Some Key Points...
-
Tides are the hydrodynamic response of the oceans to astronomical forcing.
-
Tides travel as long-wavelength, shallow-water waves; therefore speed of propagation depends on depth.
-
Coriolis deflections and existence of landmasses causes the tide wave to propagate around ocean basins as a rotary Kelvin wave.
-
Amphidromic systems exist for each tidal component.
-
Standing waves and complex amphidromic circulation may exist in channels or partially enclosed basins.
