Geodynamo Simulations: New Physics and Comparison with Experiment

9902969 Glatzmair国际和平研究所建议继续使用Glatzmaier-Roberts模型对地核中的对流和磁场产生进行计算研究，该模型产生了第一个动态自洽的地球发电机计算机模拟。特别是，他建议研究地幔和固体内核之间潜在的重力耦合的一阶效应，以及地幔进动对流体核动力学的影响。PI还希望通过使用Glatzmaier-Roberts模型的修改版本模拟拟议的实验室实验，从而在地球发电机模拟中获得更大的信心，该实验由马里兰大学的D.Lathrop进行，并由单独资助。

9902969GlatzmaierThe PI proposes to continue computational studies of convection and magnetic field generation in the Earth's core using the Glatzmaier-Roberts model, which produced the first dynamically self-consistent computer simulation of the geodynamo. In particular, he proposes to investigate the potentially first-order effects of graviational coupling between the mantle and solid inner core and the effects of the mantle's precession on the dynamics of the fluid core. The PI also hopes to gain greater confidence in the geodynamo simulations by simulating, with a modified version of the Glatzmaier-Roberts model, a proposed laboratory experiment is being conducted by D. Lathrop at University of Maryland and is separately funded.
