Abstract
The intensity of cosmic rays in a magnetic cloud is calculated. It is found that the duration of the Forbush decrease recovery is determined by the magnetic cloud orientation and the reduction in the magnetic field inside the magnetic cloud as it expands. The formation of the Forbush decrease is described in terms of the contributions from different sources of particles.
