On zero-dimensional ocean dynamics

Abstract

How to study the effect of the Sun or the Moon?s gravity on ocean motion? Of course, Newton?s gravity should be considered. However, Newton?s law considers the Earth as a 0-D point, the ocean motion inside of a 0-D point of the Earth is negative 3-D, and Newton?s law becomes invalid in a negative space. In order to solve the problem, we divide the Earth into two parts, one part is the studied ocean, the other is the left Earth without the ocean. A mechanics model can be then established for the 0-D ocean dynamics.
