Generation of acoustic-gravity waves in ionospheric HF heating experiments : simulating large-scale natural heat sources
… (e.g. prolonged heat wave events) in generating acoustic-gravity waves (AGWs) that might trigger widespread plasma turbulence in the ionospheric layer. The main hypothesis is that, the thermal gradients associated with the heat wave fronts could act as a source of powerful AGW capable of …

The Co-Volcanic Ionospheric Disturbances at Mt.Etna, Italy
… sounding. Due to the dispersive nature for radio waves, the ionosphere affects the GNSS signals as a function of its electron density. By this condition the total electron content (TEC) of the ionosphere can be estimated from GNSS data. TEC fluctuations can be related, from above, to space weather …

Study of Acoustic-Gravity Wave Spectra in the Atmosphere Using Mesosphere-Stratosphere- Troposphere Radar (Propagation, Universal Spectrum)
Current research indicates that acoustic-gravity waves can greatly influence the large-scale dynamics of the middle atmosphere. The morphology and structure of the atmospheric processes which cause this phenomenon can be better understood by the study of acoustic-gravity wave spectra. In order to …

Impacts of Anisotropy, Wave Heating, and Neutral Winds on High-Latitude Ionospheric Dynamics
… transverse ion acceleration by broadband ELF waves can give the upflowing ions sufficient energy for the mirror force to propel these ions to escape into the magnetosphere (ion outflow). In order to accurately examine the connection between upflow and outflow processes, a new two dimensional, …

Acoustic/Gravity Wave Phenomena in Wide-Field Imaging: From Data Analysis to a Modeling Framework for Observability in the Mlt Region and Beyond
<p>Acoustic waves, gravity waves, and larger-scale tidal and planetary waves are significant drivers of the atmosphere’s dynamics and of the local and global circulation that have direct and indirect impacts on our weather and climate. Their measurements and characterization are fundamental …
