Abstract. The change rule and the driving mechanism of the Asian monsoon (AM) is widely concerned. In this paper, we have decomposed the Huangye cave δ18OR datasets (proxy for AM) into variations at different time scales with the Ensemble Empirical Mode Decomposition (EEMD) method, obtained the main cycles of the Asian monsoon changes and drought and wet periods in the last millennial history, analysed and predicted the precipitation trend at the local site in the future. Meantime, we have also decomposed 10Be (proxy for solar activity) and average Northern Hemisphere Temperature (NHT) datasets with the EEMD method. The relationship among the components of δ18OR, 10Be and NHT shows that NHT as well as solar activity has the obvious driving effect on the AM at millennial scales, and NHT with the frequency and amplitude modulations can influence the intensity of the AM more directly and obviously than the solar activity in the last 1000 years.

Short summary
This paper is mainly about the change rule and the driving mechanism of the Asian monsoon in the last millennial. We obtain the main cycles of the Asian monsoon changes, drought and wet periods in the history, and can predict the precipitation trend at the local site in the future. It also shows that solar activity and average Northern Hemisphere Temperature can influence the intensity of the Asian monsoon in the different degree in the last 1000 years.
