From: Classification of monthly tidal envelopes in mixed tide regimes
Example procedure for and results of calculating an actual monthly tidal envelope, using sea levels from Dokdo, Korea (August 1 to 31, 2009) and Eqs. (5a), (5b), (6), (7), (8a), and (8b): (a) potential maximum upper (PEU, red) and lower (PLE, green) tidal envelopes, compared to actual tidal heights (grey); (b) the tidal characteristic function, C, that is the ratio between actual tidal heights and PUE; (c) tidal characteristic function envelopes, CU and CL, derived from interpolation of the maximum daily peaks and troughs of C; and (d) actual upper (UE, purple) and lower (LE, yellow) tidal envelopes, calculated by multiplying PUE by CU and CL respectively.
