For the first time we present simulation results of the focusing effect of the ionospheric plasma density irregularities, namely, medium‐scale traveling ionospheric disturbances (MSTIDs), on solar radio emission by applying a ray tracing method to the Earth's ionosphere with MSTIDs. With this technique we investigate the focusing effect that manifests itself in the form of peculiar spectral disturbances in intensity with specific morphology, so‐called Spectral Caustics (SCs), occasionally…

Earlier developed interpretations of the effects of local focusing the high-frequency wave field on the ionospheric reflection paths of propagation are discussed. Consideration is based on the

lensing from small-scale travelling ionospheric disturbances observed using lofar

Observations made using the LOw Frequency ARray (LOFAR) between 10:15 and 11:48 UT on the 15th of September 2018 over a bandwidth of approximately 25-65 MHz contain discrete pseudo-periodic features



Traveling ionospheric disturbances as huge natural lenses: Solar radio emission focusing effect

We present an in‐depth study into spectral perturbations appearing in solar dynamic spectra and being manifestations of the focusing effect of low‐frequency solar emission by the Earth's ionosphere.

Ground and satellite observations of nighttime medium‐scale traveling ionospheric disturbance at midlatitude

[1] We have investigated a nighttime medium-scale traveling ionospheric disturbance (MSTID) observed by an airglow imager at Shigaraki (34.9°N, 25.4°MLAT), Japan, on 17 May 2001. The structure was

GPS observations of medium-scale traveling ionospheric disturbances over Europe

Abstract. Two-dimensional structures of medium-scale traveling ionospheric disturbances (MSTIDs) over Europe have been revealed, for the first time, by using maps of the total electron content (TEC)

Fibre structure of decametric type II radio bursts as a manifestation of emission propagation effects in a disturbed near-solar plasma

This paper addresses the fine structure of solar decametric type II radio bursts in the form of drifting narrowband fibres on the dynamic spectrum. Observations show that this structure appears in

Atmospheric gravity waves generated in the high‐latitude ionosphere: A review

A review of theoretical and observational results describing atmospheric gravity wave (AGW)/traveling ionospheric disturbance (TID) phenomena at high latitudes is presented. Some recent experimental

A theory of medium‐scale traveling ionospheric disturbances

Analysis of the excitation of atmospheric gravity waves leads to a hypothesis concerning the nature of medium-scale traveling ionospheric disturbances (TID's) and their relation to large-scale TID's.

Irregularities and irregular motions in the upper atmosphere have been detected and studied by a variety of techniques during recent years, but their proper interpretation has yet to be established.

Medium-scale traveling ionospheric disturbances affecting GPS measurements: Spatial and temporal analysis

[1] In this work we present a simple technique to estimate the medium-scale traveling ionospheric disturbances (MSTIDs) characteristics (such as occurrence, velocity, vertical propagation) with

Model of traveling ionospheric disturbances

A multiscale semi-empirical model of traveling ionospheric disturbances (TIDs) is developed. The model is based on the following assumptions: (1) TIDs are generated by acoustic-gravity waves (AGWs)
