Web24 feb. 2006 · Ions and electrons in a planet's ionosphere are produced by the photoionization of neutral species by solar extreme ultraviolet (EUV) and x-ray photons ( 4, 5 ). The ionizing solar flux and thus the ionosphere are variable on many time scales. Web14 mei 2024 · Studies have shown that in sheared E × B flows in an inhomogeneous ionospheric plasma, the gradient drift (GDI) or the Kelvin–Helmholtz (KHI) instability may grow. This work examines the conditions that cause one of these instabilities to dominate over the other using a novel model to study localized ionospheric instabilities.
