Abstract |
An approach of celestial mechanics is used to consider variations in the tensor of inertia due to elastic deformations arising under the action of the centrifugal potential. The effects of influence of random actions are investigated in an example of fluctuation-dissipative perturbations of geophysical nature. A combined model of the Earth rotation fluctuations permits taking into account the stochastic components of the pole tide. It is shown that small irregular perturbations in tidal processes generate variations in the Chandler component of the pole oscillations. |
