Popis:	Stable isotopes in precipitation sampled at different locations and altitudes over the volcanic island of Cheju, Korea, were analysed to elucidate the circulation patterns of water over the island where groundwater is a major water resource and the characteristics of stable isotopes in precipitation inputs to the hydrological cycle are a very important indicator of groundwater flow. Areal and altitudinal variation of stable isotopes in precipitation showed the contribution of different air masses to the precipitation on mountain slope areas and in the atmosphere above and below the boundary at around 1000 m a.s.l. Seasonal change of the isotopic composition of precipitation also gave a good illustration of the influence of the dominant regional air currents on precipitation inputs.
