| 英文摘要 | Geomagnetic storms are mainly resulted from the ring current, the decay rate of which is one of the key parameters for estimating energy budget of the magnetosphere and for storm prediction. Two new criterions are proposed in this paper for evaluating the decay rate: (1) the E-criterion: the total energy balance for a storm event, or balance between the integrated energy input and output during whole course of the event; (2) the L-criterion: the total energy balance for a long interval, or balance between the integrated energy input and output for a long interval. Several models of decay rate are examined by using 44 selected storms during 1998 similar to 2003 and an 11-year-long continuous record for the 23rd solar cycle (1998 similar to 2008). The results show that the models PA1978 and XD2010 show fairly well energy balance for all the storm events, satisfying the E-criterion. In addition, the two models fairly well satisfy the L-criterion, exhibiting enhanced energy dissipation during major storm events and long-term energy balance. |
