Figure 6.
The upper charts show the tenth percentile precipitation data before and after Power Transformation adjustment, highlighting smoother seasonal variation and better model agreement. The lower charts display raw and adjusted ninetieth percentiles, showing improved model alignment and less variability after correction. Observations and model data from A C C E S S C M 2, A C C E S S E S M 1.5, E C Earth 3, H a d G E M 3 G C 3 1 L, M I R O C E S 2 L, and M P I E S M 1.2 H R are compared across months. The horizontal axis shows the months, and the vertical axis indicates precipitation in millimetres per day.Performance of power transformation (PT) bias correction method applied on 10th and 90th percentiles of CMIP6 precipitation data sets in southern Ethiopia
