“…Both analyses are based on a series of smoothed auto-and crosswavelet power spectra (Grinsted, Moore, & Jevrejeva, 2004;Kumar & Foufoula-Georgiou, 1997;Torrence & Compo, 1998), which require the calculation of wavelet coefficients at different scales and locations for each variable. We only briefly introduce the equations related to the bivariate wavelet coherency and MWC in this section, and readers can refer to previous studies for the details (Carey et al, 2013;Das & Mohanty, 2008;Graf et al, 2014;Grinsted et al, 2004;Hu & Si, 2016;Mullon, Chang, Yang, & Weiss, 2013;Perez-Valdivia, Sauchyn, & Vanstone, 2012;Rashid, Beecham, & Chowdhury, 2015;Schaefli, Maraun, & Holschneider, 2007;Si, 2008;Torrence & Webster, 1999).…”
