Abstract: In this paper,based on published data,the relation between the action of subtropical high and the movement of the sun and moon is systematically studied. It is proved that all types of action of subtropical high are related to various periodical action of the movement of the sun and the moon and that the forms of relation are both of periodicity Poisson and synchronous tendeney to astronomical singularities.It is also pointed that if the types of action of subtropical high are distinct, the related poriodical action of the movement of the sun and the moon and forms of relation are distinct.
