| Research Abstract |
The spontaneous fast reconnection model is extended to general three-dimensional situations, and the physical mechanism of fast reconnection evolution is studied by MHD simulations. The results are applied to flares and substorms, and the 3D structures of flaring loops and plasmoids are clarified. It is demonstrated that the plasmoid propagation in sheared fields is in good agreement with satellite observations; also, the fast reconnection evolution in low-beta plasmas in initially force-free current sheets is responsible for explosive flaring expansion and remarkable coronal heating.
