dc.description.abstractThe coupled, time-dependent continuity, momentum and energy equations for four charged species (H+, He+, O+ and electrons) moving through a stationary upper neutral atmosphere (composed of O2, N2, O, He, H) were solved along open geomagnetic field lines using a modified version of the /5/ model. The thermospheric densities and temperatures, obtained from the MSIS-86 model /7/, were used to calculate neutral-ion sources, sinks, and collision frequencies. The various cross sections and conductivities employed by the /5/ model were also updated. The paper presents the first time-dependent solutions for the He+ component of the polar wind. Special attention is paid to the solar cycle variation of the ion upflows.en_US
