F = (O₁+K₁)/(M₂+S₂)
This formula uses 5 Variables

Variables Used

Form Number - Form Number is the ratio of the sum of the amplitudes of the major constituents.
Principal Lunar Diurnal Constituent - Principal Lunar Diurnal Constituent refer to the diurnal (daily) constituents of a fictitious moon which has a fixed circular orbit in the mean plane of the real moon.
Lunar Solar Constituent - Lunar Solar Constituent refers to the cyclical motions of the Earth, Sun, and Moon system that have a measurable effect on the tides.
Principal Lunar Semi-Diurnal Constituent - Principal Lunar Semi-Diurnal Constituent also known as the M2 tidal constituent represents response of ocean to the gravitational forces of the moon, which cause the rise and fall of sea levels.
Principal Solar Semi-Diurnal Constituent - Principal Solar Semi-Diurnal Constituent refers to one of the dominant tidal components in the ocean.

STEP 1: Convert Input(s) to Base Unit

Principal Lunar Diurnal Constituent: 3 --> No Conversion Required
Lunar Solar Constituent: 12 --> No Conversion Required
Principal Lunar Semi-Diurnal Constituent: 8 --> No Conversion Required
Principal Solar Semi-Diurnal Constituent: 11 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F = (O₁+K₁)/(M₂+S₂) --> (3+12)/(8+11)

Evaluating ... ...

F = 0.789473684210526

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 formula is defined as the ratio of the sum of the amplitudes of the major constituents, expressing how relatively important the diurnal contributions are. Form Number is denoted by F symbol.
