日冕物质抛射(CME)是太阳大气中频繁发生的最剧烈的爆发现象之一,也是灾害性空间天气事件最主要的驱动源,能在行星际空间乃至地球空间造成剧烈的扰动.行星际空间是CME爆发后影响地球空间环境的必经之路,在这过程中CME如何传播演化,对其最终的空间天气效应有着至关重要的影响.CME的行星际动力学过程涉及众多宏观与微观、线性与非线性等多时空尺度的问题,主要可以归纳为动量交换与输运、能量转化与输运以及磁通量转换与输运这三个方面.目前这些方面的认识和理解主要依赖于广角成像、射电频谱、多点局地等多种空间卫星探测手段和技术,随着探测技术的不断发展,人们对CME的行星际动力学过程必定会有更加深入甚至全新的了解.本文简要综述近年来在这方面的研究进展,以介绍国内外华人学者的工作为主,全面展现CME的行星际动力学过程.
CME is one of the most violent and frequent eruptions in the solar atmosphere and the most important driving source of disastrous space weather events, which can cause violent disturbance in interplanetary space and even in the earth’s space. Interplanetary space is CME after the outbreak of the impact of the Earth’s space environment, the only way CME in the process of how the spread of evolution, the final space weather effect has a crucial impact.MEME interplanetary dynamics process involves many macro and micro, linear And non-linear and many other issues in time and space, can be mainly summarized as three aspects of momentum exchange and transport, energy conversion and transport, and magnetic flux conversion and transport.At present, these aspects of understanding and understanding mainly rely on wide-angle imaging, Spectrum, multi-point local satellite spacecraft and other means and techniques of space exploration, with the continuous development of detection technology, people will have a more in-depth or even new understanding of the interplanetary dynamics of CME.In this paper, In this paper, we mainly introduce the work of Chinese scholars at home and abroad, and fully demonstrate the process of interplanetary dynamics of CME.
