• An ice core-drilling program was carried out at the accumulation area of Dasuopu glacier(28°23'N, 85°43'E, 7100m a.s.l.) in the central Himalayas in 1997. The ice core was analyzed continuously for stable isotopes(δ18O), and major ions throughout the core. Cycles indicated by δ^<18>O, cations were identified and counted as seasonal fluctuations as annual increment from maximum to maximum values. Reconstructed 300-year annual net accumulation(water equivalent) from the core, with a good correlation to Indian monsoon, reflects a major precipitation trend in the central Himalayas. The accumulation trend, separated from the time series, shows a strong negative correlation to Northern Hemisphere temperature. Generally, as northern hemisphere temperature increases 0.1°C, the accumulation decreases about 80mm, reflecting monsoon rainfall in the central Himalayas has decreased over the past decades in the condition of global warming.
