Oceanic Tides

• Tidal Amplitude | High and Low Tide Times | Surge Amplitude

Tidal Amplitude

Gives the tidal amplitude in centimeters. This parameter includes the expected tide as well as the Surge Amplitude from weather influences on the seawater level.

tidal_amplitude:cm

Examples

• Tidal oscillation in France near Bordeaux

Surge Amplitude

surge_amplitude:cm

The surge amplitude gives information about the storm related abnormal rise in seawater level compared to the usual expected tide. The surge is influenced by the orientation of the coast line with the storm track, the size and intensity of the storm and the local bathymetry.

Examples

• The surge amplitude during tropical storm Isaias at the coast of North Carolina in early August, 2020:
