Impacts of acoustic and gravity waves on the ionosphere

Frontiers in Astronomy and Space Sciences, 2022
The impact of regional-scale neutral atmospheric waves has been demonstrated to have profound effects on the ionosphere, but the circumstances under which they generate ionospheric disturbances and seed plasma instabilities are not well understood ...

Citizen Scientists Discover a New Auroral Form: Dunes Provide Insight Into the Upper Atmosphere

AGU Advances, 2020
Auroral forms are like fingerprints linking optical features to physical phenomena in the near‐Earth space. While discovering new forms is rare, recently, scientists reported of citizens' observations of STEVE, a pinkish optical manifestation of ...

Plasma Flows in Solar Filaments as Electromagnetically Driven Vortical Flows

Physics, 2021
Electromagnetic expulsion acts on a body suspended in a conducting fluid or plasma, which is subject to the influence of electric and magnetic fields. Physically, the effect is a magnetohydrodynamic analogue of the buoyancy (Archimedean) force, which is ...
