亚洲夏季风指数数据集（过去15万年）

通过长期瞬变古气候数值模拟，分析轨道尺度上“日射强迫-季风响应”机制，探讨东亚区域气候变化对地球轨道参数引起太阳辐射变化的响应。由亚洲夏季风的长期演化序列可见，夏季风呈现与负岁差同步的2万年周期。岁差变化对北半球夏季太阳辐射强弱起主要作用。这些结论与以往的研究结果一致，佐证了CCSM3瞬变数值试验结果的可靠性。

Through long-term transient paleoclimate numerical simulations, we analyzed the 'insolation forcing-monsoon response' mechanism at orbital scales, and investigated the response of East Asian regional climate change to variations in solar radiation induced by Earth's orbital parameters. Analysis of the long-term evolution sequence of the Asian summer monsoon reveals that the monsoon exhibits a 20,000-year cycle synchronized with negative precession. Precessional variations play a dominant role in regulating the intensity of summer solar radiation in the Northern Hemisphere. These conclusions are consistent with previous research findings, confirming the reliability of the transient numerical experimental results from CCSM3.
