The 27-Day Variations of the Cosmic Ray Diurnal Variations

27-day Variations of the Galactic Cosmic Ray Intensity and Anisotropy∗

We study the relationships of the 27-day variations of the galactic cosmic ray (GCR) intensity and anisotropy with the 27-day variations of the solar wind (SW) velocity, Wolf number (Rz) and interplanetary magnetic field (IMF) strength for different positive (A > 0) and negative (A < 0) polarity periods of the solar magnetic cycles based on the experimental data. We found that the long-lived ac...

The secular variations of cosmic ray cutoff rigidities ,

Vertical rigidities of geomagnetic cutoff are obtained for world neutron monitor network with annual resolution for the period of 1950-2020 by the method of trajectory calculations with the model International Geomagnetic Reference Field. Results of the computations show the total decrease of the cut off rigidities in the majority points which is caused by a decrease of the total geomagnetic fi...

Confinement–driven Spatial Variations in the Cosmic Ray Flux

Low–energy cosmic rays (CRs) are confined by self–generated MHD waves in the mostly neutral ISM. We show that the CR transport equation can be expressed as a continuity equation for the CR number density involving an effective convection velocity. Assuming balance between wave growth and ion–neutral damping, this equation gives a steady–state condition ncr ∝ n 1/2 i up to a critical density for...
