Interpretation of Variations of the Earth’s Vector of Rotation Using Inverse Solution

Abstract

Global geophysical processes cause variations of the Earth’s vector of rotation. If only little information on these processes is available, it is suitable to consider the solution of the Euler-Liouville equations as an inverse problem. A global oscillation of the sea level (with a 4–5 years period) between the north and the south hemisphere of the Earth could be proved in this way for the first time.
