The Characteristics Of Monsoon: Evidence From Between Western And Eastern Sample Plots Beside Gaoligong Mountain In Yunnan Over The Past 60 Ka And Their Comparison With Oceanic Records

South Asian monsoon, one of the most typical environmental driving force ,plays an important role in climate of southern part of China, especially Yunnan province. High resolution sediment core records from Tengchong Beihai wetland and Shangri-La Napahai Lake located at the both sides of Gaoligong Mountain in Yunnan ,have provided insights into the factors that control the strength of the South Asian monsoon. South Asia monsoon has influence on precipitation of Yunnan area and brings the signal of rapid climate change from the ocean into two places respectively. On the basis of correlating some significant proxies, such as TOC,,natural thermoluminescence,δ13C,grain-size and pollen assemblages, from the Napahai lake, Shangri-la and Beihai wetland, Tengchong with sedimentary rhythm andδ18O record since 60kaBP from Bay of Bengal, we find all of them have been closely affected by the Indian Monsoon system. Because of the difference in their latitudinal, longitudinal and sea-land situations, however, the climatic records clearly have a differential affinity to the summer monsoon or winter one. In proxies such as Pteridaceae, Picea, Artemisia, Polypodiaceae and Potamogeton are sensitive to reflect the climate change, and are in comparison with other alternative indicators. In comparison between Shangri-La Napahai pollens and Tenchong Beihai ones, the paper analyzes to determine the two different properties of India winter and summer monsoon and claims that Gaoligong mountain is an important monsoon buffer zone: Tengchong wetland records summer monsoon signal readily, while Shangri-La Napahai lake is more sensitive to winter monsoon.By compared to sea records, the study reveals the occurrence of a number of terrestrial rapid climate change events in unstable areas and there is a positive response and the relationship. For example,the most impressive climatic shock over the past 60 ka BPis a great thermal and wet event that happened roughly from 37 ka BP to 32 ka BP and was evidently marked within both the Beihai's and Napahai's sedimentary sequences. Discordantly, that event can not be recognized in the marine records. We deduce from the correlation between the continental deposit and marine deposit that the control of the regional climatic event originated in the land side but sea side during the late MIS3. It is likely that an extreme worming up at that phase at Tibetan Plateau, which resulted in decline of the Indian winter monsoon,other changes of the atmospheric circulation , even insolation, was responsible for the event. The geomorphologic configuration plays an important role in the monsoonal precipitation as well.
