    Thinking about the mechanism of geomagnetic polarity reversal

    • 摘要: 地球磁场极性在地质历史中发生过相当频繁的倒转。作者将地球内部划分为岩石圈—软流圈—中圈—液圈—固核等5个动力学圈层,认为中圈与固核间可异步旋转;地球偶极磁场由中圈与固核异步旋转时所驱动的液圈中的封闭涡流与银河系磁场作用产生;该偶极子场极性由地球所通过的银道面上侧或下侧磁场方向及液圈涡流的方向共同决定,二者之一反向,极性发生倒转。
      Abstract: Geomagnetic polarity reversal was often happened in the geologic history. The author tries to probe its mechanism. In the paper, Earth sinterior is divided into five dynamics layers: lithosphere, rheosphere, mesosphere, liquid sphere and solid nucleus. It is considered that the mesosphere and solid nucleus may asynchronously rotate, and this motion drives closed-vortexes in the liquid sphere. Earth magnetic dipole field originates from each other effect between Galaxy magnetic field and the closed-vortexes in Earth's liquid sphere.The geom agnetic polarity depends on the directions of Galaxy magnetic field and the closed-vortexes in the liquid sphere.While one of the two changes its direction,geomagnetic field changes its polarity.
