摘要：

Abstract: Results are presented from comparing an analytical study of the radial distribution of magnetohydrodynamic disturbances of magnetic field components in the body of a model solar wind magnetic cloud to data on a real cloud recorded on a spacecraft. An analytical–numerical solution for disturbances was found using a cylindrical coordinate system for a cloud represented by a force-free cylindrical tube with a helical magnetic field. The general idea of the radial distribution of the magnetic field components in the body of the magnetic cloud is consistent with the registered parameters of magnetic field disturbances on patrolling spacecraft, as is confirmed by an objective correlation analysis. Joint post-processing of the count results and real data enhances the consistency, testifying to the adequacy of the magnetohydrodynamic approach to analyzing oscillations in the model body of the magnetic cloud. © 2023, Allerton Press, Inc.
