W

Word -> "Mot"	Symbol	Unity	Definition
Wave -> "Vague"			Commonly the deformation that affects the surface of a liquid.
Wave age -> "Age de vague"			The ratio of wave speed to wind speed for "Wind waves".
Wave climate			The "Sea state" statistic description.
Wave-current interaction -> "Interaction courant-vagues"			When a wave system encounters a current system, the "Wave height", the "Wavelength" and the "Wave energy" are affected.
Wave direction -> "Direction des vagues"		deg	The direction from which the waves are coming: the conventional definition of the "Wind direction" [1]. Or the direction to which the waves are going: the common definition of the "Current direction"[1]. See also "Mean wave direction", "Peak direction", "Direction of wave propagation".
Wave energy -> "Energie des vagues"			See "Directional spectral density function", "Energy spectrum", "One-dimensional spectrum".
Wave envelope -> "Enveloppe des vagues"			The envelope of the wave signal in the meaning of signal analysis.
Wave generation -> "Génération de vagues"			See "Gravitational pull", "Wind", "Seismic disturbances".
Wave group -> "Groupe de vagues"			Sequence of waves which heights exceed the mean.
Wave height -> "Hauteur de vague"			See "Zero upcrossing wave height" and "Zero downcrossing wave height". See also "Crest-to-trough height".
Wavelength -> "Longueur d'onde"			Distance covered during the duration between two zero up-, or two zero down-, crossings. See also "Crest wavelength" and "Dispersion relationship".
Wave period -> "Période de vague"			Duration between two up-, or two down-, crossings of the mean level of the "Surface elevation". See also "Average wave period", "Crest period", "Mean spectral period", "Peak period", "Spectral wave period","Spectral wave period", "Trough period".
Wave train -> "Train de vagues"			Series of waves that travel together.
Weakly nonlinear sea -> "Houle approximée linéaire"			Defined as a sea in which the first order approximation representing waves as a superposition of independent random components, is valid for the considered application. See also"Superposition".
Wideband sea -> "Houle bande large"			Wave system which has a large domain of frequencies: the "Narrowness parameter" is over a fixed threshold (0.3 to 0.4) The "Wave envelope" function changes quickly with time.
Whitecapping -> "Embruns"			The creation of white froth by wind on the top of a wave crest.
Wind -> "Vent"			See also "Wind waves", "Wave generation".
Wind current -> "Courant dû au vent"			A surface water current generated by the tension of the wind, and modified by two simultaneous phenomena: a surface action by the mean wind and the Coriolis effect.
Wind direction -> "Direction du vent"			The direction from which the wind is blowing. See also "Wave direction".
Wind energy transfer -> "Transfert d' énergie du vent aux vagues"			See "Wind waves", "Rate of energy dissipation", "Rate of non linear transfer", "Rate of wind energy transfer".
Wind sea -> "Mer de vent"			Kind of gravity waves longer than "Chop": period beyond five seconds. They are generated by local wind. See "Wind waves".
Wind speed -> "Vitesse du vent"			Speed of the air particles, with a mean component and a fluctuant component.
Windward -> "Au vent" -> "Direction du vent"			See "Wind direction".
Wind waves -> "Vagues dues au vent"			Gravity waves generated by the friction of air particles at the water surface. See "Ripples", "Chop", and "Wind sea".
