AbstractThe monthly mean numbers of polar faculae in the time interval of 1951 August to 1998 December, from observations of the National Astronomical Observatory of Japan are used to investigate the reasons which mathematically result in the asynchronization of high-latitude solar activity between the northern and southern hemispheres. It is found that the monthly mean numbers of polar faculae in the northern hemisphere three months lead those in the southern one, which should mathematically lead to phase asynchrony of the hemispheric polar-facula activity but with a slight effect. The Schwabe period length for the polar-facula activity in one hemisphere obviously differs from that in the other, which should also lead to phase asynchrony of the hemispheric polar-facula activity. It is the low-frequency components of the hemispheric polar-facula activity in period scales around the Schwabe cycle that are responsible for its strong phase synchronization. In the high-frequency components, there is a strong phase mixing, which should also lead to phase asynchrony of the hemispheric polar-facula activity.
