expansion between 1988 and 2025, characterized by substantial
increases in lake area, water level, and water storage,

consistency with terrestrial water storage (TWS) variations;
during 2002--2019, TWS anomalies lagged approximately one year

hydrological regulation processes within the regional water

It is recommended to strengthen monitoring and early warning
systems in response to the ongoing expansion of Siling Co; The
one-year lag of TWS anomalies behind LWSC reflects an
interannual regulation process. This process results from
differences in response times among various water storage
components. It is recommended to strengthen monitoring and early

Co; The one-year lag of TWS anomalies behind LWSC reflects an

differences in response times among various water storage
components. Lakes on the Tibetan Plateau are sensitive
indicators of climate change. Their water storage variations
play an important role in regional hydrological processes and
ecological security. This study is based on multi-source remote
sensing and meteorological data from 1988 to 2025. Lake area was
extracted using the MNDWI and the Otsu threshold method.
HYDROWEB water level data were used to establish an area-water
level relationship. This relationship was then applied to
reconstruct a long-term water level time-series and estimate
changes in lake water storage. GRACE/GRACE-FO data and
meteorological observations were further analyzed to identify
the driving factors. The results show that Siling Co experienced
a persistent expansion over the study period, with the lake area
increasing by 805.83 km$^{2}$, water level rising by 14.33 m,
and water storage increasing by 30.42 km$^{3}$. Correlation
analysis indicates that air temperature, precipitation, and
evaporation jointly influenced lake water storage variations.
Among these factors, precipitation plays a relatively more
important role. During 2002--2019, lake water storage changes
(LWSC) were highly consistent with terrestrial water storage
(TWS) variations. However, TWS anomalies lagged approximately
one year behind LWSC. These findings improve the understanding
of the long-term hydrological responses of Siling Co to climate
change. They also provide a scientific basis for water resource
management and infrastructure planning in the region.}",
