The impact of regional-scale neutral atmospheric waves has been demonstrated to have profound effects on the ionosphere, but circumstances under which they generate ionospheric disturbances and seed plasma instabilities are not well understood. Neutral vary from infrasonic <20 Hz gravity with periods order 10 min, for simplicity, hereafter combined common term Acoustic Gravity Waves (AGW...

The effects of large winds on the low-latitude E region ionosphere and the equatorial electrojet in particular are analyzed theoretically, computationally, and experimentally. The principles that govern the relationship between electric fields, currents, and winds in steady flows in the ionosphere are reviewed formally. A three-dimensional numerical model of low latitude ionospheric electrostat...

This is a general review of the existing climatological models of ionospheric radio scintillation for high and equatorial latitudes. Trans-ionospheric communication of radio waves from transmitter to user is affected by the ionosphere which is highly variable and dynamic in both time and space. Scintillation is the term given to irregular amplitude and phase fluctuations of the received signals...

The ionosphere has practical importance in GPS (Global Positioning System) applications because it influences transionospheric radio wave propagation. Among various phenomena in the ionosphere, ionospheric scintillation is characterized by rapid fluctuation and fading of the received signal intensity due to electron density irregularity inside the ionosphere. Deep signal fading caused by scinti...

[1] A growing multispectral database plus recent Galileo descent measurements are being used to construct a self-consistent picture of the Jupiter thermosphere/ionosphere system. The proper characterization of Jupiter’s upper atmosphere, embedded ionosphere, and auroral features requires the examination of underlying processes, including the feedbacks of energetics, neutral-ion dynamics, compos...

[1] Polarization electric fields created by the Eand Fregion dynamos cause the uplift of F-region plasma. The subsequent redistribution of that plasma along the magnetic field lines creates the equatorial ionospheric anomaly (EIA). Observations of the post-sunset EIA made by the IMAGE and TIMED satellites are compared here with CHAMP, Ørsted and SAC-C observations of the noontime equatorial ele...
