Abstract Given the sensitivity of snow to climate change and its critical role in hydrological cycle alpine regions, it is essential reduce biases meteorological forces for driving models. This study, taking Manas River Basin (MRB) Xinjiang China as test bed, aims quantify uncertainties hydrometeorological variables from 24 NASA Earth Exchange Global Daily Downscaled Projections (NEX‐GDDP‐CMIP6) simulations further these using a Cycle‐Consistent Generative Adversarial Network (CycleGAN). The bias‐corrected CMIP6 data are then used drive Soil Water Assessment Tool model calibrated with both runoff water equivalent (SWE) through dual‐objective approach future projections. results indicate that: (a) Model uncertainty brought by different models primary source original outputs. CycleGAN demonstrates substantial effectiveness reducing uncertainty; (b) Most subbasins MRB will experience absolute SWE reduction future, changes varying significantly across elevation bands, decreasing 30%–60% baseline levels end century; (c) has an increasing trend projected increases ranging 1.34% under SSP126 24.56% SSP585. As rain‐to‐snow ratio rises snowmelt shifts earlier, low flows increase during dry period, elevating spring flood risks. These findings provide crucial insights management resources snow‐dominated watersheds.
