Geomagnetic Reversal Constraints on the Properties of, and Processes Acting in, the Earth's Deep Interior

PI将继续开发新的方法来分析磁场反转年表的统计结构，特别是放宽适用于所有以前的反转年表统计分析的限制，即反转发生在瞬间。这样做的一个主要原因是为了检查地核在包括极性转变在内的时间间隔内的稳定性。这些模型的第二个目标是帮助确定磁反转年表中最不可靠的部分。另一个目标是检查极性转变数据和平均场数据，以确定是否有统计上显著偏离地球磁场轴对称。重点将放在结合所有上述数据分析与发电机（及相关）理论。

The PI will continue to develop new methods to analyze the statistical structure of the magnetic field reversal chronology, in particular, to relax the constraint applied to all previous statistical analyses of reversal chronologies that reversals occur instantaneously. One of the main reasons for doing this is to examine the core's stability properties in the time intervals that include polarity transitions. A secondary goal of these models is to help identify the most unreliable sections of the magnetic reversal chronology. An additional goal is to examine polarity transition data and mean field data to determine if there are statistically significant departures of the Earth's magnetic field from axial symmetry. Emphasis will be placed on combining all the above data analyses with dynamo (and related) theory.
