Spring & Neap Tides
Watch how the alignment of the Sun, Earth, and Moon creates spring tides (maximum) and neap tides (minimum) through combined gravitational forces.
Tidal Bulge Force Field
Visualize the differential gravitational force that creates two tidal bulges -- one facing the Moon and one on the opposite side. Explore the inverse-cube law.
Tidal Bore Simulation
A steep wavefront surges upstream as the incoming tide funnels into a narrowing estuary. Adjust channel geometry and tidal range to see bore formation.
Bay of Fundy Resonance
The world's highest tides arise from resonance -- the bay's natural oscillation period nearly matches the lunar tidal period. Tune the forcing to see amplification.
Tidal Locking
Watch gravitational friction gradually synchronize a moon's rotation with its orbit, explaining why we always see the same face of our Moon.
Amphidromic Points
Ocean tidal nodes where amplitude is zero, with cotidal lines radiating outward. The Coriolis effect drives the tide wave to rotate around these points.
Tidal Harmonic Analysis
Decompose real tides into constituent frequencies: M2 (lunar), S2 (solar), K1, and O1. Adjust amplitudes to create semidiurnal, mixed, or diurnal tides.
Tidal Power Generation
A tidal barrage captures potential energy from the height difference between ocean and basin. Watch turbines spin and track power output through the tidal cycle.
Internal Ocean Tides
Hidden waves oscillate at the thermocline boundary deep below the surface, generated when tidal currents flow over underwater mountains and ridges.
Laplace Tidal Equations
The shallow-water equations on a rotating domain, showing how Coriolis forces shape Kelvin waves, Poincare waves, and the global tidal pattern.
