Wavelet power spectra of a, b the DW1 amplitude averaged within 10°S–10°N, c, d the DE3 amplitude averaged within 0°–20°N, e, f the DE3 amplitude averaged within 0°–20°S, and g ONI. The division of DE3 into the two latitudinal regions is due to its equatorial asymmetry natural. The powers are shown on the log2 scale. Black dots indicate the QBO period as a function of time. The QBO period is defined as the location of maximum values, the period ranging from 1.5 to 3.5 years. Black curves indicate the cone of influence zone of the wavelet analysis
