| Abstract: | A directional function for frequencies equal to and larger than the peak frequency of a wind-wave frequency spectrum is constructed by fitting the angular spreading based on the analytically derived directional spectrum of Wen et al.(1993,Journal of Oceanography,49(2),131-147,149-172).For frequencies smaller than the peak frequency,the directional function is obtained by comparing and analyzing existing formulas.The nondimensional wind-wave frequency spectrum of Wen et al.(1994,Progress in Natural Seience,4(4),407-427;4(5),586-596) has been used together with the directional function just mentioned to obtain the directional spectrum for easier application. |
