Abstract: The effect of high-speed recurrent solar wind streams from coronal holes on the intensity of the galactic cosmic rays has been investigated. The distribution of galactic cosmic rays for various solar cycle phases was considered on the basis of data of neutron monitor world network. In the framework of inhomogeneous model which includes homogeneous background and regions of high-speed streams, the transport equation solution has been obtained and the effect of high-speed streams on the galactic cosmic ray spatial distribution has been evaluated. It is shown that theoretical calculations is confirmed with experimental results that have been obtained for 2000—2014 years if to apply assumptions regarding the mean free path of cosmic rays in the corresponding period of high-speed streams. |
