed that the epochs when the lunar line-of-apse points directly towards/away from the Sun, at times that were closely aligned with the Equinoxes and Solstices (i.e. seasonal boundaries), exhibited distinct periodicities at 28.75, 31.00, 88.50 (Gleissberg cycle), 148.25, and 208.00 (de Vries cycle) years. The caveat being that the alignme...

Lunar ephemeris data is used to find the times when the Perigee of the lunar orbit points directly toward or away from the Sun, at times when the Earth is located at one of its solstices or equinoxes, for the period from 1993 to 2528 A.D. The precision of these lunar alignments is expressed in the form of a lunar alignment index (ϕ). When a plot is...

The influence of solar retrograde motion on secular minima of solar activity, volcanic eruptions, climate changes, and other terrestrial processes is investigated. Most collected data suggest that secular minima of solar activity, powerful volcanic eruptions, significant climate changes, and catastrophic earthquakes occur around events of solar ret...

The international journal of Pattern Recognition in Physics was a good journal that might have become a renowned forum for important scientific papers. Its termination due to a straightforward conclusion on solar variability in relation to climate change is not only to be regretted as an unreasonable constraint on academic freedom but also excoriat...

This study identifies the strongest perigean spring tides that reoccur at roughly the same time in the seasonal calendar and shows how their repetition pattern, with respect to the tropical year, is closely synchronized with the 243 year transit cycle of Venus. It finds that whenever the pentagonal pattern for the inferior conjunctions of Venus and...

The Sun’s activity constantly varies in characteristic cyclic patterns. With new material and new analyses, we reinforce the old proposal that the driving forces are to be found in the planetary beat on the Sun and the Sun’s motions around the center of mass. This is a Special Issue published on Pattern Recognition in Physics where various aspects...

The idea that planetary effects may modulate, or even control solar variability is old; having been investigated by Rudolf Wolf from 1859 until his death in 1893. Many further efforts to measure and explain the possible mechanisms for planetary solar effects have been made by researchers at frequent intervals through the years. Despite this it has...

In a collection of research papers devoted to the problem of solar variability and its origin in plan-etary beat, it is demonstrated that the forcing function originates from gravitational and inertial effects on the Sun from the planets and their satellites. This conclusion is shared by nineteen co-authors.
Article
Full-text available
A Venus-Earth-Jupiter spin-orbit coupling model is constructed from a combination of the Venus-Earth-Jupiter tidal-torquing model and the gear effect. The new model produces net tangential torques that act upon the outer convective layers of the Sun with periodicities that match many of the long-term cycles that are found in the 10Be and 14C proxy...

Wilson and Sidorenkov find that there are four extended pressure features in the summer (DJF) mean sea-level pressure (MSLP) anomaly maps that are centred between 30 and 50°S and separated from each other by approximately 90° in longitude. In addition, they show that, over the period from 1947 to 1994, these patterns drift westward in longitude at...

The longitudinal shift-and-add method is used to show that there are N=4 standing wave-like patterns in the summer (DJF) mean sea level pressure (MSLP) and sea-surface temperature (SST) anomaly maps of the Southern Hemisphere between 1947 and 1994. The patterns in the MSLP anomaly maps circumnavigate the Earth in 36, 18, and 9 years. This indicates...

This study looks for evidence of a correlation between long-term changes in the lunar tidal forces and the inter- annual to decadal variability of the peak latitude anomaly of the summer (DJF) subtropical high pressure ridge over Eastern Australia (LSA) between 1860 and 2010. A simple "resonance" model is proposed that assumes that if lunar tides p...
Conference Paper
Full-text available
We find that a number of significant climate indicators are synchronized with changes in the decadal variations in the Earth’s length of day (LOD). These indicators include: variations in the rate of the westward drift of the geomagnetic eccentric dipole; incremental variations in the masses of the Antarctic and Greenland ice sheets; anomalies of t...

Catastrophic multi-year failure of the Indian monsoon has caused at least eight mega-famines in India over the last 1100 years. Historical data shows that seven out of the eight mega-famines have either started within +/- one year of the year of greatest asymmetry in the Sun's motion about the Solar System's centre-of-mass, or 11 years +/- one year...

We present evidence to show that changes in the Sun's equatorial rotation rate are synchronized with changes in its orbital motion about the barycentre of the Solar System. We propose that this synchronization is indicative of a spin-orbit coupling mechanism operating between the Jovian planets and the Sun. However, we are unable to suggest a plaus...

