Abstract


As the environment, one of the driving forces of the Indian monsoon , especially on the South China Yunnan climate environment plays an important role . On both sides of Beihai Gaoligongshan wetlands and Shangri-La Napahai climate change is mainly influenced by the Indian monsoon , we study the ideals of the Indian monsoon area . Sedimentary rhythm of the Bay of Bengal through the comparison of the of Beihai and Shangri-La Napahai organic carbon content , δ13C , particle size , thermal luminescence deposition indicators and pollen indicators , since the reference to 60 ka BP interbedded with δ18O records and found that they are with the Indian monsoon The system there is a close association . However, due to differences in latitude and longitude , and the distribution of land and sea , are significantly different in summer and winter monsoons throughout . In many palynological indicators , of Pteris , spruce , Artemisia, Polypodiodes well Potamogeton genus sensitively reflect the warm and cold wet and dry climate change , and the relations are very good compared with other alternative indicators , and high Gaoligong the Shandong side of the Shangri-La Napahai pollen were analyzed to determine the summer and winter monsoon in India on the impact of the two characteristics ; compared through both sides of the record can be found Gaoligongshan monsoon activity isolation belt : the east side by the Indian strong winter wind control , while the west side is more direct response of the Indian summer monsoon . By land and sea climate comparison , the remote climate contrast and high-resolution climate study reveals the relevance of some land instability in the region of rapid climate change events in the waters away the existence of a positive response and climate change . For example , occurred at about 36 ka BP-32 ka BP strong warm and humid climate events reflected into the North Sea and the Napa Lake Basin sedimentary sequence , to become the most remarkable phenomena in the past 60 ka BP , but the lack of sea area recorded strong echoes . Land and sea records to contrast results of MIS3 late control factors of the regional climate events from the land rather than the sea , and the Tibetan Plateau in special warming in this period led to the recession of the winter monsoon in India , other atmospheric circulation patterns change , and solar irradiance are likely to be significant the main cause of the formation of the climate events . In addition , there can not be ignored . Terrestrial landforms monsoon precipitation effects
