摘要：

Impulsive dynamical processes in the solar corona, such as the flaring of magnetic loops, can be modeled by compressible one-dimensional magnetohydrodynamic (MHD) equations with a forcing that mimics the erratic motion of the magnetic footpoints. Two different kinds of dissipative events are observed in such a model, the study of which sustains the image of an efficient heating by a swarm of small events.
