We consider the problem of the effect of small plasma density variations on the propagation and
reflection of ELF (extremely-low-frequency) electromagnetic wave incident on the morning ionosphere
from above. Modifications of the electromagnetic wave field near the Earth surface and coefficient of
wave energy reflection from ionosphere caused by infrasonic wave are studied. The greatest
modifications of the field ...

In this paper, the internal structuring of Polarization Jet (PJ)/Subauroral Ion Drift (SAID) is
studied. It is shown that PJ/SAID consists of several Polarization Jet Strata (PJS) of electron density and
temperature. A new type of phenomena has been discovered called Stratified Subauroral Ion Drift (SSAID),
which is a PJ/SAID containing small-scale PJS. Internal small-scale structure of SSAIDs ...

В силу критической важности адаптации декаметровых загоризонтных радиолокационных станций к ионосферным условиям распространения радиоволн крайне актуальна организация оперативной диагностики ионосферы и автоматизация обработки её результатов. В работе показано, что существующее состояние такой обработки включает обязательное участие человека в стадиях выделения треков мод радиосигнала и идентификации треков мод сигнала. Поэтому делается постановка задач выделения и распознавания ...

The development of modulational instability involving dust acoustic perturbations in dusty ionospheric plasma and in dusty plasmas of meteor tails in Earth’s ionosphere was considered. The effect of collisions of electrons, ions, and dust grains with neutrals at different altitudes was estimated. It is shown that, in this case, the influence of collisions of electrons and ions ...

The broadband electrostatic turbulence generally observed in the high-latitude ionosphere is a superposition of nonlocal waves of ion-acoustic and ion-cyclotron types. In the presence of a shear of ion parallel velocity, ion-acoustic modes can be induced by an instability emerging due to an inhomogeneous distribution of energy density. This paper is devoted to the studies ...

Plasma instability caused by an inhomogeneous energy density distribution is considered. It is shown that this instability can lead to the excitation of electrostatic ion-cyclotron and oblique ion-acoustic waves, generated in the presence of an inhomogeneous transverse electric field and a shear in the parallel drift velocity of the plasma particles. The considered physical mechanisms ...

Satellite observations show that the electrostatic instability, which is expected to occur in most cases due to an inhomogeneous energy density caused by a strongly inhomogeneous transverse electric field (shear of plasma convection velocity), occasionally does not develop inside nonlinear plasma structures in the auroral ionosphere, even though the velocity shear is sufficient for its ...

U-shaped spectrograms observed by the DEMETER satellite in the equatorial region of the upper ionosphere are presented and explained for the first time. These spectra are characterized by the latitude-dependent upper cutoff frequency that increases with the latitude during nighttime. The observations suggest that this very low frequency wave phenomenon is closely connected with the anomalous increase in cold ...
