Simulation results, based on a field-line-integrated, 2D, electrostatic model, are presented for the motion of a barium cloud injected transverse to the geomagnetic field in the ionosphere at high speeds. It is found that the gross evolution of injected plasma clouds depends sensitively on the initial conditions, as well as the nature of the background coupling. For a massive M sub O approx 10 kg, orbital V sub O approx 5 kmsec release in the F region 350-450 km, we find that plasma clouds can drift tens of kilometers across the magnetic field in tens of seconds after ionization.
