Вращение Земли и климатические процессы
The work is devoted to the consideration of geophysical processes that cause the motion of the pole and changes in the length of the day. Particular attention is paid to the Chandler wobble. The method of its extraction and geodesic excitation reconstruction is developed. Atmospheric and oceanic excitation functions are investigated in the Chandler frequency band.
Using the Earth’s gravity field data from GRACE satellites, the first coefficients of the gravitational potential decomposition are analysed in terms of the effect of the corresponding mass redistribution on the Earth's rotation. The classical theory of rotation of the Earth with a liquid external and solid inner core is given. On its basis, the Euler-Liouville equations are generalized to the case of the triaxial Earth with oceans. The work also provides statistical analysis of the Earth rotation parameters predictions. The relationships of the Earth's rotation and climate processes are discusses.
