摘要: In this paper, we describe a 3-dimensional MHD algorithm that provides global picture of the solar corona and inner heliosphere. For computational efficiency, split modeling region into two distinct parts: (1 radius, R s , to 30 ) heliosphere (30 1-5 AU). This combined model is driven solely by observed line-of-sight photospheric magnetic field thus can provide realistic for specific time periods interest. We validate results comparing them with variety observations, including white-light images in situ measurements, also point out main limitations our approaches toward resolving them. Ultimately, plan migrate research an operational tool, goal predicting geo-effective wind conditions up 4 days advance warning.
