WebJul 15, 2012 · Scaling index α derived from the slope of logarithmic diagrams (LD) constructed by the discrete wavelet transform of data can be estimated as α = 2.2 ± 0.3, which is close to α estimate earlier reported for scales 1–30 km by electric field observations of the Dynamics Explorer 2 satellite. Web(1) In this paper we investigate how the parameters of the ionosphere and the low-altitude magnetosphere mediate the formation and spatiotemporal properties of small-scale, intense electromagnetic structures commonly observed by low-altitude satellites in the auroral and subauroral magnetosphere. The study is based on numerical modeling of a time-evolving, …

WebDec 5, 2008 · Another possibility is raised by Chust et al. [2005] is that small-scale Alfvén waves observed by Galileo may be evidence of a filamentation processes within the torus. Filamentation converts long Alfvénic pulses into small-scale waves which are reflected back to Io and also transmitted Jupiterward. how does the stranger endWebThis paper presents a comprehensive review of dispersive Alfvén waves in space and laboratory plasmas.
