Wavelet decomposition of 1941–2012 precipitation (green line), air temperature (red line), and water–vapor pressure (blue line) averaged over the area (22° N–24° N, 100° E–105° E) in southwestern China: (a) standard sequences; ((b), (c), (d), and (e)) wavelet components at scales of 16 a, 32 a, and 64 a and beyond corresponding to quasi-periods of 20 a, 40 a, and 70 a and beyond, respectively; dashed black circles denote the recent warm–dry collocations.
