主 题:Northern Tibetan Plateau Wet/dry change Warm period similarity Driving mechanism Future assessment
摘 要:The northern Tibetan Plateau is a climatically sensitive zone influenced by monsoon and westerly *** summer,water vapor transport can reach Qinghai Lake and the eastern section of the Qilian Mountains;in winter,westerly winds mainly control the *** article compares the wet/dry changes in the region during the mid-Holocene(MH)warm period,the medieval climate anomaly(MCA),the current warm period(CWP),and the future warm period from the perspective of *** found that the MH warm period was mainly affected by the orbit-controlled East Asian summer monsoon,and the region showed warm and humid climate *** MCA was mainly controlled by solar radiation,and there was a warm and dry *** CWP and the future warm period are mainly controlled by the rise in temperature caused by the increase in greenhouse gases,and the climate is becoming more *** wet/dry patterns in the CWP and the future warm period in the next century on the northern Tibetan Plateau are similar to those in the *** warming will lead to the expansion of the westerly belt and a gradually humid *** future wet/dry changes will be more similar to the MH warm period.
