Harmonic analysis of sea tides with description of seasonal variability of the main diurnal, semi-diurnal and shallow-water constituents
Features of modified version of extended least-squares method for harmonic analysis of sea tides taking into account seasonal tide variability in the annual tidal cycle are considered. It is demonstraited that new information obtained from the analysis and prediction of tides in White Sea, in Arctic Seas and in the North Sea considerably improves the accuracy of tides description. The validity of this method when in use for processing and revision of standard observations at polar stations and setting longterm sea level variations by a uniform series is noted.
