    The results of spectral analysis of series of observations of the equatorial and polar diameters, as well as of series of satellite observations of the S sub O variations during 1975 to 1987 presented in papers by Laclare (1987), Delache (1988) and Delache et al. (1988) confirm with confidence the presence of an 11-year modulation in the Sun's radiation and diameter, and consequently, in the effective temperature of the photosphere. The same conclusion has been drawn with regard to the 1000th and 320th daily periodicities. In combination with the results of other research, several obvious conclusions can be drawn from the data presented. The 76-year variation in the period from 1967 to 1987 is not revealed in the data of observations; the data of the middle series will doubtless be made more precise after the facsimile from the initial information is obtained. The basic and comparable contributions to the radius variability yield the 11- and 22-year variations. The presence can easily be seen of harmonics with periods of 2 and 4 years; the 4-year period is revealed up to 1979 only, and the 2-year one, after 1980 only. This is possibly due to the combined contribution of the 11- and 22-year variations (to be more precise, 10.8 and 21.2 years) forming a certain mean 16-year periodicity. In this case, the 4- and 2-year variations can be regarded as the 4th and 8th harmonics of such a mean variation. Measurements of the horizontal diameter made at Greenwich Observatory have not lost their significance for the analysis of phenomena on the Sun, since they contain data having precision characteristics conforming to the level of the latest ground-based diameter measurements

    Some Results from Studies on Relationships Between the Optical-meteorological Parameters and Solar Activity. Part 2: Development of the Problem of Solar Forcing

    A set of complex spectral, actinometric and meteorological data obtained in the periods of heightened solar activity (1981 and 1988) has been considered in order to reveal the atmospheric component affected by solar emissions in the troposphere and lower stratosphere. For the first time, it has been found out that water vapor molecules can be transformed, under the impact of corpuscular and microwave solar emissions, from the free state to the bound one (association into clusters), and vice versa. The transition of water vapor molecules into the bound state results in a decrease of spectral optical thickness in the visible, near IR and IR spectral regions, and an appearance and deepening of the cluster absorption bands at wavelengths 330 to 340, 365, 380 to 390, and 480 nm

    Scaling violation in the fragmentation region of inclusive nucleon spektrum

    Spectra of cosmic ray showers associated with hadrons of various energies from 5 to 80 TeV were investigated. Results could be interpreted as scaling violation in the fragmentation region of secondary particles generated in inelastic interactions of primary protons at the energy above 30 TeV

    Primary gamma-rays with E gamma or = to 10(15) eV: Evidence for ultrahigh energy particle acceleration in galactic sources

    The recently observed primary ultra high energy gamma-rays (UHEGR) testify to the cosmic ray (CR) acceleration in the Galaxy. The available data may be interpreted as gamma-ray production due to photomeson production in CR sources

    Solar cosmic ray bursts and solar neutrino fluxes

    The neutrino flux detected in the C1-Ar experiment seems to respond to the powerful solar cosmic ray bursts. The ground-based detectors, the balloons and the satellites detect about 50% of the bursts of soalr cosmic ray generated on the Sun's visible side. As a rule, such bursts originate from the Western side of the visible solar disk. Since the solar cosmic ray bursts are in opposite phase withthe 11-year galactic cosmic ray cycle which also seems to be reflected by neutrino experiment. The neutrino generation in the bursts will flatten the possible 11-year behavior of the AR-37 production rate, Q, in the Cl-Ar experiment. The detection of solar-flare-generated gamma-quanta with energies above tens of Mev is indicative of the generation of high-energy particles which in turn may produce neutrinos. Thus, the increased Q during the runs, when the flare-generated high energy gamma-quanta have been registered, may be regarded as additional evidence for neutrino geneation in the solar flare processes

    Impact of solar activity on structure components of the Earth. I. Meteorological conditions

    The mountain observations (Northern Caucasus) carried out during solar activity (SA) cycles 21, 22, and 23 testify to substantial SA impacts on radiative, optical, microphysical and meteorological parameters of the troposphere. Due to disturbances imposed on natural variations of meteorological parameters and changes of the microphysical state of the ensemble of water vapor molecules, distinct disturbances of the synoptic period lengths have been observed. Apparent responses of the atmosphere to activated processes on the Sun in October 1989, April 2002 and October 2003 confirm the existence of contributions to atmospheric perturbations of flare fluxes of protons (SCR) and fluxes of recently identified spiral-vortex radiation (SVR) outgoing via photospheric magnetic structures of various scales. With the 20 October 1989 event as an example, contributions of the flare flux of protons and the spiral-vortex radiation to dynamic processes in the lower troposphere have been illustrated. A conclusion has been drawn about similar level but different directions of their impacts on the degree of water vapour molecules association in the atmosphere. Destructive forcings of the focused SVR and its various manifestations on the dark side of the Earth (and, apparently, of the Moon) have been mentioned

    Twenty-five years high-mountainous researches on solar-weather effects have given a number of direct proofs of the occurrence of weather meteoelements abnormal responses (in scale hours-days-week) on the passage in the central area of the solar disk by separate large sunspots and powerful groups of spots. The brightest shows were marked by us in October 1981 and in the last decade of October 2003. Certainly, the most grandiose effect was registered in March 1920 at the Calama station of the Smithonian Astrophysical Observatory (ΔS0 ≈ 5%). The analysis of the data set unambiguously has specified the presence of a special kind of radiation in the solar emissions—spirally vortical radiation (SVR), having a forcible pulse and powerful angular moment. In our opinion spirally vortical radiation is generated in the nu cleu s of the Su n with a speed of 104 quantums/s and leaves the photosphere through magnetic structures with a speed ∼ 8–9 · 103 km/s. In the paper we discuss the effects of the direct interaction of spirally vortical radiation with different kinds of terrestrial environments, including the biosphere. It is supposed that SVR in the Universe can play a role of dark energy, as it is radiated by each star and has a pulse
