Simulation of atmospheric magnetic reconnections via a dynamic model of photosphere

We present a dynamic model of atmospheric magnetic field in which magnetic loop footpoints are advected by a velocity field computed using a simple n-body simulation and reproducing large spatial organization scales (e.g. mesogranulation). In this numerical simulation, the advection of passive magnetic elements triggers reconnection processes (oc- casionally multiple ones) forcing magnetic field reconfigurations and ensuing fluctuations of total magnetic energy. Our simple model reproduces a system with scale-free properties and provides probability distribution functions for emitted magnetic energies described by a power-law index 2:4.
