Anisotropy in fast and slow solar wind fluctuations

Using 5 years of spacecraft data from near Earth orbit, we investigate the correlation anisotropy of solar wind magnetohydrodynamic-scale fluctuations and show that the nature of the anisotropy differs in fast (>500 km s -1) and slow (<400 km s-1) streams. In particular, fast streams a...
