Fig. 6 Spatial distribution of average annual precipitation (a) and average annual potential evapotranspiration (b), temporal changes in annual precipitation (c) and annual potential evapotranspiration (d), and variations of precipitation (e) and potential evapotranspiration (f) at different water conservation depths in the IRD during 1975-2020. The different colors in Figure 6e and f represent the precipitation or potential evapotranspiration corresponding to different water conservation depths. The box plots represent the range of values for precipitation or potential evapotranspiration at different water conservation depths. Box boundaries indicate the 25th and 75th percentiles, and whiskers below and above the box indicate the 10th and 90th percentiles, respectively. The black horizontal line within each box indicates the median.
