Changes in the elements of the Earth system are closely *** the key factors linked with hydrological changes is significant for in-depth analysis of hydrological *** study chooses polar motion,which is the movement of the Earth’s rotational axis relative to its crust,as a key factor in the investigation of the physical processes of its interaction with several hydrological ***,the statistical relationships between polar motion and multi-hydrological elements(i.e.,precipitation,evaporation,runoff,and terrestrial water storage)are investigated,using trend analysis,mutation analysis,cycle analysis,and correlation analysis methods,from basinal to global and from intra-annual to inter-annual ***,their interactions are *** study quantifies the effect of hydrological changes on polar motion using the excitation *** explores the effect of polar motion on hydrological changes based on the theory of equilibrium tides and atmospheric *** results show that they are significantly correlated and abruptly changed at a similar ***,regional to global hydrological changes can significantly excite polar *** April 2002 to June 2020,the global terrestrial water storage decreased significantly(by approximately−4.68 mm yr^(−1)),which significantly drove polar motion towards the direction of the Greenwich Meridian(by approximately 4.32 mas yr^(−1)).Changes in regional terrestrial water storage also contributed significantly to directional changes in polar motion around 2005 and ***,polar motion can perturb the Earth’s centrifugal force system and generate equilibrium tides,and thus further cause changes in sea-level pressure,wind,and water vapor *** show that polar motion-induced water vapor flux divergences correlate significantly with actual precipitation and terrestrial water storage changes in the Yangtze River and the Pearl River *** correlations are also significant when
