We performed three-dimensional numerical simulations of the emergence of magnetic flux from the convectiove zone into the corona and its reconnection with a preexisting ambient coronal arcade field. Initially the flux tube in the convective zone is perturbed and becomes unstable to the Parker instability. The instability causes the rise and the expansion of the flux tube into the corona and the field comes into contact with the arcade field. When the upcoming field and the coronal arcade field generate current sheets between them, the reconnection occurs, causing profound changes in their connectivity. The local heating and the high-speed outflows caused by the reconnection can be seen in our simulations. We investigate how the changes in the angle of the arcade relative to the magnetic neutral line, lead to the different physical processes.
