大耀斑和电离层骚扰

Major Solar Flares and Ionospheric Disturbances

通过对负相电离层骚扰与大耀斑相关性的统计分析,发现不同纬度、季节耀斑引起的电离层骚扰出现概率是不同的,电离层骚扰与地磁暴,耀斑持续时间,耀斑所在的日面位置,太阳射电米波频谱Ⅱ和Ⅳ型暴发等存在着良好的相关关系。

This paper presents a ststistical analysis about the Correlation between the ionospheric disturbances of negative phase and the major flares.It shows that the probability of ionospheric distubances caused by flares is different at different latitudes and in different seasons.There are good correlations butween the ionospheric disturbances and the geomagnetic storms,the flare duration,the flare position on the sun—surfac and the Ⅱ and Ⅳ type bursts of solar radio meter—wave spectrum respectively.
