Abstract: | The coronal magnetic field configuration is important for understanding the energy storage and release processes that account
for flares and/or CMEs. Here we present a model which is based on the work for potential magnetic field problems that only
applies the condition at infinity with the boundary condition on the solar surface specified. We also discuss some recent
progress on general force-free field models. For some event analyses, we have employed MDI/SOHO longitudinal magnetogram insected
into the synoptic magnetogram to obtain whole boundary condition over the solar surface. Globally, the extrapolated global
magnetic field structures effectively demonstrate the case for the disk signature of the radio CMEs and the evolution of the
radio sources during the CME/flare processes. |
