摘要	In southeastern China (SEC), the precipitation amount produced by the East Asian summer monsoon (EASM) is almost equivalent to that during the non-summer monsoon (NSM) period, both of them significantly affecting agriculture and socioeconomy. Here, we present a seasonally-resolved stalagmite delta O-18 record (delta O-18(s)) for the interval 1810-2009 AD from E'mei cave, Jiangxi Province, SEC. The comparison between delta O-18(s) and instrumental data indicates that the delta O-18(s) variability is primarily controlled by the precipitation seasonality (i.e., the ratio of EASM/NSM precipitation) modulated by the El Nino/Southern Oscillation (ENSO) on interannual to interdecadal timescales. Higher (lower) delta O-18(s) values thereby correspond to lower (higher) EASM/NSM ratios associated with El Nino (La Nina) events. Significant correlations with ENSO and the Pacific Decadal Oscillation (PDO) indicate that the precipitation seasonality in SEC is remarkably influenced by ocean-atmosphere interactions, with lower (higher) EASM/NSM ratios during warm (cold) phases of ENSO/PDO. The progressive increase in delta O-18(s) since 2005 AD may reflect a strengthening of the central Pacific El Nino under continued anthropogenic global warming. The relationship between seasonal precipitation and delta O-18(s) with ENSO/PDO requires further studies.
