Abstract

According to Xiaodong Song et al.’s study about difference rotation in the Earth’s inner core, a physical model of lunar motion changing the angular momentum of the Earth’s circles is presented in this work. The Lunar motion makes there be a huge gap existing in the core angular momentum between far lunar hemisphere and near lunar hemisphere. The gap results in the difference rota-tion in the Earth’s inner core, meanwhile, it increases the angular velocity of far lunar hemisphere and decreases the angular velocity of near lunar hemisphere. The Earth’s liquid outer core gene-rates an astro-geodynamical effect including the difference rotation among the Earth’s circles. It is found that when the moon moves into the apogee or the perigee of the lunar orbit, and the moon phase is the upper and lower chords (i.e. semi-diameter place), the true anomaly of the moon will change from 270-degree back (or forward) to 90-degree; this results in the mantle shell of the Earth westward, and forms lunisolar precession, the vernal equinox westward and Chandler polar motion.

Highlights

Formation mechanism of lunisolar precession and lunar orbit nodes regression is still a scientific conundrum
According to difference rotation research achievements presented by Song Xiaodong et al for the earth’s inner core, the author puts forward a physical model of “lunar orbit motion changing angular momentum of various circles of the earth”
Due to the mass of earth-moon system which is located inside the earth as well as liquid state characteristics of the earth’s outer core, it is deemed that angular momentum of all circles of the earth can be varied by lunar orbit motion so that a huge gap is generate between angular momentums of far and near lunar hemispheres of the core

Summary

Introduction

Formation mechanism of lunisolar precession and lunar orbit nodes regression is still a scientific conundrum. It is found that inner core of the earth wavers inside the liquid core along with lunar orbit motion to change the location of the earth’s center of mass. F. Cao elliptical orbit motion of the moon enters a place near the sun or the earth (that is, semi-diameter place), true anomaly of the moon changes from 270 ̊ back (or forward) to 90 ̊. Cao elliptical orbit motion of the moon enters a place near the sun or the earth (that is, semi-diameter place), true anomaly of the moon changes from 270 ̊ back (or forward) to 90 ̊ This results in lunar orbit nodes westward and Chandler polar motion. Such a finding has a significant meaning to explain the formation mechanism of lunisolar precession and spring equinox westward. Profound implications in the “Greatness in Simplicity; Rare Voice of Big Sound” said by Lao Tzu in Tao Teh King and the “Heaven and earth have made great beauty, four seasons have clear without proposed, does not talk contribution has everything” given by Zhuangzi can be experienced
