Scalings, Cascade and Intermittency in Solar Wind Turbulence

Abstract

Investigating in situ fluctuations in the interplanetary space, offers us a unique challenge to study scaling properties in a turbulent medium which cover a wide range of scales. This includes not only the inertial range, where turbulence can be described within a fluid-like approach, but also the high-frequency region, where a kinetic approach is required and turbulence strongly departs from a universal behavior. The dissipationless character of the solar wind plasma represents a further complexity in the usual complex nature of turbulence.
