Upon deeper reflection, I sense a disturbing potential.
2.
The separation between these two surfaces is called the undulation of the geoid, symbol N, and is closely related to the disturbing potential.
3.
Many observable quantities of the gravity field, such as gravity anomalies and deflections of the plumbline, can be expressed in this disturbing potential.
4.
The disturbing potential "'T "'is numerically a great deal smaller than "'U "'or "'W "', and captures the detailed, complex variations of the true gravity field of the actually existing Earth from point-to-point, as distinguished from the overall global trend captured by the smooth mathematical ellipsoid of the normal potential.
