等离子体片中的高速流自从被提出以来,由于其经常出现在磁层剧烈扰动期间而备受重视,然而有关其形成机制和在磁层扰动过程中的作用,特别是在整个磁层对流中的作用以及磁层亚暴触发过程中的作用并不十分清楚.本文简单回顾了高速流研究的历史,介绍了高速流的成因以及与极光的关联,探讨其与等离子体磁结构的异同及其与背景等离子体的相互作用,讨论了现有对高速流在磁层亚暴过程中作用的认识以及存在的问题,并提出了高速流研究中应当关注的几个关键科学问题.
The high velocity flow in plasma sheets has drawn much attention since it was proposed because of its frequent appearance during intense turbulence in the magnetosphere, however, with regard to its formation mechanism and its contribution to turbulence in the magnetosphere, especially throughout the magnetospheric convection And the role of sub-storm magnetosphere trigger process is not very clear.In this paper, a brief review of the history of high-speed flow research, introduced the cause of high-speed flow and the relationship with the Aurora, to explore its similarities and differences with the plasma magnetic structure and its The interaction between plasma and the background plasma is discussed. The current understanding of the role of high-velocity flow in the sub-stratospheric magnetosphere and its existing problems are discussed. Several key scientific issues that should be paid attention to in high velocity flow research are proposed.
