Given the recent observational results of interchange reconnection processes in the solar corona and theoretical development of the S-Web model for the slow solar wind, we present further analysis of the 3D MHD simulation of interchange reconnection by Edmondson et al. (2009). Specifically, we will analyze the observable properties of the dynamic streamer belt jump that corresponds to previously closed streamer belt flux opening up via interchange reconnection. We quantify the system's kinetic energy and open flux evolution in time and show that the material released from the reconnection region outflow is qualitatively similar to the transient slow solar wind features known as "streamer blobs". Our simulation results imply that the commonly accepted interpretation of streamer blobs as small-scale magnetic flux-ropes may not be universally applicable. Additionally, we examine the synthetic emission from the density evolution above the surface and show the correspondence between coronal "dimming" and the opening up of previously closed flux. We will discuss future improvements to the MHD simulations that include a solar wind outflow and more rigorous comparisons to observations.
