If you also consider Moon And the effect of the sun on the tide, and the declination change of the sun and the moon and the change of the earth's distance are not considered for the time being. When we only discuss the joint action of the sun and the moon's tide generating forces in terms of the average situation, it is obvious that the tide ellipsoid caused by the moon and the sun has the same long axis direction in the synoptic day, because the tide height is superposed with each other, forming the synoptic spring tide. In fact, in many places, the time of spring tide is slightly delayed. Therefore, the time of spring tide is one or two days after the full moon and the new moon.
