Langevin modeling of the magnetotail

It is widely recognized that the earth's magnetotail plays essential roles in determining global evolution of the magnetosphere. We model its dynamics from the viewpoint of the complex dynamical systems. Both statics and nonlinear time evolution of the multi-scale turbulence in the system are discussed, as they are superposed with external forcing terms representing lobe pressure and noise, as well as implications of our results to the observed characteristics of the magnetotail.

Spatial distribution of the magnetic field after avlanches of magnetic reconnection takes place.
