Fig. 2: Land-drying effect of more concentrated precipitation.
From: More concentrated precipitation decreases terrestrial water storage
a, Standardized regression coefficients of water-year total precipitation (dark blue), mean 2 m air temperature (red) and daily rainfall Gini coefficient (GP, light blue) anomalies on GRACE TWS25 anomalies. The effect of GP on TWS, being conditional on climatological mean precipitation, is shown for mean precipitation of 1,000 mm (the global population-weighted mean). Error bars show 2 standard errors of the estimate. b, Marginal effect of GP on TWS, conditional on mean precipitation, for three precipitation data products. Shaded areas show 2 standard errors of the estimate. c, Marginal GP effects on TWS estimated at the scale of HydroSHEDS main river basins51, averaged across the three data products. Results for individual data products are shown in Extended Data Fig. 5. Effects are significant at P < 0.05 and of like sign across in at least two of the three data products, except in hatched basins.
