Airy theory -> "Théorie d'Airy"			The simplest and most commonly used wave theory: linear with the wave height.
Airy wave -> "Houle d'Airy"			Wave that obeys the Airy equations: it has a precise height, direction, and frequency.
Apparent wave height -> "Hauteur apparente de vague"	Hv	m	Mean height estimated from visual observation [1].
Average wave period -> "Période moyenne des vagues"		s	Mean of zero crossing "wave period" [1]. "Spectral wave period" from spectral moments e.g: "T01" and "T02".
