Abstract
Special method of correlation-skeleton processing of long period MHD disturbed components of the geomagnetic field is developed. To analyze space-time distribution for field components recorded along the meridian 210 at different stages of geomagnetic storms it is applied. This method on the base of post-processing of space-time wavelet analysis of disturbances was performed. The proposal of spectra calculation results in the form of wavelet skeleton pictures is shown. The method allows to find synchronization of oscillatory processes along the geomagnetic meridian and use it as indication of a global magnetic disturbance. Developed algorithm as a diagnostic tool state of the magnetosphere can also be used.
