Abstract
We presented the results of a comparison of the analytical study of the features of the radial distribution of MHD disturbances of the magnetic field components in the body of a model solar wind magnetic cloud with data on a real cloud recorded by a spacecraft. The analytical-numerical solution for perturbations is performed in a cylindrical coordinate system for a cloud represented by a force-free cylindrical tube with a helical magnetic field. The obtained general idea of the radial distribution of the magnetic field components in the MC body is consistent with the registered parameters of the magnetic field disturbances on the patrol spacecraft and is confirmed by an objective correlation analysis. Joint post-processing of the counting results and real data compared with them enhances the consistency, which indicates the adequacy of the applied MHD approach to the analysis of oscillations in the model body of the magnetic cloud.
