Intermittency properties in the 3D heliosphere

Abstract

Apart from the earliest investigations on the fractal structure of magnetic field as observed in interplanetary space (Burlaga and Klein 1986), the starting point for the investigation of intermittency in the solar wind dates back to 1991, when Burlaga (1991a) started to look at the scaling of the bulk velocity fluctuations at 8.5AU using Voyager 2 data. This author found that anomalous scaling laws for structure functions could be recovered in the range 0:85≥r≥13:6h.
