根据地磁资料太阳经向环流的长期变化：太阳发电机理论的含义
Long-term variations in solar meridional circulation from geomagnetic data: implications for solar dynamo theory
摘要：
地磁活动在11年的太阳黑子周期中有两个主要的活动峰，这两个活动峰是由两类太阳物质引起的：日冕物质抛射和高速太阳风流，它们的数量和强度的变化分别与太阳环向场和极向场的变化有关。从两个aa指数峰值之间的滞后的长期变化，我们得到太阳经向环流的长期变化。我们使用这些关系来测试通量传输太阳发电机理论，并解释一些众所周知的太阳活动周期的特点。基于这些关系，我们给出了第24周太阳黑子活动极大值（2011年4月）的振幅（125）和历元的预测。
英文摘要：
Geomagnetic activity has two main peaks in the 11-year sunspot cycle caused by two types of solar agents: coronal mass ejections and high speed solar wind streams, whose variations in number and intensity are related to the variations in solar toroidal and poloidal fields, respectively. From the long-term variations in the lag between the two aa-index peaks we derive the long-term variations in solar meridional circulation. We use these relations to test the flux-transport solar dynamo theory and to explain some well known characteristics of the solar cycle. Based on these relations, we give a prediction for the amplitude (125) and epoch of the maximum (April 2011) of sunspot cycle 24.
