Multi-Scale Analysis of East Asian Winter Monsoon Evolution and Asian Inland Drying Force
详细信息   
摘要

On the glacial-interglacial cycles of the Milankovitch theory research is the mature and generally accepted astronomical theory of climate change. With its successful application to the nonlinear and nonstationary data, the new time series technique Empirical Mode Decompositon (EMD)is introduced in order to gain insight into the paleoclimate. The results showed that: 1) the quasi -100 ka, 40 ka and 20 ka are discovered evidently, 100 ka cycle fluctuations play a leading role to East Asian winter monsoon in 01 Ma B.P; 2) the East Asian winter and summer monsoon evolution in different periods were relatively strong and weak position, and even some stage or another both a considerable strength of growth and decline, in the 100 ka, 40 ka and 20 ka scale; and 3) 100 ka, 53 ka and 27 ka cycle fluctuations play a leading role to the evolution of mass accumulation rates of deposits at Zhaojiachuan. The Tibetan Plateau uplifting resulted in an increasing role in Asian monsoon and Asian inland drying evolution.
