Abstract

In the present work, the Solar Wind Speed (SWS) time series has been considered for study. Here, the intention of the authors is to investigate the presence of multifractality within the signal. Continuous wavelet transforms modulus maxima method has been employed in this purpose. The span of the time series of SWS, which is under consideration, is of 2492 days from 01/01/1997 to 28/10/2003. Finally, the Singularity spectrum is drawn to qualitatively evaluate the level of multifractality present within the SWS signal.
