Abstract: The seasonally varying moisture balance in a montane forest of Southeast Asia is reconstructed for the 20th century from the oxygen isotopic composition (δ 18 O) of subannual tree cellulose samples of Pinus kesiya growing at 1,500 m elevation on Doi Chiang Dao in northern Thailand. The cellulose δ 18 O values exhibit a distinctive annual cycle with amplitude of up to 12 ‰, which we interpret to represent primarily the seasonal cycle of precipitation δ 18 O. The annual mean δ 18 O values correlate significantly with the amount of summer monsoon precipitation, and suggest a temporal weakening relationship between the South Asian monsoon and El Niño-Southern Oscillation over the late 20th century. The cellulose δ 18 O annual maxima values, which reflect the dry season moisture status, have declined progressively over the 20th century by about 3.5 ‰. We interpret this to indicate a change in the contribution of the isotopically distinct fog water to the dry season soil moisture in response to rising temperature as well as deforestation.
