Description
Summary:P5; Relationship between the δ 13C of tree ring cellulose from Pinus Koraiensis and climate parameters was investigated. A significantly negative correlation between δ 13C and meanlow-cloud amount from May to July was discovered, which contributes to reconstructing the meanlow-cloud amount from May to July at Antu in recent 200 years. Periodicals of quasi-8-year,quasi-4-year and quasi-2-year were detected both in δ 13 C series and in the reconstructed lowcloud amount series with 95% confidence level. Quasi-8-year period may reflect the integratedinfluence of solar activity, monsoon activity and local regional factors. Quasi-4-year and quasi-2-year periods indicate the influences of ENSO and Quasi Biennial Oscillation (QBO) of EastAsian monsoon, respectively.
