М. V. Klimenko, and V. V. Klimenko Summary 1. In the given researches it is presented the new approach to modeling of the ionospheric effects of geomagnetic storm sequence: a) The use of AE- index with one-minute time resolution as an independent variable at modeling o f the temporal dependence o f potential difference through polar caps instead of 3-hour Kp- index; b) The realization of c) The assignment of field-aligned currents of the second region according to the theoretical ideas and experimental data available now; d) The account in model calculations the effects of solar flares took place during the considered period. 2. The new approach has allowed improving considerably the agreement o f the calculation results with experimental data. A c know ledgm en ts. Authors express the huge gratitude for use of the ionospheric observational data during the period on September 8-14, 2005 obtained from SPIDR. This study is supported by RFBR grant № 08-05-00274.
