Response of the high-latitude polar ionosphere to changes in the poynting vector orientation near the earth orbit relative to the geomagnetic moment orientation

For the first time, the research has been carried out into effect of the mutual orientation between Poynting vector P of the electromagnetic energy density in the solar wind and the vector M of the Earth's magnetic moment (with regard to its orbital and diurnal motions) on the geomagnetic activity. Measurements of solar wind parameters in the Earth's orbit (1963-2005) were used. The Pm component of the P vector along the M vector is shown to have a clear yearly variation with the extrema in November and May, and the UT variation with the extrema at ~6 and 18 UT. As shown by the analysis, the phases of the variations are determined only by geometric parameters and do not depend on the sector structure sign of the interplanetary magnetic field (IMP). The paper presents the experimental data on planetary and high-latitude geomagnetic activity that is the response to changes in P orientation relative to M. The power of the solar wind electromagnetic energy sources during strong geomagnetic disturbances is also estimated.
