Normal>Based on 4 ²³⁰Th dates and 370 stable oxygen isotope ratios (δ¹⁸O) obtained from a stalagmite collected from Yuhua Cave, Jiangle, Fujian Province, and combined with the age calibration of the top 100 years using the annually band counting stalagmite from Heshang Cave, an high-resolution oxygen isotope profile of the past 500 years was established. Comparison of the stalagmite δ¹⁸O record with instrumental precipitation data at Yong’an in the past 60 years indicates a high parallelism between the δ¹⁸O record and the total summer months precipitation, suggesting that the stalagmite δ¹⁸O is a good proxy for the local summer monsoon precipitation
