“…Wavelet analysis has shown to be a very promising tool to analyze non-stationary hydro-climatic time series (Marcolini et al, 2017;Sang et al, 2018;Yeditha et al, 2021;Zolezzi et al, 2009). In the past decades, it has found application in a wide range of climatological studies based on oscillation indexes (Das et al, 2020;Fu et al, 2012;He et al, 2021;Jevrejeva et al, 2003;Massei et al, 2010;Ranzi et al, 2021) and has been applied to investigate streamflow variability in selected rivers worldwide (Agarwal et al, 2016;Labat, 2008;Labat, 2010;Labat et al, 2004;Massei et al, 2011;Nalley et al, 2012;Nalley et al, 2016;Nalley et al, 2019;Pérez Ciria et al, 2019;Rossi et al, 2009). Our work introduces an original wavelet transform approach to analyze the linkages between streamflow and the teleconnection patterns variability.…”
