Form Number Formula

Form Number = (Principal Lunar Diurnal Constituent+Lunar Solar Constituent)/(Principal Lunar Semi-diurnal Constituent+Principal Solar Semi-diurnal Constituent)
F = (O1+K1)/(M2+S2)

What are Tides?

Tides are very long-period waves that move through the oceans in response to the forces exerted by the moon and sun. Tides originate in the oceans and progress toward the coastlines where they appear as the regular rise and fall of the sea surface.

Define Tide Harmonic Analysis

Harmonic Analysis of Tide is the mathematical process by which the observed tide or tidal current at any place is separated into basic harmonic constituents. Even without resorting to a mathematical discussion, one can readily see this process by graphical representation.

How to Calculate Form Number?

Form Number calculator uses Form Number = (Principal Lunar Diurnal Constituent+Lunar Solar Constituent)/(Principal Lunar Semi-diurnal Constituent+Principal Solar Semi-diurnal Constituent) to calculate the Form Number, The Form Number is defined as the ratio of the sum of the amplitudes of the major constituents, expressing how relatively important the diurnal contributions are.
