BALWOIS 2010 CONFERENCE, 25-29 May 2010, Ohrid, Republic of Macedonia CONCLUSIONS • The model of global water redistribution during solar cycles depends on the proper value of the transfer coefficient between the homogeneous elastic sphere and the real Earth. The value of the transfer coefficient k varies between 5.4 and 10.5. In case of great MSL changes, the value of k is 10.5 and in case of small MSL amplitudes this coefficient is closed to 6. It is possible to determine the value of k by means of all data of temporal changes of the continental water storage. • The proposed model of global water redistribution determine the relationships between the observed periodical oscillations at the solar activity frequencies of the Earth rotation, mean sea level and ice thickness accumulation rate over the polar continental ice sheets. It is possible to reconstruct the periodical behavior of the global hydrological cycles by means of available astronomical data, or to reconstruct Earth rotation data by means of available hydrological and glacial data.
