diurnal wave
|
has a single high and low tide each lunar day. common in shallow inland seas. gulf of Mexico. has a tidal period of 24 hours 50 minutes
|
|
|
perigee
|
when the moon is closet point to Earth causing tidal ranges
|
|
|
perihelion
|
the Earth is closet to the sun make large tidal ranges
|
|
|
tidal bore
|
a wall of water that moves up certain low lying rivers due to an incoming tide
|
|
|
wave steepness
|
the ratio of wave height to wave length. if the wave steepness exceeds a ratio 1:7 it breaks.
wave height/wave length |
|
|
tide - generating wave
|
when the resultant force has a significant horizontal component, that is tangent to Earth's surface , it produces tidal bulges on Earth.
|
|
|
aphelion
|
the Earth is further away from the sun causing small tidal ranges.
|
|
|
spilling breaker
|
result from a gently sloped ocean bottom, which extracts energy from the wave, producing turbulent mass of air and water that runs down the front slope of wave.
|
|
|
capillary waves
|
commonly known as ripples, ocean surface into small, rounded waves with V-shaped troughs and wavelengths less than 1.74 cm
|
|
|
internal wave
|
associated with pycnocline, the movement of water of different densities develops below the surface.
