EQUATORIAL HEATING AND HEMISPHERIC DECOUPLING EFFECTS ON INNER MAGNETOSPHERIC CORE PLASMA EVOLUTION

We have extended our previous semikinetic study of early stage plasmas phere refilling with perpendicular ion heating (Lin et al., 1992) by r emoving the restriction that the northern and southern boundaries are identical and incorporating a generalized transport description for th e electrons (e.g., Brown et al., 1991). This allows investigation of t he effects of electron heating and a more realistic calculation of ele ctric fields produced by ion and electron temperature anisotropies. Th e combination of perpendicular ion heating and
