| Abstract: |
| A practical procedure is proposed for the analysis of short period observations of tidal streams and tidal elevations using the electronic computers. The observational series to be analysed consists of several subseries. In general, the period of the subseries should be about a whole day, though the incomplete，fragmental or even individual records may also be used in the analysis. But as many (at least one) complete subseries as possible should be used so as to get reliable harmonie constants. The estimation of the errors of the harmonic constants can a1so be given if three or more complete subseries are available. In this paper, the formulas numbered (1) , (2) , ... are provided for the use of practical analysis and those labeled (a) , (b) , ... are given in the explanations.
To take the radiational tide into account, the effect of the solar semidiurnal atmospheric pressure wave S2 (p) on ocean tides is discussed. The comparison between the horizontal pressure gradient of S2(p) and S2 component of horizontal tide-generating force gives an estimation that the radiational tide S2 can reduce the amplitude and delay the phase of the gravitational tide S2 to the extents of 1/30 and 5.6° respectively.
To reject the observations with large deviations from the normal values, a criterion is suggested. |
