气候动力学的标度律及其相关的层次结构

This work focuses on the study of the scaling property of climate variations. Through analysis of climate temperature variation signals and data from atmospheric turbulent boundary layer, we demonstrate that the She-Leveque hierarchical similarity is a general property of atmospheric variations ranging from long-range climate temperature changes to high-frequency turbulent fluctuations. Hierarchical similarity parameter can be used for describing properties of climate changes. The study opens a new avenue for characterizing climate variations.

气候动力学系统涉及到多个时间—空间尺度相互作用的复杂系统，其运动涨落具有较宽的振幅范围。我们将应用最近发展的湍流层次结构理论来研究气候动力学尺度运动之间的关联，并从大尺度慢速变化运动结构对小尺度快速变化结构进行统计预测。在建立气候动力学层次结构理论的同时，我们将对中国气候及北半球气候结构标度律给出定量描述。
