Fast Magneto-Coriolis Modes and Pressure Torques arising from Torsional Alfvén Modes in Planetary Cores. PhD Thesis, Université Grenoble Alpes WebVarious types of waves exist in the Earth’s core. Waves associated with the magnetic field can leave a signature in the observed geomagnetic field, which may allow one to infer properties of the core. Among those, a balance of magnetic, Coriolis and pressure forces forms a type of waves known as Magneto-Coriolis (MC) waves. su 大学略称
