| Abstract: | The contribution of global magnetospheric oscillations to magnetic disturbance during magnetospheric storms is studied. The
bases of magnetic data from the INTERMAGNET global network in combination with the interplanetary and intramagnetospheric
measurements of the magnetic field and plasma and the sets of the Kp, Dst, and AE indices are used for this purpose. The most favorable conditions in the solar wind and magnetosphere for generation of global
Pc5 have been revealed. The contribution of these oscillations to the variations in the magnetic disturbance level, characterized
by the AE index, has been estimated. The findings confirm that magnetospheric MHD oscillations participate in the processes of energy
income from the solar wind and energy dissipation in the magnetosphere. |
