AB: Recent solar observations have revealed that coronal jets are a more frequent phenomenon than previously believed. It is widely accepted that magnetic reconnection is the fundamental mechanism that gives rise to the jets. The improved spatial and temporal resolution of the STEREO observations in combination with stereoscopy yields new insights into the origins of coronal jets, and provides detailed data that can be used to test and refine models. We present the results of a 3D numerical simulation of our model for coronal jets. The simulations were performed with our state-of-art adaptive mesh MHD solver ARMS. The basic idea of the model is that a jet is due to the release of twist as a closed field region undergoes interchange reconnection with surrounding open field. We compare the structure and dynamics of the simulated jet with actual EUVI observations, focusing on how the reconfiguration of the 3D magnetic field explains observed properties of the jet. We also discuss possible signatures for STEREO of twisted structures within jets. Finally, we discuss the implications of our simulations for future stereoscopic observations with STEREO.
