“…The response of barometric formations at the midday regions of the Earth (namely, recess or filling of cyclones or strengthening or destruction of anticyclones) depends upon tbe sign of the magnetic field of the sunspot which is crossing the central meridian of the Sun (Nuzhdina and Barkova, 1983). Spontaneous phenomena of solar activity (solar flares) and crossings by the Earth of an IMF sector boundary are accompanied by changes of atmospheric pressure and cyclonic activity in some regions Mustel, 1972;Roberts and Olsen, 1973;Herman and Goldberg, 1978). A low-pressure region in the gulf of Alaska is more significant, when the IMF is directed away from the Sun, than towards (Wilcox, 1978).…”

Abstract.Connections between El Niño -Southern Oscillation (ENSO) phenomena and indices of solar activity and geomagnetic disturbance were investigated. Spectral analysis of the ENSO-data was carried out. Oscillations with periods of about 11-12, 5-6, 2-3 years were found. Correlative and cross-spectral analysis was carried out to estimate connections between ENSO data, and solar and geomagnetic indices. Functions of coherency and phase were calculated.

“…During an intense magnetic storm, the corpuscular energy flux could increase to Pc(max)1012=1014W which might be enough to use this energy as a trigger. According to ROBERTS and OLSON (1973) the energy of a typical rotating system of air U=5.3x1017J for the angular velocity w=6x105rad/s is comparable to the energy of a magnetic storm. Thus there appears to be enough power within the magnetosphere to cause such changes in vorticity of the lower atmosphere if the power can be directed and coupled effectively.…”

The correlations between geomagnetic, climatic, and meteorological phenomena were investigated with the object of demonstrating the function of the geomagnetic pole and changes of its position in controlling the climate and weather. A tentative model has been proposed to enable one to understand the causes of the generation of glacial and interglacial periods, as well as the causes which effect changes of climate (BUCHA, 1976a).The analyses of various types of geomagnetic and atmospheric manifestations have disclosed certain associations. The coincidence in the occurrence of increased spectral densities with regard to geomagnetic activity and the variations of atmospheric pressure over the geomagnetic pole shows the relation between their periodicities. The results imply that the changes in the intensity of corpuscular radiation, indicated by geomagnetic activity, affect the temperature and pressure patterns over the geomagnetic pole and polar region significantly, so that a pronounced modification of the general circulation may take place, as shown schematically (BUCHA, 1976b).As a result of investigating the relations between the variations of geomagnetic activity and meteorological factors a mechanism of solar-terrestrial relationships and a model of the changes of atmospheric circulation in the Northern Hemisphere are proposed; this provides a probable explanation of the causes of the fluctuation of the climate, of dry and cold periods and of differing vegetation conditions in various years in dependence on the intensity of geomagnetic activity (BUCHA, 1976(BUCHA, b, 1977.

“…The Discussion by Shapiro (1979) A recent discussion by Shapiro (1979) does not take proper account of the above considerations. In particular, by defining his own vorticity area index rather than analyzing the vorticity area index defined by Roberts and Olson (1973) he has attenuated out most of the apparent solar signal in the vorticity area index.…”
