N.A. Barkhatov et al. As a basic wavelet in numerical experiments Daubechies waves of fourth order is selected. Note that the observed spacing between together skeleton (excluding first and last, the occurrence of which is caused by edge effects) (see Fig. 1) to the characteristic time scale for the test frequency range is points. The wavelet scale factor of 4 to 15 (2-8 mHz), it averages ~ 25-30 minutes. This means that with such interval in this frequency range the entire vibrating system is changing. Therefore, the sample skeletons for latitude to calculate Dxn within a half-hour time window are formed. Consistent skeletons only those for which the value Dxn exceeded 70% was accepted. In Fig. 1 an example of calculating Dxn couples skeletons one of which always meets PSW or IMF are shows.

Skeletons, which were not included in the sample are marked «Inf». The abscissa is time in minutes, vertical axis - the value of large-scale wavelet coefficients corresponding to the frequency range of 2-8 mHz. A fragment of the data corresponds to the main phase of the storm 24.11.2001 1500 -1800 UT, Dst = -240 nT. 3. Improvement type of geoeffective Solar Flow with its spectral characteristics and the response time of the magnetosphere Application of technology to the analysis of skeletons of basic parameters of the interplanetary medium of the magnetosphere in the oscillations of the horizontal component of the geomagnetic field at different latitudes to come up to her indignation allowed us to estimate the response time. Experimental research the following pattern has shown. 1) Before storm time response of the magnetosphere in the perturbations of the geomagnetic field at coming up parameters of the Solar flow response in quick reaction in high latitudes and delayed reaction in sub-auroral zone is consist. Fig. 2 an example of registration of similar delayed skeletons is Shown. Indeed, the region of the polar cap and the auroral oval to the direct effects of disturbance leading edge of the solar flow is subject, while the sub­ auroral region emerging with intomagnitosphere source caused by the action o f the solar wind is registered. 2) The response time of the magnetosphere in the disturbances of the geomagnetic field at the initial phase of the storm at all latitudes considered equally poor was displayed. Fig. 3 an example of simultaneous registration of similar skeletons at different latitudes is shown. This is possible, if all stations the data being analyzed in this phase stay in the polar cap and the disturbances of the flow of the Solar Wind are registered. 3) The main phase of the storm under the action of the type of areas of interaction speed Solar Wind with slow flows (CIR), the reaction of the magnetosphere as a disturbances of the geomagnetic field at the disturbed parameters of the Solar flow by fast response at high latitudes and delayed in the subauroral zone is characterized. But under the influence of flow type as magnetic cloud with turbulent cover and/or with a shock wave the reaction time at all latitudes equally poor is considered. Difference as different geometries curving lines of the magnetosphere under the influence of different flows is due. Fig. 4 an example of registration of similar skeletons at different latitudes on the main phase of the storm under the influence of flow type magnetic cloud is shown. 38
