     abstract = "{Climate change intensifies hydrological cycles, leading to an increased
        variability in terrestrial water storage anomalies (TWSAs) and a
        heightened drought risk. Understanding the spatiotemporal
        dynamics of TWSAs and their driving factors is crucial for
        sustainable water management. While previous studies have
        primarily attributed TWSAs to regional factors, this study
        employs wavelet coherence, partial correlation analysis, and
        multiple linear regression to comprehensively analyze TWSA
        dynamics and their drivers in the Hengduan Mountains (HDM)
        region from 2003 to 2022, incorporating both regional and global
        influences. Additionally, dry{\textendash}wet variations were
        quantified using the GRACE-based Drought Severity Index (GRACE-
        DSI). Key findings include the following: The annual mean TWSA
        showed a non-significant decreasing trend (‑2.83 mm/y, p >
        0.05), accompanied by increased interannual variability.
        Notably, approximately 36.22\% of the pixels in the western HDM
        region exhibited a significantly decreasing trend. The Nujiang
        River Basin (NRB) (‑17.17 mm/y, p < 0.01) and the Lancang
        (‑17.17 mm/y, p < 0.01) River Basin experienced the most
        pronounced declines. Regional factors{\textemdash}particularly
        precipitation (PRE){\textemdash}drove TWSA in 59\% of the HDM
        region, followed by potential evapotranspiration (PET, 28\%) and
        vegetation dynamics (13\%). Among global factors, the North
        Atlantic Oscillation showed a weak correlation with TWSAs (r =
        ‑0.19), indirectly affecting it via winter PET (r = ‑0.56, p <
        0.05). The decline in TWSAs corresponds to an elevated drought
        risk, notably in the NRB, which recorded the largest GRACE-DSI
        decline (slope = ‑0.011, p < 0.05). This study links TWSAs to
        climate drivers and drought risk, offering a framework for
        improving water resource management and drought preparedness in
        climate-sensitive mountain regions.}",
