Fig. 2: Power spectra of ISVs of individual summer monsoons.
From: Intraseasonal variability of global land monsoon precipitation and its recent trend
Power spectra of the 3-day running mean precipitation anomalies (mm day−1) averaged over each monsoon region for a NH and b SH during the summers of 1979–2018. Daily climatology is removed to obtain the anomalies. Each monsoon precipitation series is normalized before the spectrum analysis. Dashed lines denote the corresponding 90% confidence level.
