Climatic spectra of wind waves including extreme situations

The results of the hindcasting of wave fields based on spectral models are the database for the climatic spectra calculation. The calculations were performed for each synoptic term over a time interval exceeding 40 years. We developed a procedure for the classification the wave spectra in different seas. It is possible to present the whole variety of the spectral structure of waves as five classes of frequency-directional (two-dimensional) spectra. We calculated the probabilities of the occurrence, of these classes (i.e., the climatic spectra) in different seas. We present estimates of the spectra of different classes for the White and Bering seas that are possible with return periods 1 and 100 years.
