Effects of intermittency on interplanetary velocity and magnetic field fluctuations anisotropy

Intermittency is a well-established feature of interplanetary MHD fluctuati ons and, we show the effect of intermittency on the radial evolution of sol ar wind velocity and magnetic field fluctuations anisotropy. On one hand we confirm results obtained by previous investigations which showed that magn etic fluctuation anisotropy increases with distance and, on the other hand, we prove that much of this trend is due to intermittency. Once intermitten cy has been reduced, thanks to a technique based on wavelet transform for t he identification of the intermittent events, the radial trend vanishes. Si milar analysis performed on velocity fluctuations, showed that intermittenc y although altering the anisotropy, does not markedly change its radial tre nd.
