The observed GWS anomalies are relative to the mean during 2006‒2018 and their decomposed time series (2019‒2030) under four scenarios. Scenario I: normal GW use (G1) + precipitation climatology (P1); Scenario II: low GW use (G2) + P1; Scenario III: G1 + a wet climate (P2); and Scenario IV: G2 + P2. Solid lines are observed or simulated GWS anomalies, and dashed lines are corresponding decomposed time series (see the “Methods” section).
