dc.description.abstract | The harmonic representation of inequalities
(HRoI) is a procedure for tidal analysis and prediction that
combines aspects of the non-harmonic and the harmonic
method. With this technique, the deviations of heights and
lunitidal intervals, especially of high and low waters, from
their respective mean values are represented by superpositions
of long-period tidal constituents. This article documents
the preparation of a constituents list for the operational
application of the harmonic representation of inequalities.
Frequency analyses of observed heights and lunitidal
intervals of high and low water from 111 tide gauges along
the German North Sea coast and its tidally influenced rivers
have been carried out using the generalized Lomb–Scargle
periodogram. One comprehensive list of partial tides is realized
by combining the separate frequency analyses and by
applying subsequent improvements, e.g. through manual inspections
of long time series data. The new set of 39 partial
tides largely confirms the previously used set with 43 partial
tides. Nine constituents are added and 13 partial tides,
mostly in the close neighbourhood of strong spectral components,
are removed. The effect of these changes has been
studied by comparing predictions with observations from 98
tide gauges. Using the new set of constituents, the standard
deviations of the residuals are reduced on average by 2.41%
(times) and 2.30% (heights) for the year 2016. The new set
of constituents will be used for tidal analyses and predictions
starting with the German tide tables for the year 2020. | en_US |
