英文摘要	We present a long-term seasonal tree ring cellulose oxygen isotope (delta O-18(c)) time series created by analyzing four segments (S1, S2, S3, and S4) per year during the period of 1951-2009 from southeastern Tibetan Plateau. This intraseasonal delta O-18(c) reveals the onset and mature phase of the summer monsoon precipitation in this region. Analysis indicates that the delta O-18(c) of S1 has the strongest correlation with precipitation during the regional monsoon onset (29-33 pentads, May 21-June 10, r = -0.69), and the delta O-18(c) values for S2, S3, and S4 correlate strongly with June, July, and August precipitation, respectively. Combined delta O-18(c) of S2, S3, and S4 shows the most robust correlation (r = -0.82) with the mature-phase monsoon precipitation (June-July-August, JJA), passing rigorous statistical tests for calibration and verification in dendroclimatology. These results demonstrate the feasibility in using long-term intraseasonal delta O-18(c) to reconstruct the Asian summer monsoon's intraseasonal variations.
