Abstract: | The 16 August 1999 EUV brightenings are numerically simulated by a third-order upwind compact scheme,basing on the TRACE observation.The present simulation call give a possible explanation to its formation and evolution.The numerical results show that the initial reconnection jets at around X-point are responsible for the occurrence of EUV brightening.The strong and superposed ejections caused by the first and second coalescence of magnetic islands are possibly related to the lifted material which initially appeared as absorption features and Later EUV-emitting structures respectively.The bi-directional reconnection jets may correspond to the lifted material that either continued to move upward along the apparently open field lines or fell down to the surface. |
