日冕物质抛射检测研究进展

Research Progress on Detection of Coronal Mass Ejection

日冕物质抛射是一种规模巨大、程度剧烈的爆发现象,是影响地球的主要太阳爆发活动。由于这种爆发现象对地球环境造成严重干扰,因此,日冕物质抛射的探测对预报灾害性空间天气具有重要意义。为了更清楚地梳理目前存在的日冕物质抛射检测方法,对典型的方法进行分析总结。首先,介绍日冕物质抛射及其特征;然后,从基于手工方法和自动检测方法两方面对日冕物质抛射检测进行概述和分析;最后,讨论目前算法存在的一些问题,进而提出未来的研究方向。

A Coronal Mass Ejection(CME)is a large-scale,severely explosive phenomenon that is the main solar outburst affecting the Earth.As this kind of explosion will cause serious interference to the terrestrial environment,detecting CMEs is of great significance for forecasting severe space weather.In order to more clearly sort out the existing CME detection methods,this paper analyzes and summarizes the typical methods.Firstly,CMEs and their characteristics are introduced.Then,CMEs detection methods are summarized and analyzed from two aspects:manual methods and automatic methods.Finally,problems of the current algorithms are discussed and the future research direction is proposed.
