Dynamo Models of Paleomagnetic Secular Variation

这是一个联合收割机的项目， 长期高质量古地磁时间序列分析 来自湖泊沉积物的变化，目的是 解释全新世的磁场变化， 外核动力学的术语。 该研究包括 两个部分：（1）分析已发表的古地磁长期 来自南北美洲、澳大利亚和欧亚大陆的变异数据 使用传播和站立的动态一致模型 波场，（2）运动发电机的数值模拟 具有永久偶极场和共存的长期变化。 目的是找出低频的来源 古地磁长期变化和确定动力学 它所起源的外核的结构。

This a project to combine results from dynamo theory with analysis of high quality paleomagnetic time series of secular variation derived from lake sediments, for the purpose of interpreting magnetic field variations through the Holocene in terms of the dynamics of the outer core. The research consists of two parts: (1) an analysis of published paleomagnetic secular variation data from North and South America, Australia and Eurasia using dynamically consistent models of propagating and standing wave fields, and (2) numberical simulations of kinematic dynamos with permanent dipolar fields and coexisting secular variation. The object is to identify the source of the low frequency paleomagnetic secular variation and to determine the dynamical structure of the outer core from which it originates.
