     abstract = "{The interaction between terrestrial water storage (TWS) and drought is a
        crucial aspect of hydrological dynamics. We utilized data from
        the gravity recovery and climate experiment (GRACE) to derive
        the TWS of Yunnan from 2011 to 2020 and calculated the GRACE
        drought severity index (GRACE-DSI) to assess hydrological
        drought events based on the run theory. To understand the
        underlying causes of drought, we analyzed precipitation data
        alongside the spatial and temporal distribution of drought
        events. Each component of TWS was obtained through hydrological
        models, and we used random forest to determine the contribution
        of each component to drought. Our findings revealed that Yunnan
        experienced four drought events from 2011 to 2020, with the
        third and fourth drought events between 2019 and 2020 being
        particularly severe. The occurrence of these drought events was
        primarily attributed to a relative lack of precipitation. Among
        the components of TWS, water storage in groundwater, canopy,
        soil, and lake were identified as having the highest
        contribution rates to drought. We also applied random forest to
        simulate the contribution rates of each TWS component to drought
        in other regions of China. Our analysis confirmed that
        groundwater in the North China Plain, lake, and soil water in
        the Yangtze River middle-downstream Plain, snow, and groundwater
        in Tianshan Mountain were the components with the highest
        contribution rates to drought, respectively. Finally, we found
        that the contribution of TWS components to drought in different
        regions of Yunnan Province was significantly different. This
        novel method was valuable for hydrological drought management.}",
