Stable carbon isotope in tree rings from Huangling, China and climatic variation

摘要

By using a single-year discrimination chronology detrended from a δ~(13)C chronology from Chinese pine (Pinus tabulaeformis) tree rings and meteorological data, the δ~(13)C-dimatic response is analyzed. The results show that high-frequency δ~(13)C is significantly related to both temperatures of June (with r = -0.65) and the total precipitation of May, June and July (r = -0.46). This suggests that δ~(13)C records reflects some features of the East Asian summer monsoon. In addition, temperature departure for June is reconstructed from a transfer function developed with δ~(13)C-climatic response.
