Using data from GNSS networks spanning the European-African sector, the occurrence of ionospheric irregularities induced during the geomagnetic storm of 6–8 March 2016 was studied. During the main phase of the event, strong and unusual mid latitude irregularities were detected at 50°-60°N on the night of March 6, 2016 before midnight and in the early hours of March 7, 2016. At the low latitudes, intense irregularities were observed to coincide with strong amplitude scintillation in the East African sector. The variation in the vertical total electron content had wave structure characteristics similar to that of large scale eastward travelling ionospheric disturbances. The irregularities and scintillation observed at low latitudes during this storm are ascribed to the prompt penetration electric field, which enhances the post-sunset eastward electric field. The intense irregularity structures that were observed at the same time at mid-latitudes are attributed to the northern auroral convection electric field, which extended from the polar cap equatorward to about 50°N during the main phase of the storm.

使用来自横跨欧洲-非洲地区的GNSS网络的数据，研究了2016年3月6日至8日发生的地磁风暴中电离层不规则现象的发生。在活动的主要阶段，2016年3月6日晚上午夜之前和2016年3月7日凌晨，在50°-60°N处检测到强烈且异常的中纬度不规则现象。在低纬度地区，强烈观察到不规则现象与东非地区强烈的幅度闪烁相吻合。垂直总电子含量的变化具有与大规模的东向电离层扰动相似的波结构特征。在这场暴风雨期间在低纬度地区观察到的不规则现象和闪烁归因于迅速穿透的电场，增强了日落后向东的电场。在中纬度同时观测到的强烈的不规则结构归因于北部的极光对流电场，它在风暴的主要阶段从极地赤道向约50°N延伸。
