Power laws in the Magnetosphere - Why are they so interesting? A data analyst's perspective

There is a growing body of work that shows scale free behaviour in a wide range of phenomena in the Magnetosphere-Ionosphere system. These observations include the AE indices, magnetic fields, electric fields, auroral brightenings, convection flows and magnetic structures associated with reconnection. They have been analysed using a variety of techniques including spectral analysis, threshold crossings and structure function analysis. This seminar presents some analysis of convection velocities measured by the SuperDARN radar which show scale free complex behaviour. These results will be discussed in the wider context along with some of the implications of scale free behaviour in the Magnetosphere. These implications affect both the way we view the system and the framework within which we should view observations.