A parameter that is indicative of the peak planetar y tidal forces acting upon the Sun i.e. changes in the alignment of Jupiter, at the time of inferior and sconjunctions of Venus and Earth, naturally exhibits characteristics that either mimic or repli cate five of the main properties of the solar cycle . These properties include: the Schwabe cycle...

Evidence is presented to show that the phases of two of the Earth's major climate systems, the North Atlantic Oscillation (NAO) and the Pacific Decadal Oscillation (PDO), are related to changes in the Earth's rotation rate. We find that the winter NAO index depends upon the time rate of change of the Earth's length of day (LOD). In addition, we fin...

We find that there is substantial correlation between the dominant periodicities that are seen in the long-term solar activity cycle and the periodicities in a carrier suppressed amplitude modulated signal with frequencies related to the Sun's Barycentric motion. Both quantities show periodicities at the de Vries (210 years), Gleissberg (90 years),...

The Lamers (1981) data sample of mass loss rates and stellar parameters for OB stars is presently supplemented by Of star data from the Garmany et al. (1981) sample to derive an empirical expression that relates mass loss rate to stellar luminosity, radius, and mass. The ratio of the momentum carried away by the stellar wind to the momentum of the...

New near-infrared spectrophotometric observations show that the relative strengths of the sulfur forbidden emission lines S III 9069, 9532 A with respect to H-alpha constitute a powerful diagnostic to distinguish between shock and photoionization mechanisms in Liners (Low Ionization Emission-line Regions). These observations strongly support the id...

New near-infrared spectrophotometric observations show that the relative strengths of the sulphur forbidden emission lines SIII 9069, 9532 A with respect to H-alpha, constitute a powerful diagnostic to distinguish between shock and photoionization mechanisms in LINERs. These observations strongly support the idea, already favored on the basis of ab...

Empirical calibrations based on prior studies of Galactic OB Stars are used to determine the integrated stellar wind mechanical luminosity (Lw) and the integrated Lyman continuum photon luminosity (S-star) for 10 OB clusters in the LMC. These values of Lw and S-star, together with narrow band H-alpha surface photometry of an overlapping sample of 1...

In connection with a number of general radio surveys of clusters of galaxies conducted during the last 18 years, it has been attempted to answer a number of questions regarding radio galaxies. The present investigation is concerned with a statistical analysis which provides information concerning these questions. It is believed that the results are...

The discovery of powerful X-ray emission with an apparently thermal spectrum from a considerable number of clusters has been attributed to a hot intracluster gas. Such a gas surrounding a radio galaxy may conceivably retard the expansion or diffusion of the relativistic electrons. This would eventually result in a steepening of the radio spectrum c...

From a wide variety of observational data, it is concluded that N70, a giant shell H II region in the LMC, is a mass-loss bubble confined by the ram pressure of a massive, collapsing H I cloud, along the lines of the model described by Dopita (1981). From this model, the age, the parameters of the H II region and the H I cloud, the mass-loss rate,...

Results of coordinated program of observations in the X-ray, UV, optical and radio regions of the dM5e flare star Proxima Centauri are presented. Simultaneous observations of the star were obtained on March 6 and March 7, 1979, by the Einstein Observatory IPC, the IUE SWP and LWR cameras at low dispersion, three ground-based optical telescopes in A...
Article
The problem of the interaction of a strong stellar wind with a massive collapsing neutral hydrogen cloud has been considered and a new class of steady flow solutions found. The detailed comparison of these models with one filamentary shell, N70 in the LMC, shows that they successfully explain all the observed properties of the HII region and enable...

The main goal of this project is to show that it is possible to connect short- term weather phenomenon that are being driven by the luni-solar tides to much longer term variations in climate that are seen on centennial to millennial time scales. The short-term phenomenon include weather patterns that vary on time scales of ~ 4 - 9 days, as well as multi-annual ENSO-like weather patterns that show variations on time scales of 4.5 years. We hope to show that times where the lunar line-of-apse points directly towards or away from the Sun near times where the Earth is located at one of seasonal boundaries (i.e. it's solstices and equinoxes) cause a ~ 4.5 year oscillation in the Earth's climate. The ~ 4.5 year cycle arises from changes in the Earth's LOD that are produced by the interaction of the tropical and anomalistic lunar months and the solar driven semi-annual variation in the Earth's LOD. The slow variation of the interaction between the lunar alignment patterns and the Earth's seasons over time have long-term cycles that closely match those seen in the Earth's climate system and those that are seen in the overall level of magnetic activity of the Sun's. We propose a Luni-Solar Climate Model to explain why there are matching frequencies seen in the proxy data for Earth's climate, the variations in the magnitude of the solar magnetic cycle and the long-term lunar alignment cycles.
