Fig. 5: Regional space-time spectra for historical and Future projections.

Space-time spectrum performed on daily precipitation anomalies for AAPM-Historical (a) and AAPM-SSP370 (b) over the region 10°S − 30°N and 80°E − 95°E. The X-axis represents frequency in day−1, and the Y-axis represents meridional wave number. The vertical dashed lines in each plot show the frequency corresponding to time periods of 25 days and 80 days.
