Short Summary

This study reconstructed water level changes for Lake Zaysan and Lake Ulungur in Central Asia from 2003 to 2024 using satellite altimetry data, revealing significant fluctuations primarily controlled by runoff processes and highlighting their sensitivity to climate change.

Objective

• To systematically reconstruct water level changes of Lake Zaysan and Lake Ulungur from 2003 to 2024 using high-precision altimetry data.

Study Configuration

• Spatial Scale: Lake Zaysan and Lake Ulungur in arid Central Asia.
• Temporal Scale: 2003 to 2024.

Methodology and Data

• Models used: No specific hydrological or climate models were explicitly mentioned for the analysis.
• Data sources: High-precision altimetry data from ICESat, CryoSat-2, and ICESat-2 satellites.

Main Results

• Lake Zaysan experienced significant water level fluctuations: 5.01 m (21.01 Gt water mass change) in 2010, 5.12 m (21.47 Gt) in 2013, and 3.53 m (14.80 Gt) in 2024.
• Lake Ulungur also exhibited notable water level changes during the same period.
• Water level variations in both lakes are primarily controlled by runoff processes.
• A highly significant positive correlation exists between lake level anomalies and discharge anomalies.
• A low correlation between water levels and precipitation indicates a pronounced lagged effect of snowfall.
• Lake water level fluctuations are driven by a combination of spring snowmelt runoff and summer precipitation.
• These Central Asian lakes show a sensitive response to environmental changes under climate warming.

Contributions

• Enriches observational data on regional lake dynamics in Central Asia.
• Provides a scientific basis for water resource management and future climate adaptation strategies in arid regions.
