Gravity anomaly definition
Webanomaly. 1. A deviation from uniformity in physical properties; a perturbation from a normal, uniform, or predictable field. 2. Observed minus theoretical value. 3. A portion of a geophysical survey, such as magnetic or gravitational, which is different in appearance from the survey in general. 4. WebNov 8, 2024 · The expression in Eq. () shows that the definition of the gravity anomaly differs from the gravity disturbance by a term \(2r^{ - 1} T\) that involves the disturbing potential.Another way of explaining the difference between the gravity disturbance and anomaly is to separate the actual and normal gravity.
