It was established that TIDs, which were recorded at the heights of the maximum of the F2 region of the ionosphere, had amplitudes of ~10% and periods of ~60–180 min. Such TIDs are large-scale ones that are generated in auroral zones during magnetic storms. These TIDs were confidently identified not only manually, but also using a neural network that was improved to fulfill the tasks of this research. Successful testing of the network's functioning indicates the effectiveness of its algorithms and the possibility of using them for automatic analysis of observation data.
