Abstract

Key message: Compared with annual tree-ring cellulose δ¹⁸O, intra-annual cellulose δ¹⁸O has potential to reconstruct precipitation with higher resolution and stronger signal intensity. Abstract: Annual tree-ring cellulose oxygen isotope values (δ¹⁸O) of Fokienia hodginsii provide a promising proxy of monsoon-season precipitation in Southeast China. Measuring intra-annual cellulose δ¹⁸O values may reveal the seasonal variability of precipitation and the associated climate influences. Here, we examine intra-annual variation of cellulose δ¹⁸O values in Fokienia hodginsii and Cryptomeria fortune from Fujian Province, Southeast China. Both species exhibited considerable intra-annual variations in cellulose δ¹⁸O (range ~6 ‰) with a consistent pattern of enriched values near the annual ring boundary and depleted values in the central portion of the ring. Seasonal patterns in the tree-ring δ¹⁸O values generally followed changes in precipitation δ¹⁸O values. Compared with annual tree-ring cellulose δ¹⁸O, intra-annual cellulose δ¹⁸O has potential to reconstruct precipitation with higher resolution and stronger signal intensity. July tree-ring cellulose δ¹⁸O is significantly correlated (r = −0.58, p < 0.05) with July precipitation, and June–August tree-ring cellulose δ¹⁸O and annual tree-ring cellulose δ¹⁸O, respectively, explain 52 and 41 % of the actual variance of April–August precipitation. In addition, May–October cellulose δ¹⁸O values during El Niño years are higher than in La Niña years, and April to October rainfall is lower in El Niño years than in La Niña years. Combining the significant correlations between inter-annual cellulose δ¹⁸O values and sea surface temperatures in the central tropical Pacific, our results support the hypothesis that El Niño–Southern Oscillation affects tree-ring cellulose δ¹⁸O in Southeast China by modulating seasonal precipitation.
