Field verification of quasi-determinism theory for wind waves in the space–time domain

Profiles of exceptionally large waves in wind seas were obtained using a gauge array that was nearly aligned in the dominant wave direction; the length of these profiles ranged from 1.5 to 3.0 times the dominant wavelength. The profiles were also obtained through calculations using the quasi-determinism theory from the datasets of the sea states. The possibility to observe waves in the space–time domain enables us to obtain a remarkable confirmation of the quasi-determinism theory.
