Results of wavelet analyses of weekly Niño 3.4 SSTA vs. weekly leptospirosis incidence for 2004–2019: (Panel a) continuous wavelet transform (CWT) variations; (Panel b) wavelet power of CWT; (Panel c) cross-wavelet transform (XWT) variations; (Panel d) wavelet power of XWT; (Panel e) wavelet coherence (WTC); (Panel f) wavelet power of WTC; and (Panel g) reconstructed time series for 2004–2019. There are two patterns of correlation. 1. LI peaks after about 3.3 months = 16 weeks (varies 6–32 weeks) of Niño 3.4 SSTA troughs. 2. LI peaks after about 6.8 months = 29 weeks (varies 20–46 weeks) of Niño 3.4 SSTA peaks
