Investigation of the Dynamics of Core-Mantle Interactions & the Core-Mantle Boundary

地球物理学各个领域的最新发展表明，地核-地幔边界区表现出非常丰富的行为范围。对于最近获得的大量数据，似乎无法给出简单的解释。pi将对该地区进行研究，重点关注两个方面：1)地核与下地幔对流相互作用模式；不同核幔耦合机制的相对重要性；2)核幔边界边界层结构，利用简单的动力学模型和数据对核幔边界结构进行约束。

Recent developments in a variety of fields of geophysics have revealed that the core-mantle boundary region exhibits a very rich range of behavior. Simple explanations of the wide range of data which have recently become available do not seem to be forthcoming. The PIs will investigate this region, concentrating on two aspects: 1) the modes of interaction between core and lower mantle convection; and the relative importance of different mechanisms of core-mantle coupling; and 2) the structure of the boundary layers at the core-mantle boundary, using both simple dynamical models and data to bound structure at the core-mantle boundary.
