旋转对流在行星内部的动力学和在两极观测到的大尺度涡旋的形成中具有基本的重要性。关于这个问题的大部分工作都集中在Boussinesq体系中非磁性流体的平面层的情况。然而,考虑到木星内部电导率随观测到的涡旋深度的径向变化,在较大的磁雷诺数下,磁场对其形成和演化的影响仍然不清楚。该项目的一个方面将在于探索滞弹性区域中磁场和层结对快速旋转系统热对流开始的作用。PGR还将通过计算研究大磁雷诺数时的弱磁场对大尺度涡旋形成和演化的影响。计算将从两组初始条件开始:要么是对流不稳定的大气静止,要么是在没有磁场的情况下从湍流旋转热对流中产生的完全形成的大尺度涡旋。
英文摘要
Rotating convection is of fundamental importance in the dynamics of planetary interiors and in the formation of the large-scale vortices observed at the poles. Most work on this problem has focused on the case of a plane layer of non-magnetic fluid in the Boussinesq regime. However, considering the radial variations of the electrical conductivity in Jupiter's interior in relation to the depth of the vortices observed, the effect of magnetic fields on their formation and evolution remains unclear at large magnetic Reynolds numbers.One aspect of the project will consist in exploring the role magnetic fields and stratification, in the anelastic regime, on the onset of thermal convection for rapidly rotating systems. The PGR will also investigate computationally the effect of weak magnetic fields at large magnetic Reynolds numbers on the formation and evolution of large-scale vortices. The computation will start with two sets of initial conditions: either convectively unstable atmospheres a rest or fully formed large-scale vortices emerging from turbulent rotating thermal convection in absence of magnetic fields.
