Northeast Asian Climatic Variability Over the Last 300,000 Years

地质证据和大气环流模式实验表明，季风气候对轨道变化引起的日射变化的反应非常强烈。来自东北亚和西北太平洋的多气候资料表明，这些陆地和海洋环境受到东北亚季风的影响，对全球气候变化的响应具有复杂的时间和地理变化。利用高分辨率的陆地，海洋和大气气候信息产生的花粉，放射虫，氧同位素，和海洋岩芯沉积物的矿物学分析，晚更新世气候变化的区域响应将examninated。通过两个完整的冰期到冰消期循环，将确定东北亚季风强度和持续时间的变化。这项工作是重要的，因为它将使东北亚季风的经验为基础的概念模型的建设，一个独立的模式，以比较模拟的基础上数值环流模式。

Geologic evidence and general circulation model experiments show that the monsoon climates respond very strongly to insolation changes induced by orbital variations. Pleoclimate data from northeast Asia and northwest Pacific Ocean suggest that these terrestrial and marine environments, influenced by northeast Asian monsoon, respond to global climate changes in a complex way that varies temporally and geographically. Using high resolution terrestrial, marine, and atmospheric climatic information generated from analyses of pollen, radiolaria, oxygen isotopes, and mineralogy of sediments from marine cores, the regional response to late Pleistocene climate variations will be examnined. The changes in the intensity and duration of the northeast Asian monsoon through two complete glaciation to deglaciation cycles will be determined. This work is important because it will enable construction of an empirically based conceptual model of northeast Asian monsoon; an independent model to compare with simulations based on numerical general circulation models.
