摘要
本文介绍对日地系统扰动作多层次综合研究所取得的最新成果;分析了磁暴形态类型对行星际扰动结构,包括激波、高密度结构、强磁场结构、高速流等的响应特征;讨论了磁暴主相形成、延迟和消隐,及初相形成的条件;发现了行星际强磁场膨胀结构的动力学效应,及新的亚阿尔文波速流事例。
Presented in this paper are new results obtained through a comprehensive multi-region study of solar-terrestrial disturbances. The response of the morphological category of geomagnetic storms to interplanetary disturbance structures is analyzed, which includes the shock, the high density structure and the strong magnetic field structure, as well as the high-speed stream. The discussion involves interplanetary conditions for the formation, delay, and disappearance of strong main phase, and for the formation of initial phase. Observational evidences are found for the dynamic effect derived by an expanding interplanetary structure with strong magnetic field. Also found are new examples of the interplanetary sub-Alfvenic flow.
