We have developed a 2D semi-empirical MHD model of the solar corona and solar wind. The model uses empirically derived electron density profiles from white light coronagraph data measured by SOHO and empirically derived model of the magnetic field which is fit to observed streamer topologies which also come from white light coronagraph data. The model requires an estimate of solar wind velocity as a function of latitude at 1 AU and radial component of the magnetic field at 1 AU for which we use Ulysses plasma and magnetic field data results. The model makes estimates as functions of radial distance and latitude of various fluid parameters such as flow velocity V, effective temperature Teff and effective heat flux qeff which are derived from conservation equations of mass, momentum and energy in the rotating frame of the Sun. The term effective indicates possible wave contributions. The model is a steady state calculation that assumes azimuthal symmetry. The magnetic field model shows that the large scale surface magnetic field is dominated by an octupole term. Initial attempts assumed the presence of a single current sheet which appears to be topologically incompatible with an internal field dominated by an octupole term. These earlier attempts had problems modeling the plasma and magnetic field near the Sun close to the equatorial plane. Therefore, for this study we have investigated the possible presence of multiple current sheets near the Sun for which initial results indicate that most of the problems with the magnetic field are corrected. For this paper we will present the results of this latest study.
