The problem of identifying and quantifying deterministic features of random wind wave field in experimental data is addressed. On the basis of weakly non-linear consideration of wave dynamics it is shown that the so called "slave" or "forced", or "bound" harmonics play key role in the higher-order wave statistics. We suggest a new approach to find the higher order correlators of wave field from spatio-temporal wave data. The correlators are used as indicators quantifying the presence of quasi-regular wave patterns. An analysis of laboratory data obtained by G. Caulliez and F. Collard (1999) showed that the patterns manifest themselves in pronounced non-gaussianity strongly localized in the Fourier space.
