Evaluation of the Spatial Impact of Snowmelt Processes on Vegetation Dynamics in Mongolia

Key Points

• The research assesses how snowmelt impacts vegetation responses and soil moisture dynamics in Mongolia.
• Utilized satellite observations and reanalysis data from 2000 to 2018.
• Conducted spatial correlation analysis between snowmelt indicators, temperature, precipitation, and NDVI.
• Identified regional variations in vegetation response to snowmelt and environmental factors.
• Snowmelt significantly impacts vegetation dynamics in central-western Mongolia, especially around the Altai and Hangai Mountains.
• In eastern Mongolia, temperature and precipitation play a more critical role compared to snowmelt.
• Southern arid regions primarily rely on snowmelt as a water source, promoting vegetation growth.
• The effects of snowmelt vary monthly, with specific periods more sensitive to changes.
• In high-elevation areas around the Altai Mountains, increased snowmelt rates tend to hinder vegetation growth.
