Term
oceanic waves
Definition
created by air moving across the ocean surface
Term
atmospheric waves
Definition
created by the movement of different air masses
Term
internal waves
Definition
created by movement of water due to different densities
Term
longitudinal waves
Definition
a wave phenomenon when particle vibration is parallel to the direction of energy propagation
Term
transverse waves
Definition
a wave in which particle motion is at right angles to energy propagation
Term
orbital waves
Definition
a wave in which energy is moved along the interface between fluids of different densities, moves in orbital paths
Term
circular orbital motion
Definition
the motion of water particles caused by a wave as its transmitted through water
Term
deep water waves
Definition
an ocean wave traveling in water that has a depth greater than 1/2 the average wavelength, speed is independent of water depth
Term
shallow water waves
Definition
a wave on the surface having a wave length of at least 20x the water depth, bottom affects the orbit of water particles and speed determined by water depth
Term
capillary waves
Definition
a wave whose wave length is less than 1.74cm
Term
gravity waves
Definition
a wave whose dominant restoring force is gravity
Term
swell
Definition
a free wave by which energy put into waves by wind in the sea is transported with little energy loss across large stretches of ocean until it reaches a surf zone
Term
determiner of wave size
Definition
wind speed, wind duration, fetch
Term
Fetch
Definition
distance which wind blows in one direction
Term
wave dispersion
Definition
the separation of waves as they leave the sea by wave size
Term
decay distance
Definition
the distance over which waves change from a "choppy" sea to uniform swell
Term
spilling breaker
Definition
type of wave that forms on a gentle sloping beach
Term
plunging breaker
Definition
curling breakers that form on moderately sloped beaches
Term
surging breaker
Definition
a compressed breaking wave that builds over a short distance and surges forward as it breaks
