AB: We continue our three-fluid (electrons, ions, and neutrals) approach to describing the dynamic processes of solar wind-magnetosphere-ionosphere/thermosphere coupling based on the three-fluid generalized Ohm's law, the plasma momentum equation, and the neutral momentum equation, as well as the Maxwell equations, which include the electromagnetic coupling among the charged species and collisions among the three species. We study the responses of the ionosphere to a change in the magnetospheric convection assuming a one- dimensional stratified ionosphere. The driver is added only at the top boundary of the ionosphere. The whole system starts moving in a self-consistent manner. The system is not coupled via the electric field and/or field- aligned currents vertically as conventional models are. We examine the time dependence and height dependence of the plasma flow, the current, the electric field, and the neutral wind velocity.
