Title: | A THERMODYNAMIC APPROACH TO THE MAGNETOSPHERIC COMPLEXITY: THE ROLE OF FLUCTUATIONS | Journal: | Space Science Reviews | Series/Report no.: | /122(2006) | Issue Date: | 2006 | Keywords: | Earth’s magnetosphere, thermodynamics |
Subject Classification: | 01. Atmosphere::01.03. Magnetosphere::01.03.03. Magnetospheric physics | Abstract: | Recent studies evidenced that the magnetotail dynamics looks like the one of an avalanching system. This fact has been related with a near criticality dynamics and modelled by singular diffusion and transport equations. Here, we discuss some features of the Earth’s magnetotail dynamics using a thermodynamic approach. In detailwediscuss the role played by fluctuations in singular diffusion and relaxation processes from a non-equilibrium thermodynamics point of view. Moreover, the emergence of non-Gaussian statistics is discussed in the framework of the thermodynamics of composite systems. |
