Abstract The study of the behavior of the ionosphere during disturbances is traditionally an important task. One of the authors in the GA 2018 paper found two groups of similar magnetic storms in 2013 and discovered a similarity in the behavior of the critical frequencies foF2 according to the data from the Sodanküla high-latitude station in the northern hemisphere, but this similarity was reduced to a negative disturbance, which is also characteristic of a large number of dissimilar magnetic storms. Nevertheless, it seemed interesting whether such a similarity could be inherent in the behavior of the total electron content TEC of the ionosphere. The study was carried out using data from three stations Juliusruh, Tromso, Longyearbyen near the 15° N meridian. It turned out that this similarity is observed in the behavior of foF2 and TEC, which is confirmed by high correlation coefficients between these parameters both during months and periods of disturbances.
