摘要

大气和海洋大尺度环流建模长期以来忽略了地球重力-旋转力的水平分量,最近有人对这一做法提出了质疑,本文针对这一质疑,证明了将坐标转换成位势坐标并不存在这种水平力。这一框架应被理解为进一步完善此类地球物理模型的理由和依据(如有必要)。

There is no horizontal gravity force in geopotential coordinates.

In response to a recent challenge to the longstanding practice in modeling large-scale circulations in the atmosphere and ocean that neglects any horizontal component of Earth's gravity-rotation force, this paper demonstrates that a coordinate transformation into geopotential coordinates has no such horizontal force. This framework should be understood as the justification for and, if warranted, the basis for making further refinements to such geophysical models.
