【摘要】：日冕物质抛射(CME)是由太阳磁场驱动向行星际空间喷射等离子体物质和磁场的大尺度太阳爆发活动,是灾害性空间天气事件最主要的驱动源之一。朝着地球方向爆发的CME极易到达地球并造成灾害性空间天气,因此研究这类CME对于空间天气预报与太阳物理研究具有极为重要的意义。随着观测技术的发展,CME的观测及预报和研究工作取得了长足的进展。但由于常规观测手段与预报方法的局限,对朝着地球爆发的CME进行准确有效预报的目标至今仍未能实现。首先阐述CME与空间天气的关系,强调对CME预报研究的重要性;然后介绍预报研究中CME/ICME复杂的动力学过程,讨论这些过程对CME预报可能产生的影响;接着,回顾CME的常规观测手段,并讨论观测手段存在的不足;第4章,介绍CME主要的预报方法,同时讨论预报工作中存在的困难;第5章,讨论太阳雷达主动探测技术在日冕探测与CME预报研究中的可能应用前景;最后,总结CME预报研究现状,对预报研究工作中重要的问题进行综述,展望太阳雷达的未来应用。
[Abstract]:Coronal mass ejection (CME) is a large scale solar burst which is driven by the solar magnetic field to spray plasma and magnetic field into interplanetary space. It is one of the most important driving sources of severe space weather events. The CME exploding toward the earth is easy to reach the earth and cause disastrous space weather, so it is very important to study the CME in space weather prediction and the study of solar physics. With the development of observation technology, great progress has been made in the observation, prediction and research of CME. However, due to the limitation of conventional observation methods and prediction methods, the goal of accurate and effective prediction of CME exploding towards the earth has not been achieved yet. First, the relationship between CME and space weather is expounded, and the importance of studying CME prediction is emphasized. Then, the complex dynamic processes of CME-ICME in forecasting research are introduced, and the possible effects of these processes on CME prediction are discussed. Recalling the conventional observation means of the CME and discussing the shortcomings of the means of observation; chapter 4, introducing the main forecasting methods of the CME, as well as the difficulties in the forecasting process; and chapter 5, The possible application prospect of solar radar active detection technology in coronal detection and CME prediction is discussed. Finally, the research status of CME prediction is summarized, the important problems in forecasting research are summarized, and the future application of solar radar is prospected.
