Annual Variations of the Galactic Cosmic Ray Intensity and Seasonal Distribution of the Cloudless Days and Cloudless Nights in Abastumani (41.75oN, 42.82oE; Georgia): (1) experimental study and (2) theoretical modeling
M. V. Alania, G. G. Didebulidze, R. Modzelewska +2
We study a possible relationships between seasonal distributions of the visually observed cloudless days (CD) and cloudless nights (CN) at Abastumani Astrophysical Observatory (41.…
27-day Variation of the Three Dimensional Solar Anisotropy of Galactic Cosmic Ray: 1965-2014
R. Modzelewska, M. V. Alania
The temporal evaluation of the 27-day variation of the three dimensional (3D) galactic cosmic ray (GCR) anisotropy has been studied for 1965-2014. 3D anisotropy vector was obtained…
Pecularities of cosmic ray modulation in the solar minimum 23/24
M. V. Alania, R. Modzelewska, A. Wawrzynczak
We study changes of the galactic cosmic ray (GCR) intensity for the ending period of the solar cycle 23 and the beginning of the solar cycle 24 using neutron monitors experimental…
Quasi-periodic changes of three dimensional solar anisotropy of galactic cosmic rays for 1965-2014
R. Modzelewska, M. V. Alania
We study features of the 3D anisotropy of galactic cosmic rays (GCR) for 1965-2014. We analyze the 27-day variations of the 2D GCR anisotropy in the ecliptic plane, and the north-s…
On the relationship of the 27-day variations of the solar wind velocity and galactic cosmic ray intensity in minimum epoch of solar activity
M. V. Alania, R. Modzelewska, A. Wawrzynczak
We study the relationship of the 27-day variation of the galactic cosmic ray intensity with similar changes of the solar wind velocity and the interplanetary magnetic field based o…
Modeling and experimental study of the 27-day variation of galactic cosmic-ray intensity for a solar-wind velocity depending on heliolongitude
M. V. Alania, R. Modzelewska, A. Wawrzynczak
We develop a three dimensional (3-D) model of the 27-day variation of galactic cosmic ray (GCR) intensity with a spatial variation of the solar wind velocity. A consistent, diverge…
