[1] The influence of the Asian monsoon on the delta(18)O composition of precipitation is investigated on the basis of the ECHAM-4 Atmospheric General Circulation Model (AGCM), fitted with stable isotopic tracers. The model is forced with prescribed sea surface temperatures (SST) over the last few decades of the 20th century. The simulated climate and climate - stable isotope relationships are validated with observational data from the International Atomic Energy Agency - Global Network of Isotopes in Precipitation (IAEA-GNIP) and reanalysis data. The model shows deficiencies when simulating interannual variations of monsoon precipitation, but the associated mons...
