Modeling the dominance of the gradient drift or Kelvin–Helmholtz instability in sheared ionospheric E × B flows [PDF]

Physics of Plasmas, 2021
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
