摘要:

A detailed Power Spectrum Analysis applied on the daily polarities of the inferred interplanetary magnetic field, published by Svalgaard, has pointed out that the main periodicity apparent in these data is 27–28 days, which suggests a recurrency of a 2‐sector structure. There is also a secondary periodicity of 13–14days which mainly appears in the years of the descending branch of the solar cycle and superimposes on the 2‐sector structure, transforming it into a 4‐sector structure.
