Abstract:
      An improved procedure for extracting the radiational S2 tide from analyzed S2 is presented in this paper. The major improvement is that the nonlinear constituents are eliminated from the analyzed principal semidiurnal tides on the basis of the "credo of smoothness" of admittance before using the procedure given by Zetler. The semidiurnal radiationai S2 tides for 42 stations along China's coasts are calculated using the method presented in this paper, and, for comparison, the results from Zetler's method are also given. In addition, the radiational S2 tides for 10 stations are analyzed with the response method. The results show that the mean amplitude ratio (radiational to gravitational) is 0.17, the mean phase difference (radiational minus gravitational) is 119° for China's coasts.
