A

  • Absolute reference: Galilean reference frame (without acceleration).
  • Admittance: the ocean's response, depending on the frequency, to the action of the generating force.
  • Age of the tide: time interval between the syzygy and the maximum range of tide that follows.
  • ALLENVI: Environmental alliance.
  • Altimetry: measurement of the height of water using spatial techniques.
  • Amphidromic points: points located at sea around which the tide wave appears to turn.
  • Amplitude: difference between the height of a high or low tide and the mean level. This term is often used in error to designate the range of tide.
  • Apparent time: true solar hour angle.
  • Argument number: method for designating the components of the tide, using a 6-figure number, making it possible to identify the astronomical parameters from which they are derived and deduce from them their period.
  • Ascending node: point at which the lunar orbit and the ecliptic intersect in the direction of movement of the Moon from the Southern to the Northern hemisphere.

 

B

  • Backrush current: current generated by the slope of the free surface, excluding the action of the tide.
