Moving Window Tidal Analysis

The characteristics of the M2 (periode: 12.42h) tidal current can be described by the 4 parameters:

  • maximum current velocity,
  • eccentricity of the tidal ellipse,
  • direction and
  • phase angle

The estimation of these 4 parameters in a time window that was shifted step by step along the measured time series of surface currents allowes to track their variability in time and applying the procedure at each gridpoint of the observed area gives an overview of the spacial distribution.

Variability of the tidal direction.
