Magneto coriolis waves
Web22 okt. 2024 · Several possible interpretations have been proposed so far. Waves in the presence of stratification, rotation and a magnetic field, the MAC waves (for Magneto–Archimedes–Coriolis, e.g., Knezek and Buffett 2024), are a natural candidate in the case of a sub-adiabatic heat flux below the CMB – an issue that is currently debated, … Web23 mei 2024 · While the research exhibits magneto-Coriolis waves near seven-year period, the question of the existence of such waves that would oscillate at different periods, however, remains. Dr Gillet added, “Magnetic waves are likely to be triggered by disturbances deep within the Earth's fluid core, possibly related to buoyancy plumes.

Web15 mei 2024 · A new mechanism of large-scale magnetic fields generation is studied, which is based on creation of mean electromotive force through interactions between distinct Lehnert (magneto-Coriolis) waves. The crucial feature of this mechanism is that it does not require magnetic diffusivity to operate, in contrast to the hitherto known standard … Web31 mei 2024 · 研究人员发表在《美国国家科学院院刊》上的一篇论文写道，这些波被称为磁科里奥利波（magneto-Coriolis waves），因为它们是沿地球自转轴排列并移动的巨大磁柱，磁场强度在赤道最强。
Web18 mei 2024 · Neglecting the fast modes that are essentially slightly modified inertial waves, we focus on the slower branch of modes traditionally called magneto–Coriolis (MC) modes. We focus on the magnetostrophic limit, an approximation that neglects the fluid inertia for these modes by setting the magnetic Rossby number E η equal to zero, converting the … WebSeveral types of waves in rotating magnetized fluids have been proposed to explain equatorial oscillations with similar high frequencies. Among these are non-axisymmetric Alfvén waves, magneto-Coriolis waves and, in the presence of fluid stratification, magnetic-Archimedes–Coriolis (MAC) waves.
