摘要

This paper presents a feasible status report on the responses of the ocean to the Chandler wobble through analyses of sea#x2010;level and sea#x2010;surface temperature variations. The analysis of sea level employs a method to determine the simplest impulse response system of ocean to the Chandler wobble by a least#x2010;squares fitting after operation of an optimal band#x2010;pass filter. The observed amplitudes of pole tide in sea level are about 1.13 times as large as the equilibriums in the Pacific, while their phase differences show about 4#xB0; with respect to the equilibriums. However, Honolulu in the central Pacific shows an amplitude factor of 2.5 and a phase difference of 45#xB0;. The well#x2010;known enhancements of the pole tide in the North Sea and the Baltic Sea are also confirmed.
