Dynamics of the Cosmic Ray Current Behaviour During Large-Scale Solar Wind Disturbances
By using treatment results of world net neutron monitor data by the global survey method, the behaviour of cosmic ray current (anisotropy) during Forbush-effects for the 1965 to 1999 period is analyzed. Peculiarities of the current be-haviour before the shock wave arrival are investigated depending...

| Summary: | By using treatment results of world net neutron monitor data by the global survey method, the behaviour of cosmic ray current (anisotropy) during Forbush-effects for the 1965 to 1999 period is analyzed. Peculiarities of the current be-haviour before the shock wave arrival are investigated depending on the value of intensity decrease effect and heliocoordinates of disturbance sources on the Sun. Data of the Yakutsk underground complex of muon telescopes are also used in the analysis. Possibilities to predict the arrival of large-scale disturbances of in-terplanetary medium at the Earth by the behaviour of the observed cosmic ray anisotropy are discussed. 1. |
