Magnetic Storms Accompanied with Steady Magnetospheric Convection and Characteristics of the Ring Current during the Storms

  • 摘要: 参考活跃的磁层稳态对流标准,选取了2001—2017年12个伴随磁层稳态对流的磁暴,研究发现这些磁暴存在以下共性:有长达约10h的漫长主相;其SYM-H存在一个最小值的平台期,约持续3~10h;这些磁暴发生时,部分环电流持续位于昏侧,其持续时间和行星际磁场分量Bz的稳定南向驱动时间相等.此外,这些磁暴发生时,其平台期的环电流离子的寿命为2.4~5.5h,比一般的大磁暴事件中离子寿命长,且其寿命与平台期长短没有明显关系.伴随稳态对流的大磁暴发生时,环电流离子寿命长,环电流衰减慢,推测是稳态对流期间能量持续而稳定注入磁层导致的.
