Annotation

In experimental investigations of the ionospheric dynamic processes by use of various sounding methods, one of the main conceptual problems is an adequate interpretation of the temporal variations of the detected signal. In particular, since in most cases the signal reflects fluctuations in the electron concentration, which are associated with the dynamics of ionospheric disturbances (such as the travelling ionospheric disturbances, TIDs), the source of the generation of such TIDs must be determined, and the role of that source can play the internal gravity waves (IGWs) [1,2] and acoustic gravitational waves (AGWs) in the neutral component, which, in turn, are excited by impulse type sources of different natures (see also [9]). For example, theoretical studies [10-12] first predicted phenomena such as the generation of two-dimensional IGWs solitons in the regions of sharp gradients of the main ionospheric parameters (on the fronts of solar terminator and solar eclipse spot). These received qualitative confirmation in the experiments on ionospheric sounding. However, it is well known that there are no direct methods for the measurement of neutral component dynamic parameters, i.e. IGW characteristics, on ionospheric heights. Thus, the calculation of quantitative dynamic IGW characteristics from the measured data is definitely still relevant at present.
