Cross-wavelet transform of monthly AO & WPSH and monthly rainfall at Hengshan (a, f), Yan’an (b, g), Hancheng (c, h), Qindu (d, i), and Zhenba (e, j) stations as well as the mappings of CI (k) and PCI (l) in three periods.
In subfigures (a)-(j), the thick solid line is the 5% significance level, and the thin solid line indicates the cone of influence.
