High-resolution, low-viscosity geodynamo simulations have been carried out on the Earth Simulator, one of the fastest supercomputers, in a dynamic regime similar to that of Earth's core, that is, in a quasi-Taylor state. Our dynamo models exhibit features of the geodynamo not only in spatial and temporal characteristics but also in dynamics. Polarity reversals occurred when magnetic flux patches at high latitudes moved poleward and disappeared; patches with reversed field at low and mid-latitudes then moved poleward.
在地球模拟器（世界上运算速度最快的超级计算机之一）上，开展了高分辨率、低粘度的地球动力学模拟，该模拟处于与地球地核类似的动态状态，即准泰勒状态。我们的发电机模型不仅在空间和时间特征方面，而且在动力学方面都展现出了地球发电机的特征。当高纬度地区的磁通量斑块向极地方向移动并消失时，极性就会发生反转；然后，低纬度和中纬度地区具有反向磁场的斑块向极地方向移动。
