文摘 耀斑和日冕物质抛射(Solar flares and coronal Mass Ejections,CME)是产生灾害性空间天气的源扰动。Ⅱ型射电暴是CME驱动的激波在日冕和行星际空间中运动引起电磁波辐射的结果。以研究太阳物理和空间天气预警预报为背景,对Ⅱ型射电暴特别是甚低频Ⅱ型射电暴的频谱特征以及物理成因进行分析,认为甚低频Ⅱ型射电暴不但可以用于估计CME激波的运动速度、诊断日冕磁场等物理参数,还可以为空间天气预警预报方面提供参考。研究结果可以为空间甚低频射电观测设备的科学研究及应用方面提供有益的参考。
其他语种文摘 Solar flares and coronal mass ejections(CMEs)are the source disturbances of space weather. The type Ⅱ solar radio burst is the result of electromagnetic radiation caused by CME driven shock moving in corona and interplanetary space. Based on the study of solar physics and space weather forecast,the spectrum characteristics and physical causes of type Ⅱ radio burst, especially VLF type Ⅱ solar radio burst,are analyzed,it shows that VLF type Ⅱ solar radio burst can not only be used to estimate the velocity of CME shock,diagnose the coronal magnetic field,but also provide reference for space weather forecast. The research results can provide useful reference for the scientific research of space VLF radio observation equipment.
