摘要

From two different models of exact axisymmetric analytical solutions of the MHD equations that govern a magnetized and rotating object, a new hybrid model is presented. The hybrid model input parameters are set from ULYSSES data of the solar wind for solar minimum. Using spacecraft data, the latitudinal dependences of density, velocity and magnetic field are constrained. This hybrid model is built having in mind the high flexibility of the parent models when applied in their proper domains. For the dead-zone, a three component solution for velocity and magnetic field is used, providing a wind geometry with non-radial streamlines and enabling the description of usual flaring of the field lines ob served in coronal holes, specially during the solar minimum (Tsinganos Sauty 1992, Sauty Tsinganos 1994). From the Alfven radius to one a.u. and further, the hybrid model keeps the latitudinal dependence as flexible as possible, this means to give up the latitudinal component of velocity and magnetic field and work with the remainders, turning the stream-lines into radial ones (Lima, Priest Tsinganos, 2001). This two component model provides the latitudinal versatility needed to deal with sharp variations of certain quantities near the equator, which are ob- served in ULYSSES data. The hybrid model allows describing the behaviour of all physical quantities with some agreement with the observational data.
