The Effect of the Relative Orientation between the Coronal Field and New Emerging Flux. I. Global Properties

摘要: The emergence of magnetic flux from the convection zone into corona is an important process for dynamical evolution coronal field. In this paper we extend our previous numerical investigations, by looking at interaction as initially twisted tube emerges a plane-parallel, Significant differences are found in appearance and depending on relative orientation between rising system any preexisting When systems nearly antiparallel, experiments show substantial reconnection demonstrate clear signatures high-temperature plasma located high-velocity outflow regions extending region. However, cases that have more parallel very limited none associated features. Despite different amount two systems, it emerging still connected to original reaches same height function time. As compensation loss flux, difference extent loop direction perpendicular main axis initial tube. Increasing amounts decrease volume, which confines remaining flux.
