Preliminary Numerical Study of the Outer Scale Size of Ionospheric Plasma Cloud Striations

Abstract

The one level, two-dimensional fluid equations modelling striation development in large F region ionospheric plasma clouds have been numerically solved, using an initial one-dimensional cloud geometry, for three different initial Pedersen conductivity gradient scale lengths L = 3, 6, 10 km. In the nonlinear regime evidence is presented for an outer scale size of well developed striations in a direction (y) perpendicular to the ExB drift (x) of the plasma cloud whose initial Pedersen conductivity varies only along the drift direction.
