The rise and fall of this layer influence the surface elevation of the 0°C isotherm in mountainous regions, thereby affecting the freeze-thaw processes of water in these areas.By analyzing upper-air data from 39 high-altitude observation stations in western China since 1979 (with some stations having later observation records), including standard-level heights and temperatures, the summer (June-August) 0°C isotherm height was calculated. Using Kriging interpolation and regression analysis, the variation of the summer 0°C isotherm height in the Qaidam Basin from 1985 to 2018 was derived. Additionally, a fishnet tool was employed to statistically assess the 0°C isotherm height change per 100 km grid.
