From: Mechanisms of multiyear variations of Northern Australia wet-season rainfall
Coherence-squared (black curve) and phase (red dotted) spectra of Niño3.4 index with area averaged rainfall in (a) NW, and (b) NE. The scale for coherence squared is on the left ordinate and for the phase (degrees, below 180° means Niño3.4 is leading and above 180° means Niño3.4 is lagging) is on the right ordinate respectively. The dashed blue line indicates the 95% confidence level for the coherence squared estimates. The bandwidth of the spectra is also shown at the top left.
