英文摘要	The three-dimensional global magnetohydrodynamic model (PPM-LR MHD) is employed to investigate the energy budget in the solar wind-magnetosphere system during the super magnetic storm on November 20, 2003, one of the biggest storms during the last decade with Dst similar to -500 nT. During this event, about 23% solar wind kinetic energy is transferred into the magnetosphere. The total energy input is estimated to be about 9.50x10(17) J, about 14 times of a moderate storm. The energy dissipation via the inner magnetosphere is less than the energy input with the coupling efficiency of similar to 63.3%. The energy dissipated via ring current injection is less than that via high-latitude ionosphere at the initial stage of the super storm. Furthermore, both the simulation results and the empirical results indicate that the ratio of ring current injection to the total energy output increases with the enhancement of the magnetospheric activity level. These are consistent with the statistical results we have got before. The empirical equations underestimate the solar wind kinetic energy, the energy input, and the energy dissipation via high-latitude ionosphere compared with the simulation results; however, the coupling efficiency of the high-latitude ionosphere (23.4%) is close to the simulation result (23.1%) during the entire storm time period.
