Özet

New approaches for computing the wave growth rate due to wind induced shear instabilities are presented. The first approach is based on an analytical solution of Rayleigh’s equation for arbitrary wind profiles in the vicinity of the critical point, followed by numerical integration. The wave growth rate is obtained from the dispersion relation of the air-sea interface. The results of the first approach agree perfectly well with the numerical solution of Conte and Miles (1959) for the special case of a logarithmic wind profile. The second approach assumes a definite vertical profile for the perturbed velocity field and then makes use of the air-sea dispersion relation for computing the wave growth rate. Despite the simplicity of the approximation the agreement of the second approach with the first one is quite acceptable. Comments on the future work are given in closing.
