为探讨南极、北极强信号区域海冰变化 ,青藏高原陆面热力状况与北半球大气环流及中国气候变异的遥相关特征以及“三极”因子间的“互反馈”机制 ,应用遥相关等统计方法研究了影响东亚以及中国区域气候变化特征前期“三极”强信号特征 ,探讨了两极海冰与高原陆面水热状况之间的“耦合”影响及其“互反馈”相关特征 ,比较了“三极”前期因子对中国夏季气候变异的贡献程度及其动力结构形成的影响特征 ,并从全球海 -陆 -气 -冰相关定性模型来认识全球气候变化与中国区域气候变异的形成机制。
In order to discuss the teleconnection between sea ice in the Antarctic and the Arctic strong signal region, the terrestrial thermal condition in the Tibetan Plateau and the atmospheric circulation in the northern hemisphere and China’s climate variability, and the “mutual feedback” mechanism among the “three poles” Methods The characteristics of the strong “three-pole” signal in the early prophase of the regional climate change in East Asia and China were studied. The “coupling” effect between the polar sea ice and the hydrological conditions on the land surface of the plateau and the related characteristics of “mutual feedback” were discussed. The contribution of the “three-pole” factor to the contribution of summer climate variability in China and its dynamic structure formation, and the global sea-land-gas-ice correlation qualitative model to understand the global climate change and the formation mechanism of regional climate variability in China.
