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.

9902969 GlatzmaierPI建议继续使用Glatzmaier-Roberts模型对地球核心的对流和磁场产生进行计算研究，该模型产生了第一个地球发电机的动态自洽计算机模拟。 特别是，他建议研究地幔和固体内核之间重力耦合的潜在一阶效应以及地幔进动对流体内核动力学的影响。 PI还希望通过模拟获得对地球发电机模拟的更大信心，使用Glatzmaier-Roberts模型的修改版本，D。Lathrop在马里兰州大学，并单独资助。
