Conductivity ratio effects on the drift and deformation of<i>F</i>region barium clouds coupled to the<i>E</i>region ionosphere

Abstract

The nonlinear motion of an F region barium release electrostatically coupled to the E region ionosphere is studied by numerical simulation. The effect of varying the ratio of the height-integrated Pedersen conductivity of the barium cloud (Σpb) to that of the background ionosphere (Σpi) and the formation of striations are discussed.
