Eng ID Term Definition
5961
wave: storm
A wind-generated sea surface wave of great HEIGHT. See STORM SURGE.
5962
wave: surface
A progressive GRAVITY WAVE in which the disturbance (that is, the particle movement in the fluid mass as well as the surface movement) is co... more
A progressive GRAVITY WAVE in which the disturbance (that is, the particle movement in the fluid mass as well as the surface movement) is confined to the upper limits of a body of water. Strictly spea­king this term applies to those progres­sive GRAVITY WAVES whose celerity depends only upon the WAVE LENGTH.
5963
wave: tidal
The wave motion of the TIDES. In popular usage, any unusually high (and therefore destructive) water level along a SHORE. It usually refers ... more
The wave motion of the TIDES. In popular usage, any unusually high (and therefore destructive) water level along a SHORE. It usually refers to either a STORM SURGE or TSUNAMI.
5964
wave: tide
See TIDE.
5965
wave: transitional water
A progressive GRAVITY WAVE in water whose DEPTH is less than 1/2 but more than 1/25 the WAVE LENGTH. Often called shallow water wave.
5966
wave: transverse
A WAVE in which the direction of propagation of the WAVE is normal to the displacements of the medium, for example, a vibrating string. The ... more
A WAVE in which the direction of propagation of the WAVE is normal to the displacements of the medium, for example, a vibrating string. The GRAVITY WAVE in which fluid parcels move in circular ORBITS is an example of a mixed transverse-longitudi­nal wave.
5967
wave: trochoidal
A progres­sive OSCILLATORY WAVE whose form is that of a prolate cycloid or trochoid. It is approximated by WAVES of small AMPLITUDES.
5968
wave: ultrashort
A RADIO WAVE shorter than 10 METRES.
5969
wave: wind
A WAVE resulting from the action of WIND on a water surface. See FETCH.
5970
wave age
The state of development of a wind-generated sea surface wave, conveniently expressed by the ratio of wave speed to wind speed. WIND SPEED i... more
The state of development of a wind-generated sea surface wave, conveniently expressed by the ratio of wave speed to wind speed. WIND SPEED is usually measured at about 8 METRES above STILL WATER LEVEL.
5971
wave base
The greatest DEPTH at which SEDIMENT on the SEAFLOOR can just be stirred by the oscillating water.
5972
wave crest
The highest part of a WAVE.
5973
wave deltas
See WASHOVERS.
5974
wave direction
The direc­tion from which WAVES are moving.
5975
wave forecasting
The theoretical determination of future wave characteristics; usually from observed or predicted meteorological or oceanographic PHENOMENA.
5976
waveform
The graphical representation of a WAVE, showing variation of AMPLI­TUDE with time. Also written as two words.
5977
wave front
The leading side of a WAVE.
5978
wave generation
The creation of WAVES by natural or mechanical means. In WAVE FORECASTING the growth of WAVES caused by a WIND blowing over a water surface ... more
The creation of WAVES by natural or mechanical means. In WAVE FORECASTING the growth of WAVES caused by a WIND blowing over a water surface for a certain period of time. The area involved is called the generating area or FETCH.
5979
wave group
A series of WAVES in which the WAVE DIREC­TION, WAVE LENGTH, and WAVE HEIGHT vary only slightly.
5980
wave height
The vertical distance between a WAVE CREST and the preceding WAVE TROUGH.
