Harmonic Constants
Tidal Predictions
Tidal variations can be represented by summing a series of harmonic terms of the form:
Hn cos (σnt − gn)
where Hn is an amplitiude in metres, gn is a phase lag on the Equilibrium Tide at Greenwich in degrees, σn is an angular speed and t is time.
Listed below are the mean value Z0 and the four largest Harmonic Constants (Harmonic Constituents, M2 S2 O1 & K1). To produce a full accurate tidal prediction it is often necessary to use more than 100 of these harmonic terms. These results were generated by tidal analysis using tide gauge data spanning the dates listed.
