Fig. 3: Mechanism of concentration effects on TWS.
From: More concentrated precipitation decreases terrestrial water storage
a, Dependence of water-year mean net surface shortwave (SW) radiation on the daily rainfall Gini coefficient (GP), conditional on climatological mean precipitation. b, Marginal GP effect on TWS controlling for shortwave radiation anomalies, to isolate the effect of temporal precipitation distribution, averaged across the three precipitation data products (blue line). The full GP effect on TWS from Fig. 2 is shown in black, for comparison, with dotted lines showing full range covered by 2 standard errors of the estimate across data products. c, Intensity-partitioning effect contribution to the full effect of GP on TWS, estimated as the ratio of median distribution to full effects, for the mean of the three precipitation data products (thick solid line) and individually. In a–c, the average effect across the GEWEX-SRB52 and NASA-EBAF53 radiation budget datasets is shown; results for individual data products are shown in Supplementary Fig. 1. d, Marginal effect of GP on water-year total simulated evaporation (ET) from GLEAM54, conditional on climatological mean precipitation. The shaded areas in a, b and d show 2 standard errors of the estimate.
